Jetson Xavier CAN BUS Fault

Hello,

I was using the can bus for a while on Xavier with no issues however, there is an error that occurs randomly makes the bus go to an off state and can’t send any message anymore. I have to reboot even when I try to restart the bus it says >> RTNETLINK answers: Device or resource busy. Is there any conflict between CAN and other communication protocol ?

Sometimes, the same configuration works for days and then randomly with the same sw and hw setup, the can bus stops after sending one message.

I am using PyCAN library.

hi mahmoud,
Can you give more details of the issue like commands being used and logs.
When you try to restart, CAN interface is already up on the network therefore it says busy. You need to make it down then restart.

Thanks,
Shubhi
