After further testing with all the mcp251x. files from here on the forum i had to follow Mcp2515 on jetson nano to even get the .dtbo to show up after running /opt/nvidia/jetson-io/jetson-io.py. I also removed the expansion shield and switched interrupt pin to different ones like 31, 22 etc as other users here have tried with no success…
Still stuck at:
dmesg | grep mcp
