Dear everybody,

in my code, i am not able to set my Port PD2 as output.

As can be seen, I stopped debug at line 294.

In lines 287 and 289 GPIOD->MODER and memory adress 0x4800 0C00 should be set to some value unequal zero,

but it keeps on zero.

Tried with different hardware, and tried with IAR and Keil.

I am stuck !

Any hints ?

Thx a lot, Jens

>>Any hints ?

Try enabling the clocks for GPIOD
