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](https://wiki.sipeed.com/maixpy/doc/zh/basic/upgrade.html).


> 烧录系统镜像，下面 assets 中的文件：
> * `maixcam_*.img.xz`: 设备 MaixCAM 用
> * `maixcam-pro_*.img.xz`: 设备 MaixCAM-Pro 用
> 注意**不要烧录错镜像文件**，烧录错会导致屏幕烧屏（一般放置一段时间会缓慢恢复）
