I have a problem with the connection. Yesterday my board stopped working (there is a file FAIL.txt: "The interface firmware FAILED to reset/halt the target MC" at board disk). I've done some research on how to fix it, but neither pressing reset nor connecting boot0 to Vdd worked. After some time I managed to connect to the board - I removed JP5 jumper and connected MCU to STLINK (on the same board) through wires (How to reconnect nucleo to st-link part?) and after many tries to unplug and plug the USB cable sometimes it works - I can programm my board as before. Any ideas on what could it be and how to fix it? EDIT: Ok, it's not stlink. So when Im taking off PWR jumper and inserting it again couple (random number) times it finally connects and then I can work normally until I reconnect cable. Any idea?
