Getting this issue with a PI 3:

Any ideas? Checked that start_x=1 and gpu_mem=128

Thanks

It can fail sometimes and also the module has been renamed at some point if I'm not mistaken

Here are the lines I've used for my project some time ago:

modprobe v4l2_common || true
modprobe bcm2835-v4l2 || true

I think actually only the 1st one is needed.

[SteveEdson]

Thanks for the reply. modprobe v4l2_common || true doesn't error, but the camera still doesn't work:

Oh wait, I had the camera in the wrong port! Thanks for the help :D

[emirotin]

:)

Both of these lines don't error because of the || true part. So what did the trick — changing the port or changing the port and the module name?

[SteveEdson]

Both, changing the module name fixed the software issue, the second line still doesn't work but obviously doesn't fail.

Then I had the second issue which made me realize my cable was in the wrong port. I'd recommend updating the docs/code for the v4l2_common module.

Thanks again.

— You are receiving this because you modified the open/close state.
