Has anyone been able to get the CAN bus working in Jetpack 4.1.1. I followed the instructions from this post:

https://devtalk.nvidia.com/default/topic/1042493/jetson-agx-xavier/enable-can-on-xavier/post/5295942/#5295942

I double checked the pinmux registers were set to the appropriate values but I still cannot get the CAN Bus to work.

If I run the controllers in SW loopback they work so the driver seems to be working however I am getting nothing in or out of CAND_IN or CAND_OUT. I checked both signals before our transceiver and see no activity from the module.

Any ideas for this?

Hi,
Can you please tell me which transceiver did you use and how did you make the connections? After knowing this, I can help you further.

Regards,

It was an issue with our transceiver. We have verified CAN now
