So this is what I’ve done and it solved it…
I took your sudo modprobe bcm2835-v4l2
and entered before I started the mirror and no more error so I started the mirror in dev and it was registering movement…Great!
So I closed the mirror and restarted… same error, driver not loaded…
so I did this in case of a power out,e tc…in a terminal window:
sudo crontab -e
Enter this on the last line:
@reboot sudo modprobe bcm2835-v4l2
Saved and exited.
Reboot
Restart mirror in dev mode
NO error and tracks movement
close mirror and restart in dev
NO error and tracks movement.
PROBLEM SOLVED!! Thank you guys for being patient!! It’s working.
