I am currently trying to get the Pi Camera Module 3 working on a Pi 4 B under NixOS, but I'm having some issues with the video core drivers (which I assume are needed to use the camera).
I'm seeing this output in dmesg (with verbose logging enabled for vchiq):
The interesting part is that no OPENACK is received from the video core after sending OPEN, and instead a CLOSE is received. Compare this to the dmesg output from Raspbian:
I am using u-boot and extlinux with the following config.txt:
And this extlinux entry:
I took the loaded device tree from Raspbian and copied it to my system (using dtc -I fs /sys/firmware/devicetree/base), and at runtime the only differences are below.
Anyone know what I might be doing wrong here?
I'm seeing this output in dmesg (with verbose logging enabled for vchiq):
