# Self-contained T2G seat-controller firmware
|
|
|
|
`Seat_Controller_demo/` is the repository-owned IAR project used by the real
|
|
seat-bench executor. It contains the 2026-07-30 heater, ventilation, four-axis
|
|
time/position motion, SMV8 position memory, Hall feedback and ADC
|
|
current-diagnostic code.
|
|
|
|
`Passenger_Seat_Timed_Controller_demo/` is the separately buildable
|
|
passenger-seat variant. Its CAN application exposes four-axis timed movement
|
|
only; position, homing, calibration, dynamic-mode and thermal commands are not
|
|
linked into the application. See its `Docs/README_Passenger_Seat_Timed_Controller.md`
|
|
for the command contract and generated HEX identity (`PST1`).
|
|
|
|
The matching Cypress 7.9.0 build dependencies are vendored beside it:
|
|
|
|
```text
|
|
firmware/t2g/
|
|
├── common/
|
|
├── tviibh8m/
|
|
├── Seat_Controller_demo/
|
|
└── Passenger_Seat_Timed_Controller_demo/
|
|
```
|
|
|
|
This preserves the IAR project's `../../common` and `../../tviibh8m` paths and
|
|
removes any dependency on the original Desktop SDK directory. The applicable
|
|
vendor terms are retained in `CYPRESS_SDK_LICENSE.txt`. An IAR installation is
|
|
still a toolchain prerequisite, just as the ZLG driver remains a CAN-adapter
|
|
prerequisite; neither is project source data.
|
|
|
|
Build without flashing:
|
|
|
|
```powershell
|
|
powershell -ExecutionPolicy Bypass -File .\tools\build_seat_firmware.ps1
|
|
```
|
|
|
|
Set `COGNITIVE_AGENT_IAR_BUILD` or pass `-IarBuild` when `iarbuild.exe` is not
|
|
at a standard location. The script stages the project beside repository-local
|
|
vendor junctions, copies the resulting HEX/OUT back, removes build products,
|
|
and never opens a debug probe.
|
|
|
|
The latest firmware uses periodic CAN `0x304`/`0x305` for motor and thermal
|
|
current diagnostics. The backend therefore verifies it passively by observing
|
|
`0x301` through `0x305`, `0x4FA`, all four motor IDs and MaxHall
|
|
`480/374/917/647`; it sends no identity request and no actuator frame during
|
|
verification.
|
|
|
|
When real hardware execution is enabled, automatic programming defaults to
|
|
enabled and uses `IAR/Seat_Controller_program.mac` to force outputs safe before
|
|
download. A missing protocol signature triggers programming, a boot wait and
|
|
passive re-verification before the original request continues. Set
|
|
`COGNITIVE_AGENT_SEAT_AUTO_FLASH_ENABLED=false` to opt out explicitly; dry-run
|
|
execution never programs hardware.
