+# ESP-P4-Function-EV-Board
+
+Board support for ESP-P4-Function-EV-Board. Wi‑Fi uses ESP‑Hosted via the on‑board ESP32‑C6. LCD is supported via the official MIPI‑DSI LCD adapter.
+
+## Features
+- Wi‑Fi: `esp_wifi_remote` + `esp_hosted` (SDIO) with ESP32‑C6 co‑processor
+- Display: 7" MIPI‑DSI LCD (1024×600) via adapter; can also run headless
+- Audio: Can run with dummy codec; board includes ES8311 + PA if needed
+
+## 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.
