Degugging locks up at "Initializing PLDs..." Posted by LaurentL on 2016-08-26 15:55 Which STLink are you using so ? a v2 ? or v2-1 ? Nucleo are 2-1, some newer discovery too. I suppose you did a custom board selection but did you choose the right stlink and device? Choose SWD as transport. Which device is it ? Rgds, Laurent
