Problem GPIOs WeAct Board STM32F411CEU6 and STM32F401CEU6

Hi,

I can't program the GPIOs

levels don't change and stay in reset mode, what's the problem?

I use the HAL STMF4

Maybe you help me please!!!

Thanks for the advance!

Not much info you're giving us. Here are some possibilities, in order of likelihood:

Code bug (show your code, or go from an example)
Misunderstanding (perhaps you are monitoring the wrong pin, or the pin isn't connected how you think.)
Hardware issue (solder bridge, broken trace, cold joint, etc.)

Consider going off of an example and adapt it for your board:
