In general it's right the same as with the at91sam7x256. The CPUs only
differ in the size of RAM and Flash.

A what stage the mounting fails? Just when registering the MMC devices
or does the _open() call fail? 

Have you FSCHECKed your sd-card?

Which NutOS version do you use? With the latest Nut/OS versions I added
a special spi-bus mmc glue logic device driver (nut/dev/spi_mmc_gpio.c).
Do you use this driver?

What errno is given?

Do you have connected any further SPI devices to the same SPI bus?
