I am transcribing the very first request. “I would like to modify mcan_loopback_interrupt to check the loopback of the classic CAN extended format.” "Q1.I would like the sample code, can I download it?” I studied classic CAN in the online documentation. mcan_loopback_interrupt.c This sample code is CANFD. mcan_loopback_polling.c This sample code is Classic Can, CANID is 29bit. 1. I modify mcan_loopback_interrupt.c to ClassicCan. 2. I confirm loopback with CANID 11bit. 3. I modify mcan_loopback_interrupt.c to CANID 29bit. 3. I modify mcan_loopback_interrupt.c to CANID 29bit. mcan_loopback_polling.c confirmed. 4. I confirm loopback with CANID 29bit. 5. I confirm CANID 11bit communication with 2 LP boards. 6. I confirm CANID 29bit communication with 2 LP boards. Result:. 2: Sending/receiving succeeds 4: Reception fails. I do not know why CANID 29bit is failing. I have corrected (*1)-(*5).
