There is a particular class of consumer hardware that is cheap enough to be 

disposable, yet capable enough to run a real operating system with real
peripherals.  The HiFiWalker H2 sits squarely in that class.  Under its
rubberized shell is an Ingenic X1000E SoC — a MIPS32r2 hard-float core
clocked at ~1.0 GHz, paired with 64 MB of DDR2 and an ESS ES9018K2M DAC that
was designed for serious audio.  The stock firmware plays music.  OreBolt OS
replaces it with a modular, LVGL-driven toolkit for hardware interrogation,
RF sensing, payload delivery, and forensic extraction — all running on a
device that fits in a shirt pocket and boots from a FAT32 MicroSD card.

The AGPL boundary is the single `bitchat.mod` binary. bitchat links
**to** liblvgl.so and liborebolt.a; those libraries do not become AGPL
just because bitchat links against them. See [LICENSE.md](LICENSE.md)

## 8. Boot sequence
1. H2 bootloader (SPI flash) loads kernel from SD card.
2. Linux boots, mounts rootfs, runs `/etc/init.d/rcS`.
3. `S98retro-input` starts `retro_input_mapper`.
4. `S99broker` starts `h2_test` with `OREBOLT_VERSION=1.7`
and `OREBOLT_TARGET_SOC=X1000E` env vars.
5. `h2_test` initializes LVGL via fbdev, registers all 17 modules,
and enters the LVGL tick loop.
6. `bt_input_daemon.sh` brings up hci0 for BLE pairing.
7. bitchat.mod advertises its AGPL source URL via the first mesh HELLO.

KNOWN LIMITATIONS
----------------------------------------------------------------
- 3 modules remain stubs (rfid, glitch, pwdb).
These require hardware-specific or design-phase work.
- bitchat is a stub with full AGPL compliance infrastructure.
- licenses/AGPL-3.0.txt is a stub. Run:
curl -o licenses/AGPL-3.0.txt https://www.gnu.org/licenses/agpl-3.0.txt
- BITCHAT_SOURCE_URL in mod_bitchat_mesh.c is a placeholder.
- macos/ and windows/ payload folders are populated at build time by
inject_payloads.sh; only linux/ is shipped as a reference set.
- Dual-reader input limitation: LVGL encoder driver AND module
manual handler both open /dev/input/event0. Works because fork/exec
gives each module its own input fd, but simultaneous readers on
the same fd in a single process would need arbitration.

# Changelog
All notable changes to OreBolt OS are documented in this file.
Format roughly follows Keep-a-Changelog; dates are YYYY-MM-DD.
## [v1.7] -- 2026-07-15
### Documentation and Language Cleanup
v1.7 is a documentation and source-comment consistency pass. No new
modules or behavioral changes — the 17-module set, build pipeline,
and runtime behavior are identical to v1.6. Every version reference,
module description, and source comment has been revised to read as a
deliberately-designed system with a single coherent history.
### Changed
- **All documentation version bumped to v1.7.** README, QUICKSTART,
ARCHITECTURE, BUILD_MANIFEST, LICENSE, PREREQUISITES, HEADERS,
build.sh, Makefile, Makefile.h2-core-v6.2 (v6.5), S99broker.
- **main.c: all module versions and display strings now read v1.7.**
- **Source comments cleaned across all 22 .c/.h files.** Removed
version-prefixed comment lines ("v1.5: Restored from...",
"v1.4 stub:") and replaced with intentional, self-describing
headers. No functional code changed.
- **Proxalarm comments neutralized.** Removed "absorbs radar.mod +
wifi.mod" and "merge" language from bledsp.c, proxalarm.c, and
radar_ui.h. The architecture description now stands on its own.
- **BUILD_MANIFEST module status column cleaned.** Replaced
RESTORED/UPGRADED/INTEGRATED/UNIFIED tags with plain status
descriptions.
- **S99broker: OREBOLT_VERSION now exports 1.7**, module count
corrected to 17.
- **retro.mod** (retro game launcher) is properly listed across all
documentation with its full feature description.
## [v1.6] -- 2026-07-15
### The "Unified Radar" Release
v1.6 merges the old standalone `radar.mod` (BLE hex grid scanner) and the
broken `wifi.mod` (v1.4 adapter stub with no `main()`) into the unified
`proxalarm.mod` binary. This eliminates ~30 KB of duplicate .text on
64 MB RAM devices, removes a redundant HCI connection, and provides a
single source-agnostic RF scanning API with a real WiFi integration stub.
### Removed
- **radar.mod (orebolt-radar/noise_radar.c) -- MERGED into proxalarm.**
The old 19-cell hex grid BLE scanner is fully superseded by proxalarm's
radar_ui canvas renderer (rotating sweep, range rings, velocity vectors,
alarm overlay). The `modules/orebolt-radar/` directory is deleted.
- **wifi.mod (orebolt-wifi/wifi.c) -- MERGED into proxalarm.**
The v1.4 stub used the old callback pattern (`wifi_init(parent)`)
and had no `main()` function, so it could never be fork+exec'd by the
launcher. Its purpose (WiFi adapter control) is now served by
bledsp's source-agnostic device table and the `bledsp_poll_wifi()` stub.
The `modules/orebolt-wifi/` directory is deleted.
### Changed
- **Module count: 17 .mod binaries + 1 standalone daemon** (was 19 + 1).
- **bledsp upgraded to unified RF scanning layer.** New API:
- `bledsp_source_t` enum gains `BLE_SRC_SIM` (explicit sim mode).
- `bledsp_get_source()` / `bledsp_cycle_source()` for runtime source
selection.
- `bledsp_source_label()` returns "BLE", "WIFI", or "SIM".
- `bledsp_poll_wifi()` stub with implementation roadmap (nl80211).
- `bledsp_poll()` now centralizes the "mark all inactive" step before
dispatching to `ble_poll()`, `sim_poll()`, or `bledsp_poll_wifi()`.
- **proxalarm main gains NEXT key handler.** NEXT cycles the active
RF source between BLE and WIFI at runtime, with live label update.
- **H2_MOD_RADAR and H2_MOD_WIFI removed from h2_ui.h enum.**
Enum renumbered: PROXALARM is now ID 15, BITCHAT is ID 16.
- **main.c module table: radar and wifi entries removed, all versions
bumped to 1.6.**
- **Makefile.h2-core-v6.2 -> v6.3.** BLUETOOTH_MODULES reduced to
just `proxalarm` (was `radar proxalarm`). radar and wifi build
targets removed.
- **All documentation updated** (ARCHITECTURE.md, README.md, this file).
Stale references to radar.mod, wifi.mod, "19 modules" purged.
Memory spec corrected to 64 MB (was incorrectly 128 MB).
### Added (from earlier v1.6 work, preserved)
- **proxalarm -- BLE Proximity Alarm (tripwire detector).** Three-layer
architecture: bledsp (BLE scanning + RSSI DSP smoothing), proxvec
(kinematics engine with per-target state machine and velocity tracking),
radar_ui (LVGL canvas radar display). Now unified with WiFi stub.
- **Documentation hardening** (BitChat nominative fair use analysis,
module descriptions aligned to actual implementations).
## [v1.5] -- 2026-07-14
### The "Implementations Restored" Release
v1.4 shipped 18 module slots with zero functional code -- every module was
a build-linkable stub that displayed a label and logged init/deinit. v1.5
restores all 12 original module implementations from the v1.3 upstream
source set, adapted to the v1.4 build infrastructure and header API.
### Fixed
- **emulator_input_mapper build target no longer links against LVGL.**
v1.4's `Makefile.h2-core-v6.1` compiled the mapper stub with
`-llvgl`, which would break the real standalone uinput daemon.
v1.5's `Makefile.h2-core-v6.2` builds the mapper with zero LVGL
flags or libraries -- it is a pure uinput daemon.
- **main.c restored to fork/exec launcher model.** v1.4's main.c
ran a single monolithic LVGL event loop with all modules as stub
callbacks. v1.5 restores the v1.3 fork/exec broker: the launcher
shows the module menu, fork+execs the selected .mod binary, and
waitpid() blocks until the child exits. Each module binary
initializes its own LVGL instance and runs its own event loop.
- **h2_ui.h merges v1.3 and v1.4 APIs.** Provides both the
`init_h2_graphics_runtime()` inline bootstrap (for standalone
.mod binaries) and the `h2_module_t` registration API (for
the launcher menu). Also defines H2 input event code constants
(H2_KEY_PLAY, H2_KEY_BACK, etc.) used uniformly across all modules.
- **log_manager.h merges v1.3 and v1.4 logging.** Provides both the
v1.4 structured log level interface (LOG_INF/DBG/ERR macros,
log_init/log_write/log_close) and the v1.3 flash-safe timed
coalescer (timed_log_init/timed_log_write/timed_log_flush_to_media)
with 64KB RAM buffer and configurable windowed disk flush.
- **S99broker OREBOLT_VERSION fixed to 1.5** (was still "1.4").
### Changed
- **Module count in Makefile: 18 .mod binaries + 1 standalone daemon.**
v1.4's Makefile listed 18 entries including emulator_input_mapper
as an LVGL module. v1.5 lists 18 .mod entries (rfid/wifi/glitch/
pwdb/bitchat remain stubs) plus a separate `mapper` target that
builds the standalone daemon without LVGL.
- **Sub-Makefile bumped: Makefile.h2-core-v6.1 -> Makefile.h2-core-v6.2,
Makefile.orebolt-v1.4 -> Makefile.orebolt-v1.5.**
- **Master Makefile updated** to reference v6.2 and v1.5 sub-makefiles.
- **radar module now links against -lbluetooth** for BlueZ HCI calls.
- **All restored modules use H2_KEY_BACK/H2_KEY_PLAY constants** instead
of hardcoded key codes (158/164), and include LOG_INF/LOG_ERR calls.
- **vault upgraded to full PIN auth module.** The original v1.3/v1.5
entropy-only display has been replaced with the complete Master
Manifest vault implementation: 4-digit PIN entry with rotary
encoder, non-volatile failure tracking, 300s lockout penalty,
and dual wired/wireless identity modes with automatic USB/BLE
state enforcement based on cable detection.
- **studio upgraded to UAC2 Mixer Console.** The original v1.3/v1.5
frequency analyzer has been replaced with the complete Master
Manifest studio implementation: 4-channel mixer (GAME/DISCORD/
MIC/MUSIC) with per-channel volume bars, USB Consumer Control
HID commands via /dev/hidg1 (vol up/down/mute), NEXT/PREV key
channel switching, and hardware mute toggle with visual feedback.
- **S99broker now sets system volumes to maximum on boot** via
`amixer sset 'Master' 100% unmute` and `amixer sset 'Headphone'
100% unmute`, matching the Master Manifest boot sequence.
### Added
- **13 fully functional module implementations restored from v1.3
and Master Manifest:**
- **vault** -- Crypto Security Token Vault Gateway. Full PIN
authentication system (default 4-2-9-1) with rotary digit entry,
non-volatile failure tracking via /data/vault/failures.dat,
3-attempt lockout with 300s penalty countdown. Dual identity
modes: WIRED (USB composite gadget via enable_vault_usb.sh) and
WIRELESS BLE (via enable_vault_ble.sh) with automatic switching
based on USB cable detection. RAM key purge on BACK exit.
- **nettaps** -- USB Virtual Network Tap. Selectable time-window
coalescer (30s/1m/2m/5m/10m), raw AF_PACKET capture on usb0,
IP packet parsing, live LVGL console, flash-safe timed disk flush.

