Dude are a 5 year old or what? I don't need to make anyone look like a fool. If you want to help at least understand the question ... I'm just trying to get my issue fixed, not to prove anyone wrong.
I said there's something wrong with the USB serial port not the board itself
OM222O:
I unplugged the board but as soon as connected it back, the TX led started flashing and after a few seconds windows gave me an error that the USB device is not recognized (I plugged the motor back in and the board is ok,because it started ti drive it again).
anyways, I plugged it back and somehow the code didn't start automatically again, so I managed to flash the memory with an empty code and it's fixed now. I don't know what was wrong with it to begin with, but caps should have drained and done smething ... idk
