Blink User LED on Nucleo-F439ZI

[ap44]

I want to let the user LEDs blinken, however it is not working. When I run the code the LD4(COM) is blinking red and green. after the run the LD4(COM) is red the whole time and the user LEDs do not blink. Should the LD4(COM) be lighting green?

Could you maybe tell me where I can find the pin-configuration for my Board STM32- nucleo-f439ZI. I went through the whole user-manual but could not find it