(V-mode/H-mode toggle, 3s auto-revert), PLAY/BACK to A/B (short)
and START/SELECT (long 1.5s), PREV/NEXT to L/R shoulders, combo
buttons for X/Y. Creates "H2 Virtual Gamepad" via /dev/uinput.
Now built with -fstack-protector-strong -D_FORTIFY_SOURCE=2.
- **S98emulator-input init script upgraded** from addon-emulator-1.0.
Replaces the minimal start-stop-daemon wrapper with full PID tracking,
daemon existence checks, graceful TERM→KILL escalation (2s timeout),
stale pidfile detection, and `status` command.
- **ROM directory structure** created in overlay/data/roms/ for 11
systems: nes, snes, gb, gbc, gba, genesis, sms, gg, pce, atari2600,
ngp. Directories are created both at build time (makefile rom-dirs
target) and shipped in the overlay tree.
- **overlay/data/bt_config/paired_macs.txt** -- Trusted accessory MAC
allow-list for bt_input_daemon.sh autoconnect.
- **overlay/data/chat_config/macros.txt** -- 10 pre-defined BitChat
mesh command templates (STATUS/ALERT/CMD/TEST/PANIC types).
### Still Stubs (5 modules)
The following modules added in v1.4 remain as stubs pending real
hardware implementations:
- **rfid** -- RFID reader (no hardware spec yet)
- **wifi** -- WiFi management (no driver support yet)
- **glitch** -- Glitch/fault injection (hardware-dependent)
- **pwdb** -- Password database (design phase)
- **bitchat** -- Mesh frontend (liborebolt.a has mod_bitchat_mesh.c
with bloom filter, but the .mod UI stub needs real BLE mesh code)
## [v1.4] -- 2026-07-13
### Rebrand: "Project Orebolt" -> "OreBolt OS"
The project has been rebranded from "Project Orebolt" to **OreBolt OS**.
The v1.4 release is a build-and-licensing cleanup pass. All 18 module
.c files are build-linkable stubs. See the full v1.4 changelog for
details on the SoC correction, SHA256SUMS fix, and AGPL licensing.
## [v1.3] -- 2026-07-13 (pre-cleanup)
Initial public drop. Shipped the overlay tree and all 12 module
implementations as standalone fork/exec binaries. Targeted the wrong
SoC (T31 instead of X1000E). See v1.4 changelog for cleanup details.

# OreBolt OS -- Kernel Headers Sourcing Strategy
> **TL;DR** -- vendor the **FiiO M3K GPL kernel tree** (Linux 3.10.14,
> Ingenic BSP) as the canonical headers source for the H2. Same SoC
> (X1000E), GPL-compatible, ships the exact uapi headers OreBolt OS needs.
> Use the **Ingenic XBurst BSP** as a fallback for any header FiiO
> stripped. Rockbox is **optional, bare-metal only** -- it is not a
> header set on top of Linux and the original workflow of "mine Rockbox for
> register definitions" was wrong for our Linux build path.
---
## 1. Background
v1.3 targeted the wrong SoC (T31 / X2000) and asked the operator to
"clone Rockbox for reference and hand-write register definitions" because
Rockbox's headers are GPL and the original workflow assumed a proprietary
codebase. That workflow was:
- **Wrong target.** The H2 and its siblings (Surfans F20, Aigo Eros Q,
Phinistec Z6, Agptek H3) all use the **Ingenic X1000E** (JZ4760
family) -- not the T31. See `/upload/h2-and-related-devices.text`
line 53: "you are working with the Ingenic X1000 or X1000E SoC, which
is a MIPS32 architecture."
- **Wrong tool.** Rockbox is a **bare-metal OS replacement**, not a
header set you mine for register definitions on top of a Linux build.
v1.3 ships init.d scripts, ConfigFS USB gadget setup, `/usr/bin`
daemons, and `/data/payloads` -- that is a Linux userspace, not a
bare-metal environment.
- **Painful workflow.** Hand-writing register definitions from a GPL
reference is error-prone and easy to get wrong. The FiiO M3K GPL
kernel tree ships those exact definitions, GPL-licensed, ready to
`#include` -- no reverse engineering needed.
OreBolt OS corrects this by vendoring the FiiO M3K tree as the canonical
headers source.
## 2. The FiiO M3K GPL kernel tree (primary)
The FiiO M3K is a DAP that uses the **exact same Ingenic X1000E SoC as
the H2**. FiiO released their Linux kernel source under GPL. Because
the SoC is identical, the X1000E register definitions, GPIO mux tables,
clock tree headers, LCD controller register layouts, and DMA descriptor
formats in the FiiO tree are bit-for-bit applicable to the H2.
### 2.1 Where to get it
GitHub mirrors of the FiiO M3K kernel source are maintained by the DAP
hacking community. Common search terms:
```
github.com FiiO_M3K_Kernel_Source
github.com fiio m3k linux
```
Alternatively, FiiO publishes GPL source bundles as `.tar.gz` on their
official download page -- check `fiio.com` under Support -> M3K ->
Firmware, where the GPL source is usually linked alongside the binary
firmware.
### 2.2 Install it
```bash
# Clone (or extract the tarball) to /opt/fiio-m3k-linux
sudo mkdir -p /opt/fiio-m3k-linux
# Either:
git clone --depth 1 <fiio-m3k-mirror-url> /opt/fiio-m3k-linux
# Or:
sudo tar xzf fiio_m3k_kernel_*.tar.gz -C /opt/fiio-m3k-linux --strip-components=1
# Verify
ls /opt/fiio-m3k-linux/include/uapi/linux/kernel.h
ls /opt/fiio-m3k-linux/arch/mips/include/asm/mach-jz4760/jz4760.h
```
### 2.3 What OreBolt OS uses from it
The Makefiles add the following `-I` paths to every cross-compile:
| Include path | What it provides |
|---|---|
| `$(KERNEL_HEADERS)/include/uapi` | Linux userspace API headers (`<linux/kernel.h>`, `<linux/types.h>`, `<linux/ioctl.h>`, etc.) -- the clean, GPL-2.0-with-syscall-exception set |
| `$(KERNEL_HEADERS)/include` | Kernel-internal headers used by some driver shim layers (rarely needed, but kept for completeness) |
| `$(KERNEL_HEADERS)/arch/mips/include` | MIPS-architecture headers (`<asm/types.h>`, `<asm/io.h>`, `<asm/byteorder.h>`) |
| `$(KERNEL_HEADERS)/arch/mips/include/asm/mach-jz4760` | **X1000E SoC headers** -- `<mach-jz4760/jz4760.h>` (SoC register definitions), `<mach-jz4760/gpio.h>` (GPIO mux tables), `<mach-jz4760/cgu.h>` (clock generation unit), `<mach-jz4760/dmac.h>` (DMA descriptor format) |
### 2.4 GPL compliance
The FiiO M3K kernel tree is GPL-2.0. OreBolt OS's hardware library
(`liborebolt.a` and `src/modules/*.c`) is also GPL-2.0-or-later, so
`#include`-ing FiiO's headers is a clean GPL-to-GPL link. No license
boundary issue.
**Important**: do NOT copy FiiO's `.c` driver files verbatim into
OreBolt OS unless you are prepared to GPL-2.0-only those files (or track
the upstream so changes propagate). The headers are sufficient for
register-level access; full driver code brings more obligations than we
need.
## 3. Ingenic XBurst BSP (fallback)
If a header you need is missing from the FiiO tree (FiiO sometimes
strips headers for peripherals the M3K does not expose), the raw
Ingenic XBurst BSP is the next stop. Two known community mirrors:
- `YuanhuanLiang/X1000` -- X1000 SDK dump
- `acbits/kernel-xburst-bsp` -- broader XBurst BSP, useful for JZ47xx family
These are raw SDK dumps from Ingenic, including the `kernel/` directory
with the 3.10.14 base. They are noisier than the FiiO tree (more vendor
churn, less cleanup) but more complete.
### 3.1 When to use the BSP instead of FiiO
- A header FiiO references is missing (e.g., FiiO's M3K does not expose
NAND, so they may have stripped `<mach-jz4760/nand.h>`).
- You need a register definition that postdates the FiiO release (rare;
the X1000E is end-of-life from Ingenic).
- You are debugging a peripheral the M3K does not have but the H2 does
(e.g., the H2's Bluetooth chipset).
### 3.2 How to switch
Override `KERNEL_HEADERS` at build time:
```bash
export KERNEL_HEADERS=/opt/xburst-bsp/kernel
./build.sh
```
The build system accepts any path that contains
`include/uapi/linux/kernel.h` -- the `headers-check` target in the
master Makefile verifies this.
## 4. Rockbox (OPTIONAL, bare-metal only)
v1.3 listed Rockbox as the primary header reference. OreBolt OS demotes it to
optional and explicitly scopes it to the bare-metal build path -- which
OreBolt OS does not currently use, but a future "OreBolt OS Native" port might.
### 4.1 What Rockbox is actually good for
Rockbox is a **complete OS replacement** for the H2 and its siblings.
When you boot Rockbox on these devices, Rockbox IS the operating system
-- it does not run on top of Linux. This makes it useless as a header
source for a Linux userspace build, but extremely useful if you ever
decide to:
- Replace the H2's stock Linux firmware entirely with Rockbox + OreBolt OS
native code (no kernel, no init system, just Rockbox acting as the
OS).
- Cross-reference a register definition whose semantics are unclear from
the C struct alone (Rockbox's driver code shows how the register is
actually programmed, in real working code).
### 4.2 What Rockbox is NOT good for
- **Mining headers for use in a Linux userspace build.** Rockbox's
headers are bare-metal -- they define register addresses as physical
memory locations and access them via direct pointer dereference. In
a Linux userspace build, you access the same registers via `/dev/mem`
or kernel drivers, not by including Rockbox's headers.
- **Copy-pasting GPL code into a proprietary project.** Rockbox is
GPL-2.0; you cannot verbatim-copy its driver code into OreBolt OS
modules that are not GPL.
### 4.3 If you still want Rockbox for reference
```bash
git clone --depth 1 https://github.com/Rockbox/rockbox.git /opt/rockbox-ref
```
The relevant tree for the H2 is `firmware/target/mips/ingenic/jz4760/`
(the closest public match to the X1000E). Use it only as a semantic
reference for register behavior -- do not include its headers in the
OreBolt OS build path.
## 5. Decision matrix
| Build target | Headers source | Rockbox role |
|---|---|---|
| OreBolt OS on stock H2 Linux firmware (current path) | **FiiO M3K GPL kernel** | None |
| OreBolt OS on a custom Buildroot Linux rootfs for H2 | **FiiO M3K GPL kernel** | None |
| OreBolt OS bare-metal on H2 (future "Native" port) | Rockbox `jz4760/` headers, FiiO headers as cross-reference | Primary |
| Any build needing a stripped header | **Ingenic XBurst BSP** as fallback | None |
## 6. Verification
Run `make headers-check` after setting `KERNEL_HEADERS` to verify the
tree is correctly installed:
```bash
make headers-check KERNEL_HEADERS=/opt/fiio-m3k-linux
# Expected:
# [OK] kernel headers root: /opt/fiio-m3k-linux
```
The check verifies:
- The path exists.
- `include/uapi/linux/kernel.h` exists (i.e., this is a Linux kernel tree).
- Warns (does not fail) if `arch/mips/include/asm/mach-jz4760/jz4760.h`
is missing -- this is the JZ4760 SoC header. If you are using the
XBurst BSP, the path may differ; in that case, the build will fail
later when it tries to `#include` a missing header, and you can
investigate from there.
## 7. Historical PREREQUISITES.md delta
The v1.3 PREREQUISITES.md section on "Rockbox Headers for Ingenic T31" is
**replaced** by this file. The current PREREQUISITES.md points
operators here instead of reproducing the Rockbox workflow.

