RTOS and reading file ?

Everyone,

I tried to read file and write file in one task on RTOS, but

when I read file it's stopped in the middle ?

What setting do I need to change in the task ? Is it related with timer2 per task ?

Code :

void StartDefaultTask(void const * argument)
{
 /* init code for FATFS */
 MX_FATFS_Init();
 /* init code for USB_DEVICE */
 MX_USB_DEVICE_Init();
 /* USER CODE BEGIN StartDefaultTask */
 /* Infinite loop */
test_fatfs();
reading_file_test(); <== stop in the middle here
 for(;;)
 {
 osDelay(1);
 }
 /* USER CODE END StartDefaultTask */
}
�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?

I have tested without RTOS, it can read properly,

I have used timer2 as SYSTICK, and how to configure that for RTOS ?

What do you reckon I missed here ?

Thanks

void SysTick_Handler(void)
{
 /* USER CODE BEGIN SysTick_IRQn 0 */
 /* USER CODE END SysTick_IRQn 0 */
 osSystickHandler();
 /* USER CODE BEGIN SysTick_IRQn 1 */
 /* USER CODE END SysTick_IRQn 1 */
}�?�?�?�?�?�?�?�?�?�?

Is it related with that line ? ( Line 6 )

Do you have only one thread? Actually threads will execute on time basis so it will switch to another thread, and when the control comes back to this one, it will only execute the infinite loop.
