LAUNCHXL-F280039C: CAN Bus Communication Issue

Part Number: LAUNCHXL-F280039C
Other Parts Discussed in Thread: C2000WARE

I'm using LAUNCHXL-F280039C board with CCS V20.4.0.13, and also installed C2000Ware_6_00_01_00.

I connected two these EVB boards on J14 (CAN A), all 3 pins, and I'm using an example project: can_ex5_transmit_receive, from C2000Ware.

I made one project as TRANSMIT and loaded the build on one EVB board to transmit CAN message. In Debug, CAN_sendMessage() is called peroidically. (I modified the code and let it transmit the message every 1s).

I also made another project as RECEIVE (commoned out 'TRANSMIT') and loaded the build on the other EVB board to receive CAN message. I set a breakpoint inside Interrupt call: canaISR(), but the breakpoint never got trigged. 

Did I miss anything in this exercise?

Thanks

David
