Hi all! I am new to jetson and I am trying to connect can bus (mcp2515 8000000hz) to jetson nano dev kit. But I can’t get the jetson-io.py script to see my dtbo file. There was already a similar topic on the forum ( https://forums.developer.nvidia.com/t/jetson-io-py-cant-find-dtb-file-on-jetson-nano…

I solved my problem by making a UART to SPI adapter using an arduino nano board. I was afraid that this would not work, but I managed to send frames to CAN every 100ms. I think it can be even faster. If someone needs this life hack, I can attach instructions.

The trouble with work jetson-io.py to connect the can bus to the jetson nano devkit

If you are using the custom board for Jetson Nano, Jetson-IO might not work for your board.
You could refer to the following thread step-by-step for SPI loopback test.
