Are you using the devkit or custom board for AGX Orin?
What’s your current Jetpack version in use?

Have you refer to the following instruction for CAN usage or did any loopback test to verify?
Controller Area Network (CAN) — Jetson Linux Developer Guide documentation (


Which CAN bus works fine? Which CAN work with issue (CAN3!?)?

Hi Kevin,

Thanks for your reply.

Jetpack version is Jetson_Linux_R35.2.1_aarch64.

We will study flowing link first.


Yes, please make sure it works fine with internal loopback test first.

You could also use latest JP5.1.1(R35.3.1) to verify and we could synchronize the status.

Hi Kevin,

The native CAN works, and one of the SPI to CAN channels can send data, but cannot receive data.

I will update to JP5.1.1(R35.3.1).


Have you also verified SPI2 work with loopback test? (through shorting MISO and MOSI together)?

I’m look forward to your result.



Is this still an issue to support? Any result can be shared? Thanks

Hi kayccc,