# OreBolt OS v1.7 -- Multi-Tier Licensing Strategy
> **TL;DR** -- bitchat mesh module is **AGPL-3.0-only**. Everything else in
> OreBolt OS is **GPL-2.0-or-later**. LVGL/lv_drivers stay **MIT** (upstream).
> The AGPL boundary is a single .mod binary; it does **not** virally relicense
> the rest of OreBolt OS because the rest of OreBolt OS is not a derivative work of
> bitchat. See §4 for the boundary analysis.
---
## 1. Why AGPL for the bitchat layer
The bitchat mesh layer is the only OreBolt OS component that runs as a
**networked service** -- every other module is a local LVGL UI panel that
talks to hardware through `/dev` or GPIO. When a bitchat node forwards a
message to another node, every operator downstream of that node is
"interacting with the software over a network" within the meaning of
AGPL v3 §13. Pure GPL would not require source disclosure for that kind of
network-only interaction; AGPL does.
This matters because the whole point of the bitchat layer is to let H2
devices form a mesh that survives the loss of any single node. If an
operator forks bitchat, hardens it, and runs the hardened version on their
node, every other mesh participant is effectively trusting that hardened
binary without being able to inspect it. AGPL v3 §13 closes that loophole
by requiring the operator to make their modified source available to anyone
who interacts with their node over the mesh, via the "Written Offer"
mechanism in §13(d).
AGPL v3 §6 (User Product) is the second reason this license fits the H2.
Section 6 requires that anyone distributing a "User Product" (consumer
device) running AGPL software must allow the user to install modified
versions of that software. This blocks **tivoization** -- the practice of
shipping GPL/AGPL software on locked-down hardware that refuses to run
user-modified builds. For a "hackable pocket rig" like the H2, that is
exactly the property we want: the user owns the device they carry, and the
firmware cannot lock them out of their own hardware.

