Dear Schleifer, Alexander,
Hello Reinhard,
thanks for your reply.
I checked the register settings and sorted out, that the SDCBUS was
initialized in 4-bit mode by the bootstrap.
So I added the explicit initialization when port A is used:
#if defined(CONFIG_ATMEL_MCI_PORTB)

Hi Alex,
Thanks to Reinhard
Dear Schleifer, Alexander,
But I found out, that the AT91Bootstrap initialization impacts
the U-Boot code. If I use the AT91Bootstrap (without mci initialization)
from NAND flash, the mmc init command successfully reads the card.
It fails if I use the AT91Bootstrap with mci initialization.

This patch adds support for the Atmel MultiMedia Card Interface (MCI)
in AT91SAM9260 and AT91SAM9XE SoCs and preserves the original support
for the AVR32AP700x SoCs.
It patches the original atmel_mci.c driver to remove byte order and
toolchain dependencies and makes it a common MCI driver for

Hi Reinhard,
To format the SD card, I did following

# dd if=/dev/zero of=/dev/sdc bs=512 count=10
# mke2fs /dev/sdc
# mount /dev/sdc /mnt/ext2disk

I guess you tested fatls or fatload or fatinfo or ext2ls,

Hi Reinhard,
In Linux, I used `fdisk' to cerate 2 primiary partitions on SD card, each is
about 1G bytes.
I used `mkfs.ext2 /dev/sdc1' and 'mkfs.ext2 /dev/sd2' to format the 2
partitions and then copy some files on them.
I used SanDisk 2GB SD Card.
But in U-Boot,
