hopefully this works for @cowboysdude as well

I just typed in the sudo modprobe bcm2835-v4l2 and it returned nothing so I’m guessing that’s a good thing LOL

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.

Huge thank you to @strawberry-3-141 for helping to troubleshoot this issue and suggesting the solution! While I know all kinds of dev languages and tools, I am pretty new RPI and Linux.

Hi guys,
I have a problem. My MM do not turn on the display in the morning. I is possible that my pi camera is in a kind of sleepmode or standby? I have to restart with pm2 stop mm and start again an than it works fine.

I have encountered that MANY times… don’t exactly know why myself… It’s not just this module it happens with most of them… I believe once it sleeps long enough the PI doesn’t want to wake up LOL

Hi Guys,

had exactly the same problem with mit Raspi NOIR Cam V2.1.
the sudo modprobe bcm2835-v4l2 command solved my problem.

maybe you should add this Tipp in your Readme as many people out there have the same problem.

Hi Christoph
Unfortunately it didn’t work for me;o( Today my screen did not turn on. My Pi works and I can connect over ssh but I have to stop and start my MM and thank works again fine. I just think that my camera stop working if there is no motion a long time (during night).

I got some errors during the night:
