Hi guys thankyou for the help, @Tesla DeLorean you was right! I assumed the deafult configuration for the nucleo board would be set to match the on board crystal which was 8MHz (the default value was 32MHz). changing the input frequency for HSE as pe...

Oh I assumed teh 8Mhz crytsal on the nucleo was the HSE source. The board I was using is teh STM32F072RB NUCLEO-64

Is this what you mean?
