Setting on RTOS ?

Everybody,

How can I use SDIO, USB with RTOS ?

I tried initialized RTOS but, SDIO is stopped initializing for some reasons,

Anyone knows ?

Without RTOS, they are working ok.

How to put those functions inside RTOS ?

I tried to understand :

http://www.st.com/content/ccc/resource/technical/document/user_manual/2d/60/ff/15/8c/c9/43/77/DM00105262.pdf/files/DM00105262.pdf/jcr:content/translations/en.DM00105262.pdf

Anyone knows ?

Shall I put test code here :

void MX_FREERTOS_Init(void) {

  /* USER CODE BEGIN Init */

       

  /* USER CODE END Init */

  /* USER CODE BEGIN RTOS_MUTEX */

  /* add mutexes, ... */

  /* USER CODE END RTOS_MUTEX */

  /* USER CODE BEGIN RTOS_SEMAPHORES */

  /* add semaphores, ... */

  /* USER CODE END RTOS_SEMAPHORES */

  /* USER CODE BEGIN RTOS_TIMERS */

  /* start timers, add new ones, ... */

  /* USER CODE END RTOS_TIMERS */

  /* Create the thread(s) */

  /* definition and creation of defaultTask */

  osThreadDef(defaultTask, StartDefaultTask, osPriorityNormal, 0, 128);

  defaultTaskHandle = osThreadCreate(osThread(defaultTask), NULL);

  /* USER CODE BEGIN RTOS_THREADS */

  /* add threads, ... */

  /* USER CODE END RTOS_THREADS */

  /* USER CODE BEGIN RTOS_QUEUES */

  /* add queues, ... */

  /* USER CODE END RTOS_QUEUES */

}

/* StartDefaultTask function */

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 */

  for(;;)

  {

    osDelay(1);

  }

  /* USER CODE END StartDefaultTask */

}

/* USER CODE BEGIN Application */

     

/* USER CODE END Application */

How can I add new task ? and why STM32 suggesting me not using SYSTICK but use TIMER ?

#stm32f1 #sdcard #usb-fs #rtos #sdio

I would start by increasing the stack size in your 

osThreadDef to 512 (or higher) and see if that makes a difference.  Invariably I have to increase the stack size in the default task when using USB CDC.

I use GCC as my compiler. When I'm in doubt about whether this is a problem, I have GCC dump stack usage statistics (-fstack-usage) for analysis.

Stack usage is what trips me up most when doing RTOS programming.

Does it matter with init code if it's outside RTOS ?

Or have conflict between SDIO interrupt and RTOS interrupt ?

Thanks
