I used the examples fatfs_sdcard and fatfs_mmccard of the SDK 2.x and there is no way to work, always say FR_NOT_READY when try f_mkdir() call.
I don't know how to follow, thanks for ryour help.
It was a question of the way to put the card into the socket, it should be do it very smoothly.
Were you able to resolve this? Do you have any other questions?
OK, the problem is solved, thanks.