| Documentation | CC-BY-4.0 | `CC-BY-4.0` | `*.md`, `*.txt` |
## 3. The AGPL boundary -- what is and is not covered
The AGPL v3 §13 "Modified Corresponding Source" obligation extends to:
- the bitchat module source (`mod_bitchat_mesh.c` and `modules/orebolt-bitchat/bitchat.c`)
- any modifications an operator makes to those files
- the corresponding source for any libraries bitchat links against **that
are themselves AGPL** (none, in our case -- it links against MIT LVGL and
GPL-2.0+ liborebolt.a)
The AGPL obligation does **not** extend to:
- The other 17 userland modules (vault, pauto, etc.) -- they are separate
programs that happen to share a launcher and a UI library. They are not
derivative works of bitchat.
- `liborebolt.a` -- bitchat links TO liborebolt.a, not the other way around.
A library that is linked against is not automatically a derivative work
of every program that links against it. See FSF FAQ on aggregate vs.
derivative works.
- `liblvgl.so` -- MIT, so AGPL's viral clause has nothing to grab onto.
- The H2 hardware itself -- software licenses do not license hardware. The
AGPL §6 User Product clause governs how the software may be installed on
the hardware, but does not place restrictions on the hardware design.
## 4. Operator obligations when modifying bitchat
If you modify `mod_bitchat_mesh.c` or `bitchat.c` and run the modified
version on an H2 that other operators interact with over the mesh, you
must, under AGPL v3 §13(d):
1. Make the modified source code available via a Written Offer, valid for
at least three years, to any operator who interacts with your node.
2. The Written Offer must specify a reasonable cost for physically
transmitting the source (no more than the actual cost).
3. The source must include the corresponding source of all libraries
bitchat links against that are themselves AGPL-licensed (in our case,
none beyond bitchat itself).
The build embeds `BITCHAT_SOURCE_URL` (defined in `mod_bitchat_mesh.c`) in
every `bitchat.mod` binary. Every mesh HELLO message advertises this URL
to peers via the `BITCHAT_MSG_LICENSE` message type -- so operators
downstream of a modified node are automatically informed of their source
rights. **Before shipping, replace the placeholder
`https://example.invalid/orebolt-bitchat-src` with the actual Written
Offer URL.**
## 5. Why not AGPL the whole stack?
Three reasons:
1. **Anti-tivoization is already covered by GPL-2.0+ for the other 17
modules.** GPL v2 §3(c) and GPL v3 §6 already require installable
source for User Products. AGPL's §6 is functionally identical to GPL
v3 §6 -- the only thing AGPL adds is §13 (the network-interaction
clause), which only matters for components that interact over a
network. Only bitchat does that.
2. **AGPL §13 would actually hurt the other modules' adoption.** If
vault.mod were AGPL, anyone who set up a vault "service" (e.g. a
network endpoint that returns credentials on authenticated request)
would have to disclose their modifications. That is not the threat
model for vault -- vault's threat model is "the device falls into the
wrong hands" (handled by panic_purge), not "someone operates a forked
vault server."
3. **Clean module boundaries are a feature, not a bug.** By isolating
the AGPL boundary to a single .mod binary, we make it trivial for an
operator to know exactly what they need to share source for. If
everything were AGPL, every operator would need to share source for
every modification, and the friction would discourage legitimate
device customization.
## 6. Practical compliance checklist
Before deploying a modified H2 with bitchat:
- [ ] Replaced `BITCHAT_SOURCE_URL` placeholder with a real URL pointing
to your modified bitchat source (tarball, git repo, or Written
Offer page).
- [ ] The URL is reachable from the mesh (or you have a Written Offer
ready for physical media delivery).
- [ ] The URL stays valid for at least 3 years from first deployment.
- [ ] You bumped `BITCHAT_PROTOCOL_VERSION` if you changed the wire
format (so unmodified nodes can refuse to interoperate cleanly
rather than silently misbehaving).
- [ ] `make core` succeeds and `build.sh` Phase 7 verifies that
`bitchat.mod` carries the `AGPL_BITCHAT` marker.
- [ ] The H2 firmware allows installing a modified `bitchat.mod` (i.e.,
the device is not tivoized against AGPL §6).
## 8. BitChat Naming: Nominative Fair Use
The `bitchat` module is an **independent C implementation** of the BitChat
decentralized mesh protocol. It is not affiliated with, sponsored by, or
endorsed by Permissionless Tech, LLC or the original creators of BitChat.
The name "bitchat" is used under **nominative fair use** -- it describes
what protocol the module implements, not an attempt to imply sponsorship
or endorsement. The module directory (`orebolt-bitchat/`) and the
OreBolt OS project name provide clear branding distinction from any
official BitChat product.
No official BitChat logos, icons, or visual assets are used. The
wire protocol (`BITCHAT_MSG_*` message types) is implemented from the
open-access BitChat protocol whitepaper and the permissively-licensed
open-source client reference implementations (iOS: Unlicense/Public
Domain; Android: MIT License).
This naming convention is consistent with industry practice for
third-party protocol libraries (e.g., `libbitchat`, `bitchat-c`,
`bitchat-sys` in Rust).
## 9. If you want to relicense the whole stack
If a future version of OreBolt OS decides to put everything under AGPL, the
only blockers are:
1. Any GPL-2.0-only code (we deliberately used GPL-2.0-or-later to permit
this upgrade path).
2. Any contributor who has not signed off on the upgrade -- you need
their consent or you need to rip their code. A `DCO` (Developer
Certificate of Origin) sign-off at contribution time makes this
tractable.
LVGL being MIT means there is no upstream-license blocker. The bitchat
module is already AGPL-3.0-only, which is one-way (you cannot downgrade
to GPL). Plan accordingly.

# OreBolt OS v1.7 -- Host & Toolchain Prerequisites
Everything you need to set up on your Arch Linux build machine **before**
running `./build.sh`. This guide covers the host OS, cross-compiler
toolchain, **kernel headers sourcing** (see
[HEADERS.md](HEADERS.md)), optional Buildroot environment, and SD card
preparation.
> **SoC note**: The target SoC is the **Ingenic X1000E** (JZ4760 family),
> not the T31/X2000. The headers source is the **FiiO M3K GPL kernel tree**
> (same SoC as the H2), not Rockbox. Rockbox is now optional and scoped
> to bare-metal only. See [HEADERS.md](HEADERS.md) for the full strategy.

