Jetson many CAN bus errors

Hello there!

Faced problems when working with CAN BUS. There is TX2 to which the CAN Tranciever is connected (120 ohm available). There is a receiving device (not TX2). At the moment when I turn on TX2, “Error frames” appear in large numbers on the receiving side, the same situation when rebooting and when turning off TX2. What could be the problem?

It is connected correctly, because using the cansend command, you can send a message to the receiving device. Maybe I configured something incorrectly, is there a need to write something to the system kernel?

Also on this topic. There is also NVIDIA XAVIER AGX. There is a similar problem. There are no errors when turning on, but when XAVIER is turned off, 1-2 “Error frames” appear stably on the receiving device. Has anyone faced such problems?

Thanks!

Hi silaj,
Which jetpack BSP version you are using?

Installed JetPack 4.2.3 version

Hi silaj,
There is a clock issue in J4.2
So, I would recommend to switch to latest versions. Issue is fixed in J4.3 so it is also fine.
Let me know if you face issue with J4.3 also.

Thanks,
Shubhi
