I have written some simple code (with the help of STM32CubeMx) for STM32F407VGTx to create a file in SDcard. Although it works perfectly with 407, it is not working with STM32F401ReTx. To be clear, I have generated code with CubeMx specifically for 401(did not use the code for 407).
Even for 407, I am able to work with only Version 21 of CubeMx and firmware version I have added the code below. Any ideas?
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(); /* USER CODE BEGIN Init */ /* USER CODE END Init */ /* Configure the system clock */ SystemClock_Config(); /* USER CODE BEGIN SysInit */ /* USER CODE END SysInit */ /* Initialize all configured peripherals */ MX_GPIO_Init(); MX_DMA_Init(); MX_SDIO_SD_Init(); MX_FATFS_Init(); /* USER CODE BEGIN 2 */ if(f_mount(&myFatFS,SD_Path,1)==FR_OK) { HAL_Delay(1000); f_open(&myFil,'new document.txt\0',FA_CREATE_ALWAYS | FA_WRITE); f_close(&myFil); } /* USER CODE END 2 */ /* Infinite loop */ /* USER CODE BEGIN WHILE */ while (1) { /* USER CODE END WHILE */ /* USER CODE BEGIN 3 */ } /* USER CODE END 3 */}
