Hello!
I am trying to get my Jetson AGX Orin dev kit communicating with an Agliex Tracer robot base through the CAN bus.
I am running Ubuntu 20 and Jetpack version 5.0.2-b231.
I followed the CAN bus setup according to this guide with one exception - to set up the 40 pin headers using this guide
I am using the recommended Waveshare SN65HVD230 CAN Board
I am able to successfully perform a loopback test with the output:
apricity@ubuntu:~$ cansend can0 123#abcd
can0 RX - - 123 [2] AB CD
can0 TX - - 123 [2] AB CD
Running ip -details -statistics link show can0, I receive the following:

Over the course of troubleshooting over 2 days, the NVIDIA pc was able to receive the CAN signals for about 10 seconds and then randomly stopped. Any ideas on how to debug further? Thank you!
