Attention

Burning the system image, the following files in the assets folder:

• maixcam_*.img.xz: For the MaixCAM device.
• maixcam-pro_*.img.xz: For the MaixCAM-Pro device.
  Be careful not to burn the wrong image, as burning the wrong one may cause screen burn-in (it usually recovers slowly after being left for a period of time).

More info refer to documentation.

烧录系统镜像，下面 assets 中的文件：
