Hi,
I have succeeded to compile “Hello Wolrd” and also board programming doesn’t give any failures, but after then only LD1 blinks fast red and green. LD2 won’t go on.
I haven’t done any measurements yet but I guess board isn’t running program correctly or it’s stucked some way.
I have NUCLEO-F072RB board containing STM32F072RBT6 and I have expeted that PA5 is the correct port for LD2?
Do I need to do something for Hello World code to get a timer working?
