It is a question on how to assign an ISR to a specific CAN function (one for rx and one for tx). It is not specifically a FreeRTOS question, but is a question where I hope to use the version 9.0 demo for RM48 as a starting point.
I already have changes that allow a J1939 message (Address Claim) to be transmitted, but I am not seeing any reply or CAN/J1939 frames. I suspect my ISR setup, since those appear to not be assigned.
I am confident in my communication wiring and resistor setup, since intended traffic is visible on USB CAN tools and those tools capture the 1939 Address Claim message from the RM46x HDK board.
Any advice would be appreciated. Any guidance on whether I should be looking at specific interrupts or specific channels might also be helpful.
It might be a FreeRTOS question if considered along these lines: For any FreeRTOS demo created for the TI Hercules RM4 series, has anyone added CANBUS support? If so, how did you do it?
