And some fun thnigs - autogenerated code for SDIO mode ''SD 1 bit'' have HardFault, then i try to use f_open
My example:
FATFS FileSystem;
uint8_t DiskPath[4];
FIL LogFile;
if(retSD==0)
{
printf(''Link MicroSD Driver:\t[OK]
'');
if(f_mount(&FileSystem, (TCHAR const*)DiskPath, 0) != FR_OK)
{
printf(''Mount file system:\t[FAIL]
'');
}
else
{
printf(''Mount file system:\t[OK]
'');
if(f_open(&LogFile,(TCHAR *) ''log.txt'',FA_CREATE_ALWAYS | FA_WRITE) != FR_OK)
{
printf(''Opening file:\t[FAIL]
'');
}
else
{
printf(''Opening file:\t\t[OK]
'');
uint32_t byteswritten;
if(f_write(&LogFile,''Hello world'',sizeof(''Hello world''),(void *)&byteswritten) != FR_OK)
{
printf(''Writing:\t\t[FAIL]'');
}
else
{
printf(''Writing:\t\t[OK]'');
printf(''Writed %d bytes
'',byteswritten);
if(f_close(&LogFile) != FR_OK)
{
printf(''Close file:\t\t[FAIL]'');
}
else
{
printf(''Close file:\t\t[OK]'');
}
}
}
}
}
else
{
printf(''Link MicroSD Driver:\t[FAIL]
'');
}
As i know - in file ff.c (f_open function) at string №2446
res = find_volume(&dj.fs, &path, (BYTE)(mode & ~FA_READ));
after thet string pointer to hsd->Instance will be modifed (hsd->Instance must bee 0x12C00, but after this function it have value 0xA)
Tested at STM32F4Dicrovery with DM-STF4BB extation board (microSD holder and etc.)
