Getting CSI camera to work on Raspberry Pi 5?

[crabdancing]

Has anyone gotten the CSI (ribbon cable connector) camera to work on Raspberry Pi 5 with this? I merged #330393 in my personal copy of nixpkgs stable, and it builds & deploys correctly -- but I can't seem to see the CSI camera no matter how many times I poke around with v4l2-ctl or /dev. What am I missing?

#42 achieves the same thing as the libcamera upgrade, but when a camera is detected running any of the libcamera apps results in a segfault. I haven't gotten any further with it

Hmm. Maybe a dep being behind upstream on 24.05 is causing it?

I'm also struggling with this: the current flake does not compile since rpicam-apps 1.5.2 seems to need libcamera 0.3.2 for IMX500 compatibility. But even if downgrading rpicam-apps to 1.5.1, when using nixos-24.05, I'm getting a segmentation fault.

I only get an abort with coredump, while complaining about missing backend_default_config.json in libpisp on nixos-unstable. Correcting does not fix it.

I also tried updating everything, but got nowhere; I will likely try that again soon, but if anyone has any pointers or ideas that would be lovely :D
