@jack_admin @大法师 现在支持HQ Camera了吗

@大法师 先支持HQ Camera吧，视觉应用是大头

@ccjjww1222 V11版本是板载天线。V10是外置天线，你的是哪个版本

@大法师 建议尽快支持一下树莓派的HQ Camera，传感器型号是IMX477R，现在这款摄像头很火，可以匹配各种不同的镜头。IMX708支持自动对焦，是新出的产品。

可以通过了，就因为文件路径存在空格

@大法师 是权限问题，修改/media/coolpi文件夹的用户为coolpi就可以了

@jack_admin 已经成功

@george 试了不能用

原因找到了，是configuration 那里要设置选择HFP

@jack_admin 那就没有问题了，只要优先从tf卡启动就行，我已经通过tf卡启动ubuntu22.04，然后通过dd命令将img写入到emmc中，并且启动成功。这样就再也不用把emmc从板子上取下来了，yeah！谢谢

@xingzhan2012 可以用cool pi ubuntu系统，直接dd 刷系统到其他存储介质，比如emmc