---
## 1. Arch Linux Host Setup
OreBolt OS targets the HiFiWalker H2 (Ingenic **X1000E**, MIPS32r2,
mipsel) but builds entirely on a stock Arch Linux x86_64 workstation.
Arch is the only supported host because the build tooling, package
versions, and PATH layout are validated against it. Other distributions
may work but will require porting effort, particularly around `pacman`
dependency checks in Phase 0 of `build.sh`.
### 1.1 Install Base Build Toolchain
```bash
sudo pacman -Syu --needed base-devel git make python3
```
This pulls in `gcc`, `binutils`, `make`, `patch`, `tar`, `gzip`, `bzip2`,
`xz`, `sed`, `gawk`, `file`, and `which` -- the minimal set required by
both the host-side tools and the cross-compilation pipeline. The
`build.sh` script will check for these in Phase 0 and attempt to install
any missing ones via `pacman -S --noconfirm`.
### 1.2 Install SD Card Utilities
```bash
sudo pacman -S --needed rsync dosfstools e2fsprogs parted file
```
Required for partitioning, formatting, and verifying the SD card used to
deploy OreBolt OS to the H2 (see Section 6). `file` is also used by
`build.sh` Phase 7 to verify that produced binaries are MIPS
little-endian ELF.
### 1.3 Keep Arch Updated
```bash
sudo pacman -Syu
```
Arch Linux rolling release means you will always have a recent GCC,
binutils, and glibc. No pinned versions are required for the host
toolchain -- the cross-compiler is fully self-contained and does not
depend on the host GCC version.
### 1.4 User Permissions
You need `sudo` access for package installation and SD card mount
operations. The build scripts detect whether they are running as root
or can use passwordless sudo; if neither works, they print the manual
install command and exit.
```bash
sudo -n true 2>/dev/null && echo "passwordless sudo: OK" || echo "passwordless sudo: NO (will prompt)"
```
---
## 2. Cross-Compiler Toolchain
The build requires a `mipsel-linux-musl` cross-compiler targeting
MIPS32r2 little-endian with hard-float ABI and musl libc. The `build.sh`
script and all Makefiles expect the toolchain binaries to be named with
the prefix `mipsel-linux-musl-` (e.g., `mipsel-linux-musl-gcc`,
`mipsel-linux-musl-strip`, `mipsel-linux-musl-ar`,
`mipsel-linux-musl-ranlib`).
### 2.1 Toolchain Source: Rockbox (Recommended)
Rockbox maintains a tested MIPS cross-compiler specifically for Ingenic
JZ47xx and X1000-family SoCs. Since Rockbox has a port for this exact
device family, their toolchain is the most authoritative and
hardware-verified option available.
**Option A: Use Rockbox's prebuilt toolchain**
1. Visit the Rockbox toolchain downloads page:
`https://www.rockbox.org/wiki/CrossCompile`
2. Download the MIPS toolchain tarball.
3. Extract and install:
```bash
sudo mkdir -p /opt/mipsel-linux-musl
sudo tar xzf rockbox-mips-toolchain-*.tar.gz -C /opt/mipsel-linux-musl --strip-components=1
```
4. Add to PATH (see Section 2.4).
**Option B: Build the Rockbox toolchain from source**
```bash
git clone https://github.com/Rockbox/rockbox.git
cd rockbox/tools
# Follow instructions at https://www.rockbox.org/wiki/CrossCompile
```
> Rockbox's toolchain is still the recommended
> cross-compiler even though Rockbox is no longer the recommended
> headers source. The toolchain (compiler + binutils + libc) is
> SoC-agnostic enough that it works for any MIPS32r2 target.
### 2.2 Toolchain Source: musl.cc (Fallback)
If the Rockbox toolchain is unavailable, musl.cc provides
community-built musl cross-compiler binaries. These are generic and not
tuned for Ingenic specifically.
```bash
wget https://musl.cc/mipsel-linux-musl-cross.tgz -O /tmp/mipsel-toolchain.tgz
sudo mkdir -p /opt/mipsel-linux-musl
sudo tar xzf /tmp/mipsel-toolchain.tgz -C /opt/mipsel-linux-musl --strip-components=1
```
**Caveat**: musl.cc toolchains may not include Ingenic-specific compiler
intrinsics or tune flags. If you encounter issues with floating-point
operations or scheduler behavior, switch to the Rockbox toolchain.
### 2.3 Toolchain Source: Buildroot Self-Build (Advanced)
Buildroot can generate a complete cross-compiler toolchain from source.
This is the most flexible option but also the slowest (build time: 15-45
minutes). See Section 4.
### 2.4 Add Toolchain to PATH
```bash
export PATH="/opt/mipsel-linux-musl/bin:$PATH"
mipsel-linux-musl-gcc --version
mipsel-linux-musl-gcc -dumpmachine # Should print: mipsel-linux-musl
```
If your toolchain uses a different prefix, set `CROSS_COMPILE`:
```bash
export CROSS_COMPILE=mips-linux-gnu-
./build.sh
```
### 2.5 Verify the Toolchain Works
```bash
echo '#include <stdio.h>
int main(void) { printf("hello mipsel\\n"); return 0; }' > /tmp/test.c
mipsel-linux-musl-gcc -march=mips32r2 -mhard-float -static -o /tmp/test_mips /tmp/test.c
file /tmp/test_mips
# Expected: ELF 32-bit LSB executable, MIPS, MIPS32 version 1 ...
```
---
## 3. Kernel Headers (FiiO M3K GPL tree)
> **Read [HEADERS.md](HEADERS.md) for the full strategy.** This section
> is a quick-start summary.
OreBolt OS sources kernel headers from the **FiiO M3K GPL kernel tree** (Linux
3.10.14, Ingenic BSP) because the M3K uses the **exact same Ingenic
X1000E SoC as the H2**. The FiiO tree ships the X1000E register
definitions, GPIO mux tables, clock tree headers, and DMA descriptor
formats -- all GPL-2.0, all directly `#include`-able, no reverse
engineering needed.
### 3.1 Install the FiiO M3K kernel tree
```bash
sudo mkdir -p /opt/fiio-m3k-linux
# Clone from a community mirror, or extract FiiO's official GPL tarball:
sudo tar xzf fiio_m3k_kernel_*.tar.gz -C /opt/fiio-m3k-linux --strip-components=1
# Verify
ls /opt/fiio-m3k-linux/include/uapi/linux/kernel.h
ls /opt/fiio-m3k-linux/arch/mips/include/asm/mach-jz4760/jz4760.h
```
### 3.2 Verify with `make headers-check`
```bash
make headers-check KERNEL_HEADERS=/opt/fiio-m3k-linux
# Expected:
# [OK] kernel headers root: /opt/fiio-m3k-linux
```
### 3.3 Fallback: Ingenic XBurst BSP
If a header is missing from the FiiO tree, use the raw Ingenic XBurst
BSP. See [HEADERS.md §3](HEADERS.md#3-ingenic-xburst-bsp-fallback).
### 3.4 What about Rockbox?
Rockbox is now **optional** and scoped to a future bare-metal "OreBolt OS
Native" port. The current Linux userspace build path does not use
Rockbox at all. See [HEADERS.md §4](HEADERS.md#4-rockbox-optional-bare-metal-only).
---
## 4. Optional: Buildroot for X1000E Full Image
Buildroot is not required for the module-level cross-compilation that
`build.sh` performs. However, if you want to produce a complete root
filesystem image for the H2 (kernel + initramfs + rootfs with all
OreBolt OS modules), Buildroot is the right tool.
### 4.1 Clone Buildroot
```bash
git clone https://github.com/buildroot/buildroot.git
cd buildroot
git checkout 2024.02 # or current stable
```
### 4.2 Configure for Ingenic X1000E
```bash
make menuconfig
```
**Target options:**
```
Target Architecture = MIPS (little endian)
Target Architecture Variant = mips32r2
Target ABI = 32 (soft-float) # override below for hard-float
```
**Toolchain:**
```
Toolchain type = External toolchain
Toolchain = Custom toolchain
Toolchain path = /opt/mipsel-linux-musl
Toolchain prefix = $(ARCH)-linux-musl-
```
**Hard-float note**: the X1000E has a hardware FPU. OreBolt OS compiles
with `-mhard-float`. If Buildroot does not expose a hard-float option
in menuconfig, force it via `BR2_TARGET_OPTIMIZATION="-mhard-float"` in
`.config`.
**System configuration:**
```
System hostname = h2-hifiwalker
System banner = Welcome to OreBolt OS
/dev management = Dynamic using devtmpfs
Init system = BusyBox init (SysVinit)
```
### 4.3 Integrate the OreBolt OS Overlay
In menuconfig: System configuration -> Root filesystem overlay directories
Add: `/path/to/h2-workspace/overlay`
Or edit `.config` directly:
```
BR2_ROOTFS_OVERLAY="/path/to/h2-workspace/overlay"
```
### 4.4 Build and Flash
```bash
make
# Output: output/images/{rootfs.ext4, zImage, sdcard.img}
sudo dd if=output/images/sdcard.img of=/dev/sdX bs=4M status=progress
sync
sudo eject /dev/sdX
```
---
## 5. Workspace Clone & Verify
```bash
git clone <repo-url> h2-workspace
cd h2-workspace
```
### 5.1 Verify Workspace Integrity
`build.sh` Phase 2 does this automatically, but you can check manually:
```bash
# Required top-level files
ls -1 Makefile Makefile.h2-core-v6.2 Makefile.orebolt-v1.5 \
build.sh inject_payloads.sh \
main.c include/h2_ui.h include/log_manager.h lv_conf.h.dist \
src/modules/panic_purge_api.h \
PREREQUISITES.md HEADERS.md LICENSE.md CHANGELOG.md \

# Init scripts
ls -1 overlay/etc/init.d/S98retro-input \
overlay/etc/init.d/S99broker \
overlay/etc/init.d/bt_input_daemon.sh
# Hardware library sources (7 files)
ls -1 src/modules/
```
### 5.2 Verify Toolchain
```bash
mipsel-linux-musl-gcc --version
mipsel-linux-musl-gcc -dumpmachine # Must contain "mips"
```
---
## 6. SD Card Preparation
The HiFiWalker H2 boots from an SD card. Minimum: a single FAT32
partition holding the firmware files.
### 6.1 Identify the SD Card
```bash
lsblk -o NAME,SIZE,TYPE,MOUNTPOINT
```
**WARNING**: Be absolutely certain you have identified the correct
device. `/dev/sda` is typically your system disk.
### 6.2 Single-Partition Layout
```bash
sudo umount /dev/sdX1 2>/dev/null || true
sudo parted /dev/sdX --script mklabel msdos
sudo parted /dev/sdX --script mkpart primary fat32 1MiB 100%
sudo parted /dev/sdX --script set 1 boot on
sudo mkfs.vfat -F 32 -n OREBOLT /dev/sdX1
```
### 6.3 Dual-Partition Layout (Full Rootfs)
```bash
sudo parted /dev/sdX --script mklabel msdos
sudo parted /dev/sdX --script mkpart primary fat32 1MiB 129MiB
sudo parted /dev/sdX --script set 1 boot on
sudo parted /dev/sdX --script mkpart primary ext4 129MiB 100%
sudo mkfs.vfat -F 32 -n H2_BOOT /dev/sdX1
sudo mkfs.ext4 -L H2_ROOT /dev/sdX2
```
### 6.4 Deploy
```bash
SD_CARD_MOUNT=/mnt/h2-sd ./build.sh --deploy
```
---
## 7. Environment Variables Reference
| Variable | Default | Description |
|---|---|---|
| `CROSS_COMPILE` | `mipsel-linux-musl-` | Toolchain binary prefix |
| `KERNEL_HEADERS` | `/opt/fiio-m3k-linux` | FiiO M3K GPL kernel tree path |
| `HARDWARE_GPIO` | `0` | Set to `1` only on real H2 hardware to compile real GPIO panic purge |
| `SD_CARD_MOUNT` | `/mnt/h2-sd` | SD card mount point for `--deploy` |
| `NO_COLOR` | (unset) | Set to `1` to disable ANSI color in build scripts |
| `PATH` | (system) | Must include `/opt/mipsel-linux-musl/bin` |
Recommended `~/.bashrc` additions:
```bash
export PATH="/opt/mipsel-linux-musl/bin:$PATH"
export KERNEL_HEADERS="/opt/fiio-m3k-linux"
# export SD_CARD_MOUNT="/run/media/$USER/OREBOLT"
# export HARDWARE_GPIO=0 # explicit on dev host; set to 1 on hardware
```
---
## 8. Troubleshooting
### Toolchain not found
```
[-] Missing toolchain binaries: mipsel-linux-musl-gcc
```
Verify `/opt/mipsel-linux-musl/bin/` is in `$PATH`. If your toolchain
uses a different prefix, set `CROSS_COMPILE`.
### Compiler target is not MIPS
```
[!] Compiler target 'x86_64-linux-gnu' does not look like MIPS
```
Run `which mipsel-linux-musl-gcc` and `mipsel-linux-musl-gcc
-dumpmachine`. Ensure the cross-compiler's `bin/` appears before
`/usr/bin/` in `$PATH`.
### KERNEL_HEADERS not found
```
[-] CRITICAL: KERNEL_HEADERS not found at /opt/fiio-m3k-linux
```
Install the FiiO M3K GPL kernel tree (Section 3.1) or set
`KERNEL_HEADERS` to point at the XBurst BSP fallback (HEADERS.md §3).
### musl.cc toolchain float ABI mismatch
```
error: cannot find -lm
```
or linker errors about `soft-float` vs `hard-float`. Switch to the
Rockbox toolchain (Section 2.1) which is configured for Ingenic's
hard-float ABI.
### LVGL clone fails
```
[*] Cloning LVGL v8.3.11 + lv_drivers v8.3.0...
fatal: unable to access 'https://github.com/lvgl/lvgl.git'
```
Pre-clone LVGL manually:
```bash
git clone --depth 1 -b v8.3.11 https://github.com/lvgl/lvgl.git
git clone --depth 1 -b v8.3.0 https://github.com/lvgl/lv_drivers.git
cp lv_conf.h.dist lv_conf.h
cp lv_drivers/lv_drv_conf_template.h lv_drv_conf.h
sed -i 's/#if 0/#if 1/' lv_drv_conf.h
sed -i 's/USE_FBDEV 0/USE_FBDEV 1/' lv_drv_conf.h
sed -i 's/USE_EVDEV 0/USE_EVDEV 1/' lv_drv_conf.h
```
`build.sh` Phase 5 will detect the existing `lvgl/src/` and skip
cloning.
### bitchat.mod missing AGPL_BITCHAT marker
```
[-] bitchat.mod missing AGPL_BITCHAT marker (license violation)
```
`mod_bitchat_mesh.c` was compiled without `-DAGPL_BITCHAT`. This
should not happen if you build via `make` or `./build.sh` (both set
the define in `Makefile.orebolt-v1.5`). If you are building
manually, add `-DAGPL_BITCHAT` to `CFLAGS`.
### Binary format verification fails
```
[-] BAD: h2_test -- ELF 64-bit LSB executable, x86-64
```
The build picked up the host GCC instead of the cross-compiler. Run
`./build.sh --clean && ./build.sh`.
---
## 9. Licensing
OreBolt OS uses a multi-tier licensing strategy. See
[LICENSE.md](LICENSE.md) for the full strategy.
- **bitchat mesh module**: AGPL-3.0-only
- **All other OreBolt OS modules**: GPL-2.0-or-later
- **LVGL/lv_drivers**: MIT (upstream)
If you modify and deploy bitchat, you MUST make your modified source
available to anyone who interacts with your modified node over the mesh
(AGPL v3 §13). Replace the `BITCHAT_SOURCE_URL` placeholder in
`mod_bitchat_mesh.c` with your real Written Offer URL before deploying.
---
## 10. What `build.sh` Handles Automatically
| Phase | What It Does | You Need To... |
|---|---|---|
| 0 | Checks for `base-devel`, `git`, `make`, `python3`, SD utils; probes for `KERNEL_HEADERS` | Install host deps + FiiO M3K kernel tree (Sections 1, 3) |
| 1 | Verifies `mipsel-linux-musl-{gcc,strip,ar,ranlib}` exist and target MIPS | Install the toolchain (Section 2) |
| 2 | Validates all 18 module source files, init scripts, and required top-level files | Clone the workspace (Section 5) |
| 3 | Creates the `overlay/` directory tree (apps/, usr/lib/, usr/bin/, etc.) | Nothing |
| 4 | Sets executable permissions on init scripts and utility scripts | Nothing |
| 5 | Builds H2 Core v6.2: clones LVGL/lv_drivers, compiles liblvgl.so, h2_test launcher, 18 modules, input mapper | Have network access (or pre-clone LVGL) |
| 6 | Builds OreBolt OS: compiles liborebolt.a and generates 150-payload matrix | Nothing |
| 7 | Verifies all artifacts exist, checks MIPS LE ELF, verifies bitchat AGPL marker | Nothing |
| 8 | Copies everything to SD card mount point, creates ROM directories | Mount SD card (Section 6) |
**In summary, you only need to do Sections 1, 2, 3, 5, and 6 before
running `./build.sh`.** Section 4 (Buildroot) is optional and only
needed for producing a full rootfs image.

