I'm developing a CAN-FD bus for my project using the RENESAS RH850F1X-V3 MCU. When I transmit a CAN-FD frame, the receiver on the RH850 side captures it normally (Figure 1), but Wireshark indicates a bit stuffing error (Figure 2). I've verified the baud rates on both sides and discovered that if I set the FDF bit to 0 and use the classical CAN frame, the analyzer works correctly (Figure 3). However, the reception of CAN-FD frames seems weird on the Wireshark.
