Hello,
I do not normally post here, because I try to solve as much of the problems by googling and investigating.
But now my skills end. I do not know what to do next. I have followed every tutorial and video about this board.
So to the problem:
I have this board (except the F401RCT6 version):
It does show in device manager as USB serial drive when its not in boot mode. Whenever I switch it to boot mode (turn on sw3) the blue light shuts down and it disappears from device manager.
What should I do next? Could it be programmed without USB trough serial?