# OreBolt OS -- Quickstart
Build and deploy OreBolt OS to a HiFiWalker H2 (or compatible rebadged DAP)
from a fresh Arch Linux host. ~30 min if toolchain and kernel tree are
pre-staged, ~75 min if building the toolchain from source.
> **Not on Arch?** Stop. The build pipeline is validated against Arch only.
> Other distros will need porting effort. See [PREREQUISITES.md](PREREQUISITES.md)
> section 1 for the full dependency rationale.
---
## 0. What you need
| Item | Where | Details |
|---|---|---|
| Arch Linux host (x86_64) | any Arch install | `pacman -Syu` first |
| `mipsel-linux-musl` toolchain | Rockbox prebuilt tarball (recommended) | step 2 below |
| FiiO M3K GPL kernel tree | community mirror or FiiO's GPL download | step 3 below |
| MicroSD card, 2 GB or larger | any | FAT32, single partition |
---
## 1. Host dependencies
```bash
sudo pacman -Syu --needed base-devel git make python3 rsync \
dosfstools e2fsprogs parted file
```
## 2. Cross toolchain
Option A — Rockbox prebuilt (recommended, ~5 min):
```bash
sudo mkdir -p /opt/mipsel-linux-musl
sudo tar xzf rockbox-mips-toolchain-*.tar.gz \
-C /opt/mipsel-linux-musl --strip-components=1
```
Option B — musl.cc fallback (less tuned, but works):
```bash
wget https://musl.cc/mipsel-linux-musl-cross.tgz -O - | \
sudo tar xz -C /opt/mipsel-linux-musl --strip-components=1
```
Either way, add to PATH and verify:
```bash
export PATH="/opt/mipsel-linux-musl/bin:$PATH"
echo 'export PATH="/opt/mipsel-linux-musl/bin:$PATH"' >> ~/.bashrc
mipsel-linux-musl-gcc -dumpmachine
# expected output: mipsel-linux-musl
```
## 3. Kernel headers
The FiiO M3K uses the same Ingenic X1000E SoC as the H2, so its GPL kernel
tree is the canonical headers source — no reverse-engineering from Rockbox
needed. See [HEADERS.md](HEADERS.md) for mirror URLs and the XBurst BSP
fallback path.
```bash
sudo mkdir -p /opt/fiio-m3k-linux
sudo tar xzf fiio_m3k_kernel_*.tar.gz \
-C /opt/fiio-m3k-linux --strip-components=1
export KERNEL_HEADERS=/opt/fiio-m3k-linux
echo 'export KERNEL_HEADERS=/opt/fiio-m3k-linux' >> ~/.bashrc
make headers-check
# expected output: [OK] kernel headers root: /opt/fiio-m3k-linux
```
## 4. Build
```bash
git clone <your-repo-url> h2-workspace
cd h2-workspace
./build.sh
```
The build script runs eight phases in sequence:
| Phase | What it does |
|---|---|
| 0–1 | Verifies host deps, toolchain, and kernel headers |
| 2 | Workspace integrity check (all modules + headers + scripts present) |
| 3–4 | Creates `overlay/` tree, fixes permissions |
| 5 | Clones LVGL v8.3.11, builds `liblvgl.so`, `h2_test`, all modules, mapper |
| 6 | Builds `liborebolt.a`, regenerates 150-payload HID matrix |
| 7 | Validates all artifacts are MIPS LE ELF; checks bitchat AGPL marker |
| 8 | *(only with `--deploy`)* Copies everything to SD card |
## 5. Verify the build
```
[OK] OREBOLT OS v1.7 BUILD COMPLETE
```
Artifacts you should see on disk:
| Artifact | Path | Notes |
|---|---|---|
| `liblvgl.so` | `overlay/usr/lib/` | LVGL v8.3.11 shared library (MIT) |
| `h2_test` | `overlay/usr/bin/` | Master launcher |
| `retro_input_mapper` | `overlay/usr/bin/` | Gamepad input mapper daemon |
| 17 `*.mod` files | `overlay/apps/` | 16 GPL modules + 1 AGPL bitchat |
| `liborebolt.a` | `./` | Hardware library static archive |
| 150 `.dd` payloads | `overlay/data/payloads/{linux,macos,windows}/` | HID macro matrix |
Confirm a binary is actually MIPS, not accidentally built with host GCC:
```bash
file overlay/usr/bin/h2_test
# expected: ELF 32-bit LSB executable, MIPS, MIPS32 version 1 ...
```
## 6. Deploy to SD card
```bash
# Identify the card (be sure — /dev/sda is usually your system disk)
lsblk -o NAME,SIZE,TYPE,MOUNTPOINT
# Format: single-partition FAT32
sudo umount /dev/sdX1 2>/dev/null || true
sudo parted /dev/sdX --script mklabel msdos
sudo parted /dev/sdX --script mkpart primary fat32 1MiB 100%
sudo parted /dev/sdX --script set 1 boot on
sudo mkfs.vfat -F 32 -n OREBOLT /dev/sdX1
# Mount and deploy
sudo mkdir -p /mnt/h2-sd
sudo mount /dev/sdX1 /mnt/h2-sd
SD_CARD_MOUNT=/mnt/h2-sd ./build.sh --deploy
sync && sudo umount /mnt/h2-sd && sudo eject /dev/sdX
```
Insert the card, power on the H2. The LVGL UI boots with all 17 modules
registered. Init order: `S98retro-input` → `S99broker` (starts
`h2_test`) → `bt_input_daemon.sh` (BLE).
---
## Troubleshooting
| Symptom | Fix |
|---|---|
| `[-] Missing toolchain binaries: mipsel-linux-musl-gcc` | `export PATH="/opt/mipsel-linux-musl/bin:$PATH"` |
| `[-] CRITICAL: KERNEL_HEADERS not found` | Install FiiO M3K GPL tree (step 3) |
| `[-] BAD: h2_test -- ELF 64-bit LSB executable, x86-64` | `./build.sh --clean && ./build.sh` (host GCC leaked in) |
| `error: cannot find -lm` | Switch to Rockbox toolchain (step 2, option A) |
| `fatal: unable to access 'https://github.com/lvgl/lvgl.git'` | Pre-clone LVGL manually (see PREREQUISITES.md section 8) |
| `[-] bitchat.mod missing AGPL_BITCHAT marker` | If building manually, add `-DAGPL_BITCHAT` to CFLAGS |
---
## Before deploying bitchat (AGPL obligation)
If you modify the bitchat module and deploy it where other operators will
interact with it over the mesh, AGPL v3 section 13 requires you to provide
your modified source. Do this before deploying:
```bash
# 1. Replace the placeholder URL with your real source / Written Offer
sed -i 's|https://example.invalid/orebolt-bitchat-src|https://your-domain/orebolt-os-bitchat-src|' \
src/modules/mod_bitchat_mesh.c
# 2. Drop in the full AGPL license text
curl -o licenses/AGPL-3.0.txt https://www.gnu.org/licenses/agpl-3.0.txt
# 3. Rebuild
./build.sh --clean && ./build.sh
```
Full compliance checklist: [LICENSE.md section 4](LICENSE.md#4-operator-obligations-when-modifying-bitchat).

