I use S12G128 for the BOOTloader update program, which is done in reference to the 4528 document.Currently, when you want to run the APP, you receive the update program command from the serial port, and it executes the bootloader code itself.The current situation is that during the implementation of the APP, we hope to update the program, open the watchdog immediately, and reset.The program doesn't know where to go.Any similar information.thank you
