how to recover Jetson TX2 from CAN bus off?

Hi,

I am using CAN on Jetson Tx2 board, I could able to work with it fine. I could able to send/receive messages.I tested CAN is working fine with my tests.

But one of my test is to create bus off scenario, by making CAN-H and CAN-L short when communication is in progress. I could able to do that, it entered into bus off when i short CAN-H and CAN-L. can state is showing BUS-OFF and berr-counter is showing some values.

Now i am trying to recover from the bus off with option, restart-ms.

Followed seq :

sudo ip link set down can0
sudo ip link set can0 type can restart-ms 100
sudo ip link set up can0

Then my Jetson TX2 board starts Freezing up and then restarts automatically.

I don’t think this is expected behavior.

Can you please help me to fix this issue.

Thanks
