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
