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,
