1.Please make sure external 12V power supply was used for S32K148EVB,elsewise the CAN PTY will not work.
2. these two demo enabled the CAN FD features, so please make sure the PC software configuration is right.
3. I made a sample demo for your reference, you can try it, this demo should periodically send frames with ID 0x01(500K)
