Hi all, i'm sorry if this has been discuss before, but from reading posts i'm still some what unclear, thus my post.

Has anyone implemented reliably SDIO using DMA along with say FatFS file system ? 

There seems to be alot of comments around interrupts and delays when setting DMA, and thus creating a race/lockout.
