Problems you were having?
I have two identical Jetson Nano’s named A and B. On system A everything works fine, I am able to get perfect images from the quad imager using
python3 arducam_displayer.py -f GREY --width 5120 --height 800 -d 0. If I switch the SSD and all camera hardware to system B and run the same command the image flickers and there is some tearing from one camera view to the next.
The dmesg log from your hardware?
