STM32F429ZI FATFS issue

Hello,

I'm trying to use FatFS with both USB HOST MSC class and SDIO.

FatFS always tries to access the SD card whatever the drive number used in f_mount.

May be I'm wrong with the path I use to access the devices : "0" for SD card, "1" for USB.

Any help will be welcome.

Issue is solved.

I stepped into f_mount and found thaht the path was missing the ":" i.e. path must be "0:" or "1:" not bjust "0" or "1".

Thanks for the answer :)
