Can you send the patch you applied to nand_davinci.c ? That will help to
solve your problem

Subject: Booting and Running Kernel From NAND Flash
Hi,
I'm trying to load and run my kernel from NAND flash but I can't get it
working. I've been following SPRAA0, and I put the patch in create to
partitions in the NAND - mtd0 and mtd1, and I do the ftl_format /dev/mtd1 and
nandwrite -p /dev/mtd0 uImage and it seems to write the image to NAND ok. Then
when I reboot and follow step 8 which says to set bootcmd to 'nboot 0x80200000
0 104000' and the bootargs and autostart and then reboot again. When it boots
up I get the following error:
Loading from device 0: <NULL> at 0x2000000 (offset 0x104000)
** Bad Magic Number 0xffffffff **
I'm guessing the settings for nboot are wrong, that the wrong address is
specified. Has anyone else encountered this problem? Or is there a different
way I can load the kernel into NAND without booting the machinge using TFTP and
NFS and then writing the NAND?
Will T.
