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?
Bye,
Ole
