Si4684Driver::getPartInfo()/getSysState() existed but were never called, so their byte-offset bugs never surfaced. Wired them into a boot-time diagnostic log (part number, firmware revision, active image, streamed blob byte counts) to check whether the loaded DAB/FM firmware images are genuine and intact, as an alternative explanation to the QFN exposed-pad hardware hypothesis. Fixed two rounds of off-by-one bugs found while doing this: the fields were initially read one byte too far right (e.g. firmwareBuild was reading a flag byte, not a version number); the first fix undershot in the other direction by not accounting for readRaw()'s one-byte SPI lead-in before STATUS0 (already documented and confirmed elsewhere in this file, in pollStc()) -- caught because the "fixed" GET_SYS_STATE reported image=192 (0xC0), the exact signature of STATUS3 with PUP_STATE=3 seen throughout this investigation. All three response buffers were already sized for the lead-in byte, which confirmed the correct fix. Verdict, captured live: blob streamed bytes match local file sizes exactly (no truncation), GET_SYS_STATE reports image=2 (DAB active, correct), GET_PART_INFO reports part=4684 (matches expected Si4684 part number) with a plausible firmware revision -- the loaded DAB firmware is genuine and intact. This closes the last plausible firmware-side explanation for the FM/DAB no-lock symptom; docs/si4684-rf-investigation-report.md and docs/TODO.md (P4/H5) updated with the full record and verdict. Also noted, not yet fixed: BT1035 AT-init now fails deterministically on every boot (was a one-off earlier this session) -- see report's Open Items.

# TODO — DigiRadio firmware
|
||
|
||
Agent task list and hardware-in-the-loop backlog. Working directory for all
|
||
commands is `Software/`.
|
||
|
||
**Current firmware:** `0.8.5` — BT1035 I2S slave boot init, dual OTA + DSP blob updates, EEPROM identity,
|
||
NVS + flash encryption (dev mode), tabbed Web UI with System uploads, CI gate
|
||
(4 jobs).
|
||
|
||
**Before writing code, read `AGENTS.md`, `.cursor/rules/`, and
|
||
`instructions.md`.** Definition of Done: Apache header, doc blocks,
|
||
`doxygen Doxyfile` exits 0, host tests pass, `check-manual-sync.py` and
|
||
`check_si4684_blobs.py` pass, no plaintext secrets.
|

|
||
## Completed agent tasks (T1–T12, fw 0.7.1–0.8.5)
|
||
|
||
| Task | Version | Summary |
|
||
|------|---------|---------|
|
||
| **T1** | 0.7.1 | Doxygen warnings cleared |
|
||
| **T2** | 0.7.1 | CI workflow (host tests, Doxygen, manual sync) |
|
||
| **T3** | 0.7.2 | Preset reorder API/UI, DAB playing ids in status |
|
||
| **T4** | 0.8.0 | RDS/DLS broadcast metadata |
|
||
| **T5** | 0.8.1 | `IntegrationService` — startup, preset recall, last-preset NVS |
|
||
| **T6** | 0.8.2 | Tabbed configuration Web UI (REST coverage) |
|
||
| **T7** | 0.8.2 | Si4684 blob policy — gitignore, docs, `check_si4684_blobs.py` |
|
||
| **T8** | 0.8.3 | NVS + flash encryption — `initEncryptedStorage`, security docs |
|
||
| **T9** | 0.8.4 | Dual-OTA partition table + `dsp` blob slot, rollback Kconfig |
|
||
| **T10** | 0.8.4 | EEPROM EUI-48 identity — SoftAP/BT/hostname/serial |
|
||
| **T11** | 0.8.4 | Updatable ADAU1701 program — `POST /api/dsp/program`, DRAD blob |
|
||
| **T12** | 0.8.4 | ESP32 OTA — `POST /api/system/ota`, rollback confirm on boot |
|
||
|
||
**0.8.5** (hardware/doc alignment): BT1035 boot uses `AT+AUXCFG=3` +
|
||
`AT+I2SCFG=67` (I2S from ADAU1701, not Line-In); I2C pull-ups R1/R16
|
||
confirmed 2\,kΩ; `Hardware/DATASHEET/` bundle + manual cross-refs.
|
||
|
||
Also landed (not numbered): BT1035 pairing (`BluetoothService`), station presets
|
||
(fw 0.7.0), companion-chip boot (Slice 3), ADAU1701 runtime (Slice 5).

