I am using MBDToolbox to work on DEVKIT-S12ZVC.
but when Progress MCU,it did not work.
I have flash the S12ZVC.rbf into the DEVKIT-S12ZVC.
Thank you for your reply.
This is my board.
I have connected UART use COM4
Can you add a picture of the board and see how you have connected the UART with the board ? There are different UART connector between programming the application and running it.
