Hi,

I tested your code on S32K144EVB-Q100 and with PCAN tool connected I see CAN FD message periodically received. Using a debugger no error is detected on FlexCAN module.

In you case error frame is sent, I guess. You can check module MCR/ECR/ESR1 registers to see a state and error detected. If using S32K144EVB-Q100 as well on your side, be sure board is powered by 12V and SBC CAN transceiver is active.

Hello PetrS
I follow you code, and S32K144EVB-Q100 board is powered by 12V, and PCAN setting is same. but the CAN is seem not woking. The CANH-GND/CANL-GND is 1.3V, is it means the SBC CAN is not active, can you help me?
