Some people might be affected by some driver bug where the camera:
- does works right after boot of the PinePhone Pro.
- But after suspend, the camera stops working.
e.g.: that's the case when using application
Shutter on
SailfishOS.
The following trick forces reinitialising the hardware (as if the kernel is populating from device tree during a boot):
Code:
echo ff920000.isp1 | sudo tee /sys/bus/platform/drivers/rkisp1/{unbind,bind}

Thank you.
I added script
/lib/systemd/system-sleep/90-restore-cam.sleep
on mobian. It seems to work well.
Code:
#!/bin/sh
PATH=/sbin:/usr/sbin:/bin:/usr/bin
case "$1" in
pre)
#code execution BEFORE sleeping/hibernating/suspending
;;
post)
#code execution AFTER resuming
echo ff920000.isp1 > /sys/bus/platform/drivers/rkisp1/unbind
echo ff920000.isp1 > /sys/bus/platform/drivers/rkisp1/bind
;;
esac
exit 0

That's a very cool solution! ?
(Sadly in the case of SailfishOS that doesn't work. Apparently the solution for suspend used there doesn't run those scripts
).
: Is there a way that you could do this in a "cannocial" way in the driver code ?
