## 构建
CoreP4 使用 ESP32-C6 作为 Wi-Fi 协处理器，通过 ESP-Hosted SDIO 连接。板级配置已包含实际使用的 SDIO 引脚和复位引脚。
早期 ESP32-P4 芯片使用 ESP-IDF 5.5：
```bash
python3 scripts/build.py m5stack/corep4 --name m5stack-corep4 --zip
```
ESP32-P4 v3.x（P4X）使用 ESP-IDF 6.0 或更高版本：
```bash
python3 scripts/build.py m5stack/corep4 --name m5stack-corep4x --zip
```
构建脚本会生成合并固件和 release ZIP。烧录前请确认设备使用的 ESP32-P4 芯片版本与构建变体一致。
