I just want to blink an LED. I’m using a Nucleo 32 dev board. (F042K6) It compiles without any errors, but when I program the code, the LED does not change state. The code is below. I program the test4.bin using STM32 ST-Link Utility Are there any other settings for the GPIO I need to set? Any help is greatly appreciated.

1. include “stm32f0xx.h”
2. include “stm32f0xx_nucleo_32.h”

int main(void)
{
RCC->AHBENR |= RCC_AHBENR_GPIOBEN;
GPIOB->MODER |= GPIO_MODER_MODER3_0;
GPIOB->PUPDR &= ~GPIO_PUPDR_PUPDR3;

for(;;)
{
HAL_GPIO_TogglePin(GPIOB, GPIO_PIN_3);
HAL_Delay(500);
}
}
