Can anyone please provide me with a link to some basic, low level, 4-bit SDIO interface code compatible with the STM32F4VGT? I'm not looking for it to support a file system(yet), I just want to be able to read bytes from a uSD card. I've seen a few examples out there but I don't understand enough about C to understand all the high level stuff, let alone figuring out how to get TrueSTUDIO to compile it.

Could you tell something on how did you go around that CRC_FAIL in ReadMultiBlocks function ?

If you want someone to answer this you might want to be more specific about what you have wired up, and what you're doing. The forum does not tickle posters, and this thread is 6 months old.
