Jetson orin nano error canbus

[asilva2]

I am trying to read canbus over python, I followed the guide on the plataform, but any commando works on my terminal, is there any other option?

Hi asilva2,

Are you using the devkit or custom board for Orin Nano?
What’s your Jetpack version in use?

Have you referred to Controller Area Network (CAN) — NVIDIA Jetson Linux Developer Guide 1 documentation to setup CAN interface and verify CAN works as exepected?

[asilva2]

Im using developer Kit. Jetpack 6, I also did the firmware update, I have tried that Guide but on first command to check if status is Okay, the directory is not found.

I also went to “/proc/device-tree/”

But the “mttcan” does not show up

Should I need to install something before?

You have to run sudo modprobe mttcan to load driver.

Please let me know what commands you run and the results.
