We encountered a problem. The communication rate between S32G and SJA1110 was changed to 1G on the RDB2 development board. After a period of normal operation, it was inexplicably unreasonable. I couldn't find the reason. Then I remembered the EVB development board. For the problem, I unplug the 12V power connector of the RDB2 development board and leave it for a while, then plug it in and power it up and the communication is normal.
