LAUNCHXL-F280039C: CAN message cannot be sent, program is stuck in the acquisition flag dead loop

Part Number: LAUNCHXL-F280039C

Hi team,

Our customer has met some issues about  280039C/MCAN example.

Using the LAUNCHXL_280039C development board, the 280039C/MCAN example (mcan_ex7_classic_transmit) is builded, the CAN message cannot be sent, the program is stuck in the acquisition flag dead loop, the routine code has not been modified, CCS version 12.3.0. So how do you send data after configuring MCAN as a normal CAN?

The program is stuck waiting for the sending to completeThe sending request has always been 1, does this have anything to do with simulation?

They also want to know,

Many library functions use "while" to judge, is it possible that the watchdog is reset due to not getting the flag, or do you need to add a timeout judgment yourself?

Thanks and look for your reply!
