Posted on May 12, 2016 at 13:55Hello!
I try to use the SDMMC1 interface together with FatFS. Initialization is created with CubeMX.
My init is something like this:
...
MX_LTDC_Init();
MX_SDMMC1_SD_Init();
MX_FATFS_Init();
...
Then I try to use the SD card. The CardInfo is right, I get data from. But with the FatFS I got some problems. Initialization and f_mount is no problem but then I get uSD: FatFs format Error with the Error code 3 -> NOT_READY
UG_ConsoleSetForecolor(C_YELLOW);
UG_ConsolePutString(''System start uSD debugging...!\n'');
if(HAL_SD_Get_CardInfo(&hsd1, &SDCardInfo1) != SD_OK)
{
UG_ConsoleSetForecolor(C_RED);
UG_ConsolePutString(''uSD: HAL_SD_Get_CardInfo != SD_OK!\n'');
Error_Handler();
}
// Put infos about SD card
UG_ConsoleSetForecolor(C_WHITE);
sprintf(itoaBuffer, ''SD capacity: %d\n'',SDCardInfo1.CardCapacity);
UG_ConsolePutString(itoaBuffer);
sprintf(itoaBuffer, ''SD block size: %d\n'',SDCardInfo1.CardBlockSize);
UG_ConsolePutString(itoaBuffer);
sprintf(itoaBuffer, ''SD type: %d\n'',SDCardInfo1.CardType);
UG_ConsolePutString(itoaBuffer);
/*♯♯-2- Register the file system object to the FatFs module ♯♯♯♯♯♯♯♯♯♯♯♯♯♯*/
FRESULT tempRes = f_mount(&SDFatFs, (TCHAR const*)SDPath, 0);
if(tempRes != FR_OK)
{
/* FatFs Initialization Error */
UG_ConsoleSetForecolor(C_RED);
sprintf(itoaBuffer, ''uSD: FatFs Initialization Error (%d)\n'', tempRes);
UG_ConsolePutString(itoaBuffer);
Error_Handler();
}
else
{
/*♯♯-3- Create a FAT file system (format) on the logical drive ♯♯♯♯♯♯♯♯♯*/
/* WARNING: Formatting the uSD card will delete all content on the device */
tempRes = f_mkfs((TCHAR const*)SDPath, 0, 0);
if(tempRes != FR_OK)
{
/* FatFs Format Error */
UG_ConsoleSetForecolor(C_RED);
sprintf(itoaBuffer, ''uSD: FatFs format Error (%d)\n'', tempRes);
UG_ConsolePutString(itoaBuffer);
Error_Handler();
}
Do I have to do something else after the init from Cube? I am a bit in trouble with the FatFS...
Would be great if someone has an answer for me!
