Compute Module • Re: CM3 and Waveshare PoE board cameras

Hi 6by9!

Sorry, my previous post was from pure frustration.

I can detect the cameras on the I2c buses when using pinctrl to enable them. But my question is, if Bookworm doesn't use the dt-blob.bin and only libcamera is supported... how am I supposed to let the CM3+ know what cameras it has?

How does the pi find the cameras? there is no camera menu in the raspi-config anymore.
is it all handled in the /boot/firmware/config.txt with dtoverlay=imx219,cam0/1?

I've tried swapping the i2c buses, i've tried setting the regulator pins in the config.txt.
I cannot see any activity on my osciloscope when I run libcamera-hello --list-cameras.
Nothing on the i2c buses, nor the regulator or led pins.

I know the cameras work, they have no issues on a pi 3b+.

If I do have to tell the pi somehow the pinout of the cameras and CSI lanes how should I do this in Bookworm?
Are there steps to enable the cameras?
I'm really lost at this point. I'm using the official 2.1 camera and if I can't even get these to work I'm not going to try any other of the more specialized cameras.

Should I switch back to a previous Raspbian OS?
How does libcamera know there even is a camera?
Is this something that is still being worked on for the Compute Modules or should it be able to run?
If I was using the Official Raspberry CMIO board how would that work with Bookworm?

Sorry for so many questions, I really prefer to understand things and work my way up, but as said before, I'm lost at this point.

Thanks!!
