Now I develop in S32R272 and I need to receive some CAN messages with DLC64 and a diagnostic message with DLC8, this diagnostic message is used for UDS function.
1.I config the payload size to 64 with CAN FD,then set the diagnostic request/response CAN message with DLC8;
2.I use CANoe transmit a diagnostic request message with DLC8 and waiting the ecu to receive this diagnostic request;
3.I find that when receive the DLC8 message, software stop run. I don't know why it happened.
If payload size was configured to 64, all received message's DLC should equal to 64?
Can I set the mixed dlc messages?
Ps: If the ECU has ever received/transmitted a 64byte can message, then receive a 8 byte message, it works normal.
If the ECU has never received/transmitted a 64byte can message, it stop working when received a 8 byte message first time.