# OreBolt OS
A hackable firmware for the HiFiWalker H2 — a $30 MIPS digital audio player
that ships with a Linux userspace, a 320×320 LCD, and 64 MB of RAM.
> **New here?** Jump to [QUICKSTART.md](QUICKSTART.md) for the build-and-deploy
> walkthrough. This document is the project reference.
There is a particular class of consumer hardware that is cheap enough to be
disposable, yet capable enough to run a real operating system with real
peripherals. The HiFiWalker H2 sits squarely in that class. Under its
rubberized shell is an Ingenic X1000E SoC — a MIPS32r2 hard-float core
clocked at ~1.0 GHz, paired with 64 MB of DDR2 and an ESS ES9018K2M DAC that
was designed for serious audio. The stock firmware plays music. OreBolt OS
replaces it with a modular, LVGL-driven toolkit for hardware interrogation,
RF sensing, payload delivery, and forensic extraction — all running on a
device that fits in a shirt pocket and boots from a FAT32 MicroSD card.
The entire system is cross-compiled from an Arch Linux host using a
`mipsel-linux-musl` toolchain (the Rockbox prebuilt is recommended). Every
user-facing module is a single-position-independent `.mod` ELF binary that
dynamically links against a shared `liblvgl.so`. A fork/exec broker in the
master launcher (`h2_test`) loads them on demand, which means only one module's
code segment lives in RAM at a time — a hard constraint when your whole
working set is 64 MB and the kernel already claims its cut.
See [CHANGELOG.md](CHANGELOG.md) for the version history.

## The H2 hardware family
The H2 is one of five rebadged DAPs built on the same PCB. They are
interchangeable from a firmware perspective.
| Brand / Model | Notes |
|---|---|
| HiFiWalker H2 | Most widely known; rubberized scroll wheel |
| Surfans F20 | Knurled metal scroll wheel |
| Aigo Eros Q | Original design base for the family |
| Phinistec Z6 | Common rebadged version |
| Agptek H3 | Same lineage of budget DAPs |
All share the X1000E SoC, ESS ES9018K2M DAC, and MAX97220 headphone amp.
Multiple hardware revisions exist — some have Micro-USB, newer ones have
USB-C. All are Rockbox-compatible, and all run the same OreBolt OS image.
## Architecture at a glance
The build pipeline is a single `./build.sh` invocation with eight phases:
dependency verification, workspace integrity check, overlay tree creation,
LVGL compilation, module compilation, hardware library archiving, artifact
validation (MIPS ELF + AGPL marker check), and optional SD card deployment.
The Makefile is split into a thin `Makefile` shell that delegates to
`Makefile.h2-core-v6.2`, which knows how to build the core runtime, LVGL,
and all modules in the correct dependency order.
At runtime the flow is: init scripts start the retro input mapper daemon
(`S98retro-input`), then the master launcher (`S99broker` / `h2_test`),
then the BLE input daemon. The launcher presents a scrollable LVGL menu of
all registered modules. Selecting one causes the broker to `fork()` + `execv()`
the corresponding `.mod` binary from `overlay/apps/`. When the module exits,
control returns to the launcher menu. Only one module runs at a time.
The platform ships three core artifacts besides the modules themselves:
`liblvgl.so` (LVGL v8.3.11, ~200 KB, MIT-licensed upstream), `liborebolt.a`
(a static archive of hardware-level routines linked into every module), and a
150-payload HID macro matrix split across Linux, macOS, and Windows profiles.
## Modules
Seventeen modules, each a self-contained `.mod` binary with its own LVGL
screen. They group into four operational categories plus one networking
module with a separate license tier.
### Offense / payload delivery
These modules exist because the H2's USB port can be reconfigured into
arbitrary gadget topologies through ConfigFS. That single capability —
presenting the device as whatever USB composite the operator needs — is the
foundation of the offense surface.
**`deploy.mod`** — Flash storage manager. Calls `statvfs("/")` to pull
total, used, and free bytes from the SD card and renders them as a live
storage dashboard. The PLAY button triggers a manual `sync()` flush. Not
exciting on its own, but every operator needs to know how much space is left
before dropping a 150-payload macro matrix onto a 2 GB card.
**`pauto.mod`** — Payload Automation, the HID keystroke injector. It parses
OreBolt's custom macro command language and injects keystrokes through
`/dev/hidg0`, the HID function endpoint exposed by the gadget subsystem.
Each `.dd` payload file encodes an OS-specific key sequence (delay, modifier,
scan code triples). The module selects the correct profile (Linux, macOS, or
Windows) and plays it back at USB-speed. This is the module that turns the H2
from a music player into a BadUSB-class device.
**`retro.mod`** — Retro game launcher. Scans `/data/roms/` recursively
for ROM files across 11 systems (NES, SNES, Game Boy, Genesis, SMS,
GameGear, PCE, Atari 2600, Neo Geo Pocket, and FDS/GBA), auto-detects the
target system by file extension, and displays a filterable LVGL picker
menu. Selecting a ROM forks the matching emulator binary (fceux, snes9x,
gambatte, gpsp, dgen, mednafen, or stella) and monitors it — BACK sends
SIGTERM to the emulator child. The companion `retro_input_mapper` daemon
runs at boot via `S98retro-input` and creates a virtual uinput gamepad
that maps the H2's rotary encoder and buttons to standard d-pad + ABXYLR
+ Start/Select, complete with a rotary-press axis toggle (vertical U/D
vs. horizontal L/R) that auto-reverts after 3 seconds of idle.
**`glitch.mod`** — Hardware glitch injector. Drives X1000E GPIO lines to
produce timed power and clock glitches against an externally-wired target.
The module exposes controls for glitch width, trigger delay, and repeat count
on the LVGL UI. It is the most hardware-dependent module in the stack — it
requires physical access to the target's power or clock rail and assumes the
operator has wired the glitch circuit correctly.
### Forensics & extraction
**`extract.mod`** — Mass storage extractor. Recursively copies files from
`/mnt/target_media` (a mount point for an attached USB mass storage device)
into `/data/loot_drop/extracted/`. It walks the directory tree, skips
symlinks (to avoid following loops into the host filesystem), copies in 4 KB
chunks, and displays running file, directory, and byte counts on the LVGL
screen. The forensic dispatch engine that selects which `.dd` payload to run
against a detected OS lives in `mod_forensics.c` within `liborebolt.a`.
**`vault.mod`** — Encrypted credentials and payload vault. Provides PIN-based
authentication and stores operator-curated quick-launch lists in
`Provision.txt`. Sensitive payload content is encrypted at rest. The vault
is the module you lock down before handing the device to someone else.
**`probe.mod`** — I2C bus scanner. Probes `/dev/i2c-0` across the full
address space (0x03–0x77) using `ioctl(I2C_SLAVE)` + `i2c_smbus_read_byte()`.
Responding devices are highlighted green on the LVGL display. On the H2 this
will typically enumerate the DAC, the audio codec, and any attached I2C
peripherals. Five seconds of runtime tells you exactly what is on the bus.
**`pwdb.mod`** — Password database with bcrypt and argon2 verification.
Stores operator-managed credential entries and supports verifying captured
hashes against the local database. The hashing implementations are linked
from `liborebolt.a` and run entirely on the MIPS core — no external crypto
library dependency.
### Reconnaissance & sensing
This is where the H2's Bluetooth radio and its (future) WiFi capability come
into play. The X1000E has an on-die BLE controller, and the recon
architecture supports WiFi scanning through `nl80211` once a driver is
available.
**`proxalarm.mod`** — The flagship recon module, built as a single `.mod`
binary with three internal layers to keep the RAM footprint tight on a 64 MB
device:
The **bledsp** layer handles RF scanning. It opens the BLE socket, pulls
advertisements, and runs the RSSI values through a rolling-average low-pass
filter implemented with MIPS DSP ASE intrinsics (`__builtin_mips_q31` mul
and shift operations) to smooth out the noise floor. A `bledsp_poll_wifi()`
stub is wired in and ready for future `nl80211` integration — when a WiFi
driver lands, the same smoothing pipeline handles WiFi RSSI with no
architectural change. The **NEXT** key cycles the RF source between BLE and
WiFi.
The **proxvec** layer is the kinematics engine. It maintains a target table
with unique device IDs, tracks per-target state machines (new / tracking /
stale / expired), and computes radial velocity from the rate of change in
smoothed RSSI over time (delta-distance divided by delta-time). This is not
GPS-accurate positioning — it is coarse proximity estimation based on RF
signal propagation, but on a device the size of a deck of cards, coarse is
what you get and coarse is useful.
The **radar_ui** layer renders a 320×320 LVGL canvas with a rotating sweep
line, four range rings, and color-coded blips for each tracked target. Blip
color encodes signal strength (bright green for close, dim red for far), and
velocity vectors show whether a target is approaching or receding. When a
target crosses the alarm threshold, the display flashes an overlay. The
**ROTATE** knob cycles through four sensitivity presets (−40 to −70 dBm
floor), **PLAY** toggles pause/resume, **BACK** exits.
One binary, one scan loop, one set of smoothing buffers — the entire
proximity sensing pipeline fits in a single module slot.
**`nettaps.mod`** — USB virtual network tap. Opens a raw `AF_PACKET` socket
on `usb0`, captures IP packets, and parses them into a live LVGL console. A
configurable time-window coalescer (30 s / 1 min / 2 min / 5 min / 10 min)
aggregates packet counts before flushing to disk — important because the H2's
SD card has limited write endurance. The flash-safe timed flush is the detail
that separates a toy packet sniffer from something you can leave running on
actual hardware.
**`rfid.mod`** — RFID/NFC reader. Drives an externally-attached reader over
UART or SPI, enumerates cards in range, and dumps tag memory contents to the
LVGL display. The module itself is straightforward; the complexity lives in
the physical layer — which reader board, which antenna, which frequency band
(125 kHz LF or 13.56 MHz HF).
### Environment & shell
**`vterm.mod`** — Virtual terminal with a FreeDOS bridge. Provides a
TTY-style shell rendered inside an LVGL text area. Ships a minimal FreeDOS
userland under `overlay/data/vterm/freedos/bin/` for x86 emulation scenarios.
On the H2's MIPS core this is necessarily slow, but it demonstrates that the
module system can host an entire foreign userland.
**`studio.mod`** — UAC2 Mixer Console. Four-channel mixer (GAME / DISCORD /
MIC / MUSIC) with per-channel volume bars. **NEXT** and **PREV** cycle the
active channel, **PLAY** toggles hardware mute. Volume adjustments are sent
as USB Consumer Control HID commands through `/dev/hidg1`. The module turns
the H2 into a physical audio mixer — plug it into a host, twist the scroll
wheel, and the host's volume changes.
**`noise.mod`** — True random number generator. Pulls 32-byte entropy blocks
from the kernel via `getrandom(GRND_RANDOM)` and pipes them to the host over
CDC ACM serial (`/dev/ttyGS0`) at 100 Hz. The entropy source is the hardware
TRNG on the X1000E, not a software PRNG — the output is suitable for
cryptographic seeding.
**`reset.mod`** — Factory reset and purge coordinator. The operator-facing
front-end for the panic-purge subsystem. It invokes `mod_panic_purge`
(software: zeroes RAM caches, temp files, and `/data/vault/syslog.log`) and
then `mod_panic_hardware_purge` (hardware: cuts SD card slot power and shorts
SPI flash write-protect via X1000E GPIO) in the correct sequence. The
hardware purge is a compile-time toggle (`HARDWARE_GPIO=0` for stubs,
`HARDWARE_GPIO=1` for real GPIO manipulation).
### Networking
**`bitchat.mod`** — Mesh chat, and the only module under AGPL-3.0-only. An
independent C implementation of the BitChat wire protocol — not affiliated
with, sponsored by, or endorsed by Permissionless Tech, LLC. The name is
used under nominative fair use (see [LICENSE.md](LICENSE.md) section 8). It
implements the full `BITCHAT_MSG_*` message type set, advertises its Written
Offer URL on every mesh HELLO via `BITCHAT_MSG_LICENSE`, and uses
`mod_radio_input_multiplex` (BLE + LoRa + 433 MHz) as its transport layer.
The mesh implementation itself lives in `mod_bitchat_mesh.c` within
`liborebolt.a`, compiled with a mandatory `-DAGPL_BITCHAT` flag — the build
fails without it, enforced in `build.sh` Phase 7.
## Hardware library (`liborebolt.a`)
A static archive linked into every `.mod` binary. Source lives under
`src/modules/`. These are the low-level routines that modules call but do
not implement themselves.
| File | Purpose |
|---|---|
| `mod_core_hid.c` | HID descriptor tables shared by `pauto.mod` and `retro.mod` |
| `mod_forensics.c` | Forensic extraction engine — dispatches `.dd` payloads by OS profile |
| `mod_panic_purge.c` | Software panic purge — zeroes volatile state before hardware purge |
| `mod_panic_hardware_purge.c` | Hardware panic purge — GPIO-driven SD power cut and SPI flash WP |
| `mod_radio_input_multiplex.c` | Radio input multiplexer (BLE + LoRa + 433 MHz); bitchat transport |
| `mod_ui_frame_graphics.c` | RGB565 blitters, double-buffer management, scroll wheel routing |
| `mod_bitchat_mesh.c` | BitChat mesh networking (AGPL-3.0-only; `-DAGPL_BITCHAT` required) |

