Hi,

I've a problem with my STM32. I need to use fat filesystem on SD card to read/write/create files.

I tried to use Chan FatFs module but it didn't working at all ...

I use SD card in SDIO and 4 wires mode.

When I debug, check_fs() function can't retrieve 0x55 0xAA on boot sector, but, when I read sector n�0 in the main(), I can correctly read all datas on boot sector.

If someone can help me with this problem ...

Thanks.

Hi @Cesar cfg ,

Though long time since you posted...

I'm facing the same problem when dealing with F103 MCU. Can you please share the changes you made in file diskio.c (disk functions)?

Thanks,

Aviv
