Posted on September 10, 2016 at 12:37Hi every body.
i configure STM32CubeMX to write on SD card. im using stm32f7 discovery board. i set SDMMC on ''SD 4bit wide bus'' and enabled FatFS for SD card.
my main function is :
int main(void)
{
/* USER CODE BEGIN 1 */
/* USER CODE END 1 */
/* MCU Configuration----------------------------------------------------------*/
/* Reset of all peripherals, Initializes the Flash interface and the Systick. */
HAL_Init();
/* Configure the system clock */
SystemClock_Config();
/* Initialize all configured peripherals */
MX_GPIO_Init();
MX_SDMMC1_SD_Init();
MX_FATFS_Init();
/* USER CODE BEGIN 2 */
/* USER CODE END 2 */
/* Infinite loop */
/* USER CODE BEGIN WHILE */
if(f_mount(&SDDISKFatFs, (TCHAR const*)SD_Path, 0) != FR_OK)
{
/* FatFs Initialization Error */
Error_Handler();
}else
{
if(f_open(&MyFile, ''STM32.TXT'', FA_CREATE_ALWAYS | FA_WRITE) != FR_OK)
{
Error_Handler();
}
else
{
res = f_write(&MyFile, wtext, sizeof(wtext), (void *)&byteswritten);
if((byteswritten == 0) || (res != FR_OK))
{
Error_Handler();
}
}
f_close(&MyFile);
}
while (1)
{
/* USER CODE END WHILE */
/* USER CODE BEGIN 3 */
}
/* USER CODE END 3 */
}
after debug i found code hangs on f_open(&MyFile, ''STM32.TXT'', FA_CREATE_ALWAYS | FA_WRITE)
is there any thing more to do , to make it work ??
any help or suggestion would be appreciated.
Thanks in advance
MA.
