Can you send the output from
ip -details link show can0 (or whatever canX got stuck)
ip -stat link show can0 (or whatever canX got stuck)
just to see why the CAN interface gets offline.
Do you have a proper CAN setup (with CAN transceivers, real wires, 2x 120 ohms
termination, etc) ?
Sending CAN frames only works when there's a second/different node with the
same bitrate acknowledging the sent frame. Sending without cabling/termination
always leads to CAN controllers that feel sad :-)
Regards,
Oliver
