Millipixels - 16MP Autofocus IMX519

Hello,

I have the 16MP Autofocus with the IMX519 driver installed and it works fine with the libcamera-XXX
demo apps.
I know Linux, but I’m new to the RespberryPi and ARM and libcamera stack.

Now I’m trying to get millipixels (Librem5 / millipixels · GitLab) to work. Therefor I have to create an ini file. I think the media-driver entry is wrong, but I have no idea what to enter there.

This is the output from millipixels:

$ ./millipixels

Could not find /dev/media* node matching 'bcm2835'

The other thing that is irritating me is that I don’t have /dev/media* devices. Is that normal?

This is how the ini file looks at the moment:

It looks like the driver settings are normal, I don’t know much about millipixels, maybe it’s a software support issue? Does it work if you use official camera like IMX477 or IMX219?

Thanks for the fast answer. Sadly I don’t have a official camera like IMX477 or IMX219, so I can’t test it. But perhaps you can tell me, if there should be /dev/media* devices or if it is normal, that I don’t have them.

Or do you know any touchscreen friendly app and works with your IMX519 camera?

If you turn off the touch function it will work.
But like you said the libcamera-xxx application works normally, which means there is no problem with the camera and driver.
