Dear Giovanni,

On fact my troubles not cleared, but first at all question:
Are you has planed upgrade FatFs to current FatFs R0.10a with according m ?
I check: enough in chibios-os-various in fatfs_diskio.c in functions disk_read and disk_write instead "byte count" write "UINT count".
And in end ...

Giovanni,

Thank you.
Problem resolved.

I found m - running directly via SPI. (the same solution + with DMA (explained on russian) - m ) -> All this working directly via SPI.

What is correct sequence how to initialize MMC over SPI2 and receive maximum performance?

SPI2 connected to MMC: PB13 - SCK, PB14 - MISO, PB15 - MOSI, PD11 - CS, 3.3v

I try to show clear code - please specify where mistake or something lost:

Dear Guru,

I'm novice in this OS and desk STM32F4Diskovery and ask your help.
I write a LOG module for save my logs to MMC card over SPI2 (target twice per second).
I learned a lot of samples (OS, Japan guru, other) and found good feedback about MMC over CSD or MMC over SPI in DMA mode.
What i have ...

I made a big update.
This requires FatFS 0.9b which has added get/set label.

Are you update require updated files in ChibiOS_2.6.1\os\various\fatfs_bindings ?
Can you share?
Last actual Chan version FatFs is R0.10a, but in os we have 0.8

P.S. SDC & MMC interface look like the same.
Now i write ...
