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
