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.
