I’m having trouble getting image frames out of my camera sensor. I have a camera connected via an FPDLink SerDes pair to a MIPI CSI-2 expansion board. When I run
v4l2-ctl -d /dev/video0 --set-fmt-video=width=2880,height=1860,pixelformat=RG12 --stream-count=1 --stream-mmap --stream-to=csi.raw --verbose
I get this message repeatedly in dmesg:
