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).

> 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）

Attention

**Burn system image(`maixcam_*.img.xz`(for device MaixCAM) or `maixcam-pro_*.img.xz`(for device MaixCAM-Pro) file below) to use this version because it have camera driver update in system, and don't forget to install runtime in first bootup**
**烧录系统镜像(下面的`maixcam_*.img.xz`(设备 MaixCAM 用)或`maixcam-pro_*.img.xz`(设备 MaixCAM-Pro 用)文件），以及第一次开机后记得联网安装运行库，才能正常使用此版本**
