STM8 and STVP: how to flash .HEX file

Hi everyone.

I have an .HEX file that I would like to program in a STM8AF62A8 MCU. I load the .HEX into STVP and it seems to be flashing the memory correctly because I can see some of the application's startup output through the serial port (it does it repeatedly due to the MCU being restarted multiple times during programming, I assume). The problem is that, as soon as the process is over, the MCU stops responding and I get no serial output when I reset the MCU manually. #hex #stvp #stm8

Hello,

When STVP has finished, the Swim (communication) is disabled and the mcu is held under reset.

If you unplug the programmer, the mcu should be running.

Rgds,
