Based on the shield buddy board (TC275), I would like to realise the CAN communication. I am wondering if there is the canfd transceiver IC in this board to be able to realise this function.
I tried my codes for a long time but it didn't work.
In the attached file are my codes.

Please refer this TC274 MULTICAN_FD code,  the loopBackMode should be disable and set pins.
