Camera stops working after resume from suspend

[DrYak]

Okay, I just ran into this issue, but only on the back (main) camera. The front camera facing the user does wake from suspend.

Had the exact same problem on SailfishOS (I haven't checked recently if it stil happens with latest updates).

Main camera is talking over MIPI CSI to the image processing core (ISP) of the RockChip RK3399.

So last time I used to reset RKISP1 and it brought back the camera:

Code:

echo ff920000.isp1 | tee /sys/bus/platform/drivers/rkisp1/{unbind,bind}

(As root. So either log as root or put "sudo" in front of "tee")

Maybe this helps? (I am not sure. Worked for me, but not for users of different distro. Maybe try restarting Pipewire, after having resert RKISP1 ?)
