Hi,

I initialized the SD carte by SPI Protocole and this returned and response no error ( so it's working).

Then i tried to mount the sd card by using f_mount(0,&SD) and this is working too.
But the problem is when i try to access to the sd's directory, i used f_opendirectory and it return an ERROR.

I tried to access to a file on the sd card by using f_open ("file.txt", FA_ALWAYS_OPEN) and this return an error too.
Do you have an idea ?

Thank's.
