Posted on October 14, 2017 at 12:59Hi, I'm getting started with the Nucleo STM32F411RE, and the LED don't light !
Here is my main.c :

RCC_DeInit();
GPIO_InitTypeDef GPIO_InitStructure_Led;
RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOA, ENABLE);
GPIO_InitStructure_Led.GPIO_Pin = GPIO_Pin_5;
GPIO_InitStructure_Led.GPIO_Mode = GPIO_Mode_OUT;
GPIO_InitStructure_Led.GPIO_OType = GPIO_OType_PP;
GPIO_InitStructure_Led.GPIO_PuPd = GPIO_PuPd_NOPULL;
GPIO_InitStructure_Led.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_Init(GPIOA, &GPIO_InitStructure_Led);
}
int main(void)
{
Init();
//GPIO_WriteBit(GPIOA, GPIO_Pin_5, Bit_SET);
GPIO_SetBits(GPIOA, GPIO_Pin_5);
while(1)
{
}
}

The build is successful, and I can flash the .bin file via ST-Link Utility. But it doesn't work. The LED stays off.
There is no clue which could lead me to a solution, because all the compiling and flashing processing works fine.
Is there something missing in the code ? Something I forgot to configure ?
Thanks for your help !
