      Coolpi supports UMS to update emmc firmware, as follows:

      1. Update the latest versions of loader and uboot images. You can also synchronize uboot code and compile it yourself.
      git clone https://github.com/yanyitech/coolpi-loader
      cd coolpi-loader
      ./build-uboot.sh cp4b
      
      1. Connect a dual A port USB cable to the computer and the upper USB 3.0 interface. Plug in the power and press the power button three times, and the machine will enter UMS mode.

      2. Use Etcher software to update the software.

                  @Twsuts 这个固件是百度网盘或者onedrive下载的系统img格式固件。不是内核编译脚本生成的。
