Which Khadas SBC do you use?
VIM3
Which system do you use? Android, Ubuntu, OOWOW or others?
Tried to access the camera on android 9 clear AOSP build with default app and on vim3-ubuntu-20.04-gnome-linux-4.9-fenix-1.4-221229-emmc.img with guvcview.
Please describe your issue below:
I’m not sure, but I think I burned the camera. I read about this super ability of the camera only after tried to connect it, then I found out that it didn’t work, disconnected it from device and read docs. Still, I hope that something is wrong with the firmware. Connecting the camera, it clicks once or twice. There are no logs from android, but the logs from guvcview on ubuntu are full of errors related to V4L2_CORE.
Post a console log of your issue below:

the last one repeats until I force quit from the app.
I already fixed few first errors by reinstalling libasound.
@numbqq, did I burned my camera?