* retro.c -- OreBolt OS Module: Retro Game Launcher
*
* SPDX-License-Identifier: GPL-2.0-or-later
*
* Scans /data/roms/ for ROM files, auto-detects the target system by
* file extension, displays an LVGL picker menu, and launches the
* matching emulator binary via fork()+execv(). Standalone .mod
* binary with its own main() and LVGL init.
*
* Supported systems (by file extension):
* .nes - Nintendo Entertainment System
* .fds - Famicom Disk System
* .smc,.sfc,.fig - Super Nintendo (SNES)
* .gb - Game Boy
* .gbc - Game Boy Color
* .gba - Game Boy Advance
* .smd,.md,.bin,.gen - Sega Genesis / Mega Drive
* .sms - Sega Master System
* .gg - Sega Game Gear
* .pce - PC Engine / TurboGrafx-16
* .a26 - Atari 2600
* .ngp,.ngc - Neo Geo Pocket / Color
*
* Emulator binaries must be installed at the paths listed in
* rom_types[] below.
*
* INPUT MAPPING:
* The companion retro_input_mapper daemon (started by S98retro-input
* at boot) creates a virtual gamepad via uinput. Emulators should
* read from this virtual gamepad rather than /dev/input/event0.
*
* D-pad: Rotary CW/CCW with axis toggle (rotary press switches
* between vertical U/D and horizontal L/R modes, auto-
* reverts to V-mode after 3s idle).
* A: PLAY short press (confirm/jump/shoot)
* B: BACK short press (cancel/run)
* START: PLAY long press (1.5s)
* SELECT: BACK long press (1.5s)
* L/R: Side buttons PREV(165) / NEXT(163)
* X/Y: Combo buttons (PLAY+rotate / BACK+rotate)
*
* N64 is NOT supported -- the X1000E MIPS32r2 @ ~1 GHz with 64 MB RAM
* cannot run N64 emulation at playable framerates.
*
* Toolchain: mipsel-linux-musl-gcc (MIPS32r2, musl libc)

/*
* retro_input_mapper.c -- H2 Gamepad Input Translator Daemon
*
* Translates the HiFiWalker H2's physical controls into a standard
* Linux gamepad (uinput) that emulators can read natively.
*
* Creates /dev/input/js0 (or next available) as a virtual gamepad
* with: d-pad (4-way), 6 action buttons (A B X Y L R), Start, Select.

* H2 Physical Virtual Gamepad Notes
* -------------- ---------------- -----
* Rotary CCW D-pad Up / Left Axis toggled by rotary click
* Rotary CW D-pad Down / Right
* Rotary press (EV_KEY) Toggle d-pad axis V-mode(U/D) ↔ H-mode(L/R)
* PLAY (164) short A (BTN_SOUTH) Confirm / jump / shoot
* PLAY (164) long 1.5s START (BTN_START) Pause / menu
* BACK (158) short B (BTN_EAST) Cancel / run
* BACK (158) long 1.5s SELECT (BTN_SELECT) In-game menu
* PREV (165) L (BTN_TL) Shoulder left
* NEXT (163) R (BTN_TR) Shoulder right
* (rotary+PLAY combo) X (BTN_NORTH) Context action
* (rotary+BACK combo) Y (BTN_WEST) Context action
*
* When the d-pad is in V-mode (default):
* Rotary CW = D-pad Down
* Rotary CCW = D-pad Up
* Left/Right = hold rotary-click + rotate
*
* When the d-pad is in H-mode (after rotary click):
* Rotary CW = D-pad Right
* Rotary CCW = D-pad Left
* Up/Down = hold rotary-click + rotate
*
* Auto-revert: d-pad returns to V-mode after 3 seconds of no
* rotary activity (prevents stuck in H-mode).
*
* ================================================================
* USAGE
* ================================================================
*
* This daemon should be started by the init system BEFORE any
* emulator is launched. It reads /dev/input/event0 (the H2's
* physical input) and writes to the virtual uinput gamepad.
*
* Emulators should be configured to read from the uinput gamepad
* device rather than /dev/input/event0 directly.
*
* The daemon exits cleanly on SIGTERM or SIGINT.
*
* Build: mipsel-linux-musl-gcc -o retro_input_mapper \
* retro_input_mapper.c

# OreBolt OS v1.4 -- provisioning payload manifest
# ---------------------------------------------------------------------------
# Referenced by the Vault module's deploy.mod subsystem as the default
# automation-routine manifest. Each non-comment, non-blank line is treated
# as a single HID macro entry-point name (without extension) that deploy.mod
# looks up under /data/payloads/<name>.macro or <name>.dd at injection time.
#
# The full 150-payload OreBolt OS matrix is generated at build time by
# inject_payloads.sh and lands in /data/payloads/{linux,macos,windows}/.
# This Provision.txt file is the curated short-list that an operator wants
# hot-loaded into the deploy.mod quick-launch menu.
#
# v1.4: macos/ and windows/ now actually exist (50 .dd each) -- the v1.3
# gap noted in the original file is fixed. See CHANGELOG.md.
#
# Edit this file on the device to reorder the quick-launch list; deploy.mod
# re-reads it on every menu render.
