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, old version system DO NOT upgrade runtime
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安装运行库，才能正常使用此版本

Attention

For this version, if you want to use HID function, you must burn system, or you can upgrade maixpy and then upgrade runtime, but we remain recommend you directly re-burn system.

Burn system image(*.img.xz file below) to use this version because it have camera driver update in system, and don't forget to install runtime in first bootup, old version system DO NOT upgrade runtime
