Please send your questions to u-boot ML. It is the right place where we
can exchange experience on u-boot.

If this is the u-boot you find in the ltib, the command could be
correct. It depends how u-boot is built.

The MX51 processor reads automatically the SD card starting from address
0x400. At this address, the processor must find the DCD table.
In the patches I sent, I follow another approach: u-boot is build
independently from the device where you will store the bootloader. You
have to generate u-boot.imx (with "make u-boot.imx"), that adds the DCD
table and then you must store it at the correct offset. On a SD card,
this means with:

	dd if=u-boot.imx of=$(SD_CARD) bs=512 seek=2

Do you try the patches I sent to the ML ? And which is the version of
your processor (TO1, TO2 or TO3) and of the board ?

Best regards,
Stefano Babic
