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](https://docs.nvidia.com/jetson/archives/r34.1/DeveloperGuide/text/HR/ControllerAreaNetworkCan.html) with one exception - to set up the 40 pin headers using [this guide](https://docs.nvidia.com/jetson/archives/r34.1/DeveloperGuide/text/HR/ConfiguringTheJetsonExpansionHeaders.html#hr-configuringthejetsonexpansionheaders) 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: state UP mode DEFAULT group default qlen 10 link/can promiscuity 0 minmtu 0 maxmtu 0 can state ERROR-ACTIVE (berr-counter tx 0 rx 0) restart-ms 0 bitrate 500000 sample-point 0.870 tq 20 prop-seg 43 phase-seg1 43 phase-seg2 13 sjw 1 mttcan: tseg1 2…255 tseg2 0…127 sjw 1…127 brp 1…511 brp-inc 1 mttcan: dtseg1 1…31 dtseg2 0…15 dsjw 1…15 dbrp 1…15 dbrp-inc 1 clock 50000000 re-started bus-errors arbit-lost error-warn error-pass bus-off 0 0 0 0 0 0 numtxqueues 1 numrxqueues 1 gso\_max\_size 65536 gso\_max\_segs 65535 RX: bytes packets errors dropped overrun mcast 2 1 0 0 0 0 TX: bytes packets errors dropped carrier collsns 2 1 0 0 0 0 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! ---
