Problems with USB2CAN MODULE in Jetson-orin-nano/nx-dev-kit

I was hoping I could get some help with the USB2CAN-Module working for jetson orin nano on Ubuntu 22.04. I have connected it over USB and set up a small CAN network of one motor (a falcon 500). I can start it up with ip commands, but whenever I send any CAN message it goes down immediately saying:

[ 7990.696285] mttcan c310000.mttcan can0: Bit0 Error Detected

[ 7990.696337] mttcan c310000.mttcan can0: Bit0 Error Detected

[ 7990.696389] mttcan c310000.mttcan can0: Bit0 Error Detected

[ 7990.696454] mttcan c310000.mttcan can0: entered bus off state

[ 7990.696456] mttcan c310000.mttcan can0: Bit0 Error Detected

The wiring seems correct and we have added a 120 ohm resistance at the end, is there anything else to help debug?

Hi dittmargreav,

What’s the Jetpack version in use?

Are you using USB2CAN module or internal mttcan to control your CAN device(motor)?

You said that you are using USB-CAN module but the error is from internal mttcan driver.
Please share the block diagram of your connection for further check.
