Ensure the CAN FD configuration settings match between the sender and receiver, including bitrate, timing, and protocol. Double-check hardware connections and consider debugging with diagnostic tools to pinpoint the issue.

Thank you for your reply, but now it can be normally sent to PC. pc receives CAN frames from the development board, but the development board cannot receive messages from PC

Thank you for your reply, but I still have the same problem when I use demo, and the development board still can't observe the CAN data frame from PC through PE. I don't know if there is a problem with my use method or something else, please help me test whether there is any problem with my program, thank you
