i am trying to interface stm32f411ceu6 with sdcard  using spi ,and i have successfully interfaced it but when i try to run this code using freertos by using another timer as timebase source it not works 

below code is in interrupt .c file . i wanted to use freertos just to make task but i dont know why my code not works when i enable freertos from stmcubemx

void SysTick_Handler(void)
{
  /* USER CODE BEGIN SysTick_IRQn 0 */
  if(Timer1 > 0)
    Timer1--;
  if(Timer2 > 0)
    Timer2--;
  /* USER CODE END SysTick_IRQn 0 */

  HAL_IncTick();

  /* USER CODE BEGIN SysTick_IRQn 1 */
  /* USER CODE END SysTick_IRQn 1 */

}

So what, exactly, does "not working" mean?

• What were you expecting it to do ?
• What is it actually doing ?
• What debugging have you done to find why it's "not working" ?

How To Debug.

You haven't shown your definitions of the two timer variables. They are being updated in an interrupt handler, so are they volatile ?
