Hello, Jetson Xavier developer kit. I installed can driver before, which enables can0 and Can1 interfaces to send standard frames. However, it’s uncertain whether the CANopen message can be sent, whether it can be used, and how to use it

Jetson integrates Bosch MTTCAN controller which does not support CANopen protocol.
You can use standard, extended and FD frames to transfer.

Hello, do you have any demo examples

Please go through the doc:

Let me know if you need further help.
