title: STM32 HAL_Delay Hangs on HAL_GetTick()
body: <p>I saw this problem happened before too. Their solution was adding </p>
  
  <pre><code>void SysTick_Handler(void) {
      HAL_IncTick();
  }
  </code></pre>
  
  <p>to stm32f4xx_it.c file.</p>
  
  <p>I checked priority of the "system tick timer", it is 0. So it has highest priority as well. </p>
  
  <p>Even blinky code is having same problem. Which it didnt have before.</p>
  
  <p>It was automatically added at me already. Is there any other place i should look for this problem?</p>
  
  <p>(It was working fine previously, I did not make any changes on the systick or clock.)
  Thank you</p>
