I have a problem with FATFS
I am working with STM32F407 Discovery Board and micro SD Card. I use STM32CubeMX version 4.23 to config SDIO 4 bit.
This is my code to read data from micro sd card:
FATFS myfatfs;
FIL myfile;
uint8_t SD_Data_Read_Arr[100];
uint32_t readbyte;
/* USER CODE BEGIN 2 */
if(BSP_SD_Init()!=MSD_OK){};if(f_mount(&myfatfs,'',1)!=FR_OK){};if(f_open(&myfile,'123.txt',FA_READ)!=FR_OK){};if(f_read(&myfile,SD_Data_Read_Arr_1,100,&readbyte)!=FR_OK){}; /* USER CODE END 2 */while(1)
{
}
I load my code into MCU and debug by Kiel C. Then I observe SD_Data_Read_Arr in watch1 monitor.
I have two micro SDCard. One is Transcend,SDHC ,16GB and one is China's item( It do not have manufacturer),2GB.
I connect micro sd card to MCU through SD socket.
When I use 2GB micro sd card. My code was run and I can see data of SD_Data_Read_Arr in watch1 monitor.
But when I use 16GB micro SDcard. SD_Data_Read_Arr do not have any data. I get error in f_mount(&myfatfs,'',1) is FR_NO_FILESYSTEM.
I have some question:
1. Why can't I work with SDHC
card?
2. How can I solve this problem?
3. When I use STM32CubeMx, how can I config to work with all SDcard type?
Thanks for any help! If you need, I can upload my project...
