Any information on the driver used for camera access?
On Mobian, only /dev/video1 claims video capture capability via the sun6i driver and no controls are reported.
Code:
mobian@mobian:~$ v4l2-ctl --list-devices
cedrus (platform:cedrus):
/dev/video0
/dev/media0
sun6i-csi (platform:csi):
/dev/video1
mobian@mobian:~$ v4l2-ctl -d /dev/video0 -D

RE: Camera test on Phosh - edge - 05-25-2020
Poked around a bit more and there is a dmesg error for the ov5640 device for Mobian.
On pmOS, the camera "works" as a video device without autofocus. A video player is used for the viewfinder and can be used to "take photos".
RE: Camera test on Phosh - a-wai - 05-26-2020
Yes, last I checked the driver is loaded, but it can't init the camera, not sure what the problem is yet
