@Ultrawipf PTAL Do you think it's better to merge or separate into another branch?

Sorry for my late reply! I am in China and under the COVID-19 lockdown. It is more convenient for you to make a PCB yourself. Please see the [v1.1](https://github.com/TDA-2030/OpenFFBoard/tree/board/esp32s2_openffb/v1.1/openffboard-esp32s2) version...

Thank you for your feedback. The fact is exactly what you said. We will fix it as soon as possible

You are right. there is no initialization for pointer of write_command. Only the 8080 interface initialized this pointer: https://github.com/espressif/esp-iot-solution/blob/ff6da114532ef11768fa2516149cf921c538722a/components/display/screen/interface_driver/scr_interface_driver.c#L299

我用的是 cmake 编译，`firmware/main/CMakeLists.txt` 文件的 spiffs_create_partition_image 命令会写入 spiffs 的镜像。具体用法可参考 IDF 编程指南的 [SPIFFS 文件系统](https://docs.espressif.com/projects/esp-idf/zh_CN/latest/esp32/api-reference/storage/spiffs.html#id3)

是的，自动烧录到 partition 指定的分区
