same result, nothing happens on the terminal window. i tried 2 different stm32, i even tried with changed rx/tx crossing.
is it possible that my stm32 is not correct programmed? i used the documentaion from this site (one time with the st-link utility, and one time while recompiling the hex file to be sure ist with 115200 baud)
do i have to make special settings in the st-link utility?
here the log file form st-link:
