# Technician tool v0.7 - changes
|
|
|
|
## Serial reading (firmware 1.0.16+, see firmware-diagnostics-what-changed.md)
|
|
- `KOTA: <record> key=value` lines are parsed into fields (`core/logline.py`, kind `KOTA`) and interpreted
|
|
directly by the engine (`diag/engine.py` `_kota_*`, knowledge in `diag/kota.py`) instead of regex rules:
|
|
boot, i2c, rtc, sd, matter, mic, health, status, led, restart.
|
|
- Exact status LED (colour + pattern + meaning) from `led` lines; `status` lines give the reason and a
|
|
status finding that is resolved when the status changes. Cyan LED supported.
|
|
- Restart cause from `last_restart=` / `restart reason=`; state before a restart from `led previous_boot`.
|
|
- Error IDs `[E-XX-NN]`: looked up in `diag/error_ids.csv` (copy of the firmware's docs/error_ids.csv);
|
|
shown with the technician action. Old message rules still match (ID prefix is stripped for matching).
|
|
- Diagnosis panel: new "Box self-report" section; log view filter "KOTA diagnostics + errors".
|
|
- Matter QR dialog uses the exact QR/manual code reported by the box.
|
|
- Older firmware (v1.0) is still diagnosed as before.
|
|
|
|
## Flashing
|
|
- Only `.bin` files in the tool's `firmware/` folder can be flashed (import / developer library removed,
|
|
no manifest needed). The list shows the compile date read from the firmware itself, newest first.
|
|
- "Refresh list" and "Open firmware folder" buttons; broken or duplicate files are listed as "Not offered".
|
|
- Flash verification compares the 8-digit build hash from the `KOTA: boot` line.
|
|
|
|
Note: the KOTA lines are tested against lines built from the firmware source; the firmware has not yet
|
|
been confirmed on hardware.
