Can't access REPL on F767 Nucleo board.
Have flashed current pre-built firmware with DFU uploader through host USB port without errors.
Board appears as a USB 2MB flash drive.
Have tried accessing REPL through St-Link virtual com port that should be connected by default to Uart -3 PD8 and PD9.
Virtual ST-Link com port is accessible to PC terminal , but at 115200 baud I can't get any response from Nucleo board.
Any advice from Nucleo 767 board users would be welcome.
Regards
John
