STM32L431CBT6 blocks in HAL_Delay()

Greetings! I am using STM32 for a very first time. I made my custom PCB with 10MHz oscillator. In the Clock Configuration window I have sellected the PLL and the HCLK is set to 80MHz (max for the uC). The outputs are all 80MHz. So I made a simple blink test program:

 

  /* USER CODE BEGIN WHILE */
  while (1)
  {
	  HAL_GPIO_TogglePin(LED_1_GPIO_Port, LED_1_Pin);
	  HAL_Delay(1000);
    /* USER CODE END WHILE */

    /* USER CODE BEGIN 3 */
  }

 

The problem is my code blocks in HAL_Delay(). Here to be precise:

 

while ((HAL_GetTick() - tickstart) < wait)
  {
  }

 

I checked with oscilloscope and the quarz is working! I also tried different interrupt priorities for Sys Tick Timer.

Any other suggestions?

I have no experience with these uC.

Thanks!

Though it may not matter with what code you have that I see, you've have the Systick priority set to 14. Usually by default, it should be 0 like all the other interrupts.

 

Are you sure you've selected the correct pin for the LED? 

Don't worry, I won't byte.

Hello,

Is that possible to share the part of the crystal connected to the MCU + the part of the LED connection with the MCU.

When you set a break point at HAL_GPIO_TogglePin(LED_1_GPIO_Port, LED_1_Pin) are you able to reach it?
