Thank you for providing these details. One thing I notice right away is that the voltage thresholds on CAN_H/CAN_L: f28p65x to zc702: 0.8V to 2.4V zc702 to p28P65x: 2.5V to 3.8V ***This will cause errors This 2.5V signal will not be recognize as a recessive bit on the CAN bus. Please refer to the document below on debugging the CAN physical layer for next steps on debugging.
