U-boot 1.1.6 is ancient. The u-boot project has moved off of
sourceforge to denx.de
After this, I tried to convert the u-boot (README says that this is an ELF
file) into an ace file. But, it gave me the error saying unable to read elf
file. Is it because ML403 board is not supported or is it possible that the
u-boot image that I created is corrupted?
I don't know; but personally I don't weld u-boot into an ace file. I
use a 1st stage bootloader to load the u-boot image off the cf card
(but unfortunately I'm not able to post that loader at this time).
Try again with a recent u-boot version.
2) Since generating ace files failed, I tried to search the net for an
u-boot ace file that could run on ML403 & found it at
http://88.191.24.164/docenligne/projets/samba/2006/linux-embarque-sur-ml-403/u-boot-ml403.ace/view
I copied this ace file (u-boot-ml403.ace) along with the kernel 2.6 image
(uImage) onto my CF card & booted the board. After loading the kernel, it
fails to read the correct root device. I tried changing the "bootargs" env
variable root = /dev/xsysace/disc0/part2 rw to root = /dev/xsysace2 rw &
root = /dev/xsda2 rw.
But, it failed in both cases. (There was a previous post on Problem2 a year
ago & he solved it by giving root =/dev/xsysace2)
Looking at your bootlog, it doesn't look like you've got the systemace
driver built into the kernel.
Cheers,

Grant,
Yes, the systemace was not built into the kernel. It is successfully
booting the kernel now.
Trying to bring up the Ethernet interface. Any pointers?
Thank you,

Do you really need u-boot??
I'm using an ML403 without u-boot. I've generated my .ace file with the
zImage.elf directly and it works fine.
If there is a choice of u-boot or not, why choose u-boot?

Hi,
Goal - To use the USB Host on ML403 in a PowerPC processor reference
system to store some data on a Thumb Drive.
Background - I downloaded the 2.6 kernel from
http://git.secretlab.ca/git/linux-2.6-virtex.git , installed &
compiled it to get uImage & zImage.elf files. I used "make
ml403_defconfig" to build the .config file. (As explained in
http://wiki.secretlab.ca/index.php/Linux_on_Xilinx_Virtex)

If you're starting a new design, I *highly* recommend using EDK9.2 with
MPMC3 and LL_TEMAC.
Using the Wizard in EDK9.2 and using the kernel from git.xilinx.com
everything will work fine out-of-the-box. Including the ethernet.
I've had troubles with the older (EDK9.1) TEMAC and GigE switches not
syncing correctly. The LL_TEMAC in EDK9.2 solved this issue.
