I would like to program my stm32 discovery board via st-link, to do this i am trying to power my board externally by using 5V pin. However, when i powered the board, ld1 com turns red, but it blinks. In this case, the program loaded in board runs, but i am not able to connect to it via st link; it gives an error that 'no target connected'. Do you have an idea about the problem here?
