## Configure
|
|
|
|
|
|
In `menuconfig`: Xiaozhi Assistant -> Board Type -> ESP-P4-Function-EV-Board
|
|
|
|
|
|
|
|
|
|
|
|
Ensure these are set (auto-set when building via config.json):
|
|
|
|
|
|
- `CONFIG_SLAVE_IDF_TARGET_ESP32C6=y`
|
|
|
|
|
|
- `CONFIG_ESP_HOSTED_P4_DEV_BOARD_FUNC_BOARD=y`
|
|
|
|
|
|
- `CONFIG_ESP_HOSTED_SDIO_HOST_INTERFACE=y`
|
|
|
|
|
|
- `CONFIG_ESP_HOSTED_SDIO_4_BIT_BUS=y`
|
|
|
|
|
|
|
|
|
|
|
|
## LCD Connection (from Espressif user guide)
|
|
|
|
|
|
- Connect the LCD adapter board J3 to the board’s MIPI DSI connector (reverse ribbon).
|
|
|
|
|
|
- Wire `RST_LCD` (adapter J6) to `GPIO27` (board J1).
|
|
|
|
|
|
- Wire `PWM` (adapter J6) to `GPIO26` (board J1).
|
|
|
|
|
|
- Optionally power the LCD adapter via its USB or provide `5V` and `GND` from the board.
|
|
|
|
|
|
|
|
|
|
|
|
These pins are pre-configured in `config.h` as `PIN_NUM_LCD_RST=GPIO27` and `DISPLAY_BACKLIGHT_PIN=GPIO26`. Resolution is set to 1024×600.
|
|

|
|
## Build (example)
|
|
|
|
|
|
```powershell
|
|
|
|
|
|
idf.py set-target esp32p4
|
|
|
|
|
|
idf.py menuconfig
|
|
|
|
|
|
idf.py build
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
Tip: In menuconfig, choose Xiaozhi Assistant -> Board Type -> ESP-P4-Function-EV-Board.
|
|
|
|
|
|
If building a release via scripts, the `config.json` in this folder appends the required Hosted options.
