Hi Frank.
There you can find an example of work with SD MMC cards.
http://www.siwawi.arubi.uni-kl.de/avr_projects/arm_projects/efsl_arm/index.html
".....Memory-cards like SD-Cards or MMC offer a huge amount of memory
and are relativly cheap. SD-Cards and MMC can be accessed in SPI-Mode
so only 4 data-lines are needed to connect such cards to a
microcontroller (chip-select, MOSI, MISO, SCK). To read and write data
from/to the card with a "standard"-PC a filesystem is needed......"
Best Regards,
Nikita