## P4 — Hardware-in-the-loop (when PCB arrives)
|
||
|
||
Manual validation only — does not block host CI.
|
||
|
||
### H1. Encrypted NVS boot path
|
||
Follow [`docs/security-flash-nvs.md`](security-flash-nvs.md): first flash with
|
||
`idf.py erase-flash flash`, verify boot logs, Wi-Fi provisioning survives
|
||
reboot, presets and `last_preset` survive power cycle.
|
||
|
||
### H2. End-to-end listening
|
||
Si4684 DAB/FM tune, ADAU1701 profile apply, BT1035 A2DP to headphones,
|
||
now-playing metadata in UI and `/api/tuner/status`.
|
||
|
||
### H3. OTA and DSP program update (on hardware)
|
||
Push a known-good `.bin` via `POST /api/system/ota`, confirm rollback after a
|
||
deliberately bad image. Upload a DRAD blob via `POST /api/dsp/program` and
|
||
verify ADAU replay after reboot.
|
||
|
||
### H4. Production flash encryption (optional)
|
||
After H1 passes, trial build with `sdkconfig.defaults.production` overlay on
|
||
a sacrificial unit; confirm RELEASE mode policy before shipping.
|
||
|
||
### H5. Si4684 FM/DAB no-lock — blob integrity checked, verdict: hardware
|
||
**Verdict (2026-08-13): blob OK → suspect U6 RF ground (re-open PCBWay)**, not
|
||
a firmware/blob defect. Full investigation, evidence, and the two byte-offset
|
||
bugs found/fixed while verifying this: [`docs/si4684-rf-investigation-report.md`](si4684-rf-investigation-report.md).

|
||
## Open firmware polish (non-blocking)
|
||
|
||
Done in fw 0.8.5 unless noted:
|
||
|
||
- BT1035 boot — I2S slave init (`AT+AUXCFG=3`, `AT+I2SCFG=67`) per PCB routing (0.8.5).
|
||
- FM seek down — `POST /api/tuner/seek` with `{"direction":"down"}` (0.8.4).
|
||
- BT1035 — query/set name, paired list (`AT+PLIST`), auto-reconnect
|
||
(`AT+AUTOCONN`) per Feasycom BT1035 manual (0.8.4).
|
||
- Si4684 — `STOP_DIGITAL_SERVICE` (0x82) before FM band switch when DAB
|
||
audio is active; ensemble metrics remain via `DAB_DIGRAD_STATUS` in status (0.8.4).
|
||

|
||
## Quality gates (run from `Software/` before merge)
|
||
|
||
```bash
|
||
cmake -S components/core/test -B build-host && cmake --build build-host
|
||
ctest --test-dir build-host --output-on-failure
|
||
doxygen Doxyfile
|
||
python3 tools/check-manual-sync.py
|
||
python3 tools/check_si4684_blobs.py
|
||
```
|
||
|
||
After editing the web UI: `tools/gzip-www.sh`.

||
## Notes for the agent
|
||
|
||
- Extend existing patterns (`AudioProfile` / `IAudioProfileStore` shape).
|
||
- Never invent Si4684 opcodes — cite AN649.
|
||
- Never invent BT1035 AT strings — cite Feasycom BT1035 programming guide.
|
||
- One logical change per commit; 50/72 messages.
|
||
- Update `ch-classes.tex` / `ch-api.tex` when public API or HTTP changes.
