CAN Trace
the biggest frequency of all 300RI packets is 100hz, so i do not think it is from 300RI, i doubt it is caused by other nodes or other abnormal CAN tools SW setting.
any other node in CAN-net work? is it possible other nodes send the '000'-ID out?
power off 300RI after 2-3s, and then check '000'-ID is still received or not?
