<font size="2">Hi,</font><br /><font size="2"><i>I
have downloaded the 2.6 kernel from </i><a class="fixed"
href="http://git.secretlab.ca/git/linux-2.6-virtex.git"
target="_blank">http://git.secretlab.ca/git/linux-2.6-virtex.git</a> , installed
& compiled it. I used "make
ARCH=ppc CROSS_COMPILE=ppc_4xx- ml403_defconfig" to build the .config file.
(As explained in <a class="fixed"

-</b><br /><p><font size="2">1)Downloaded(sourceforge.net) & compiled the
U-boot 1.1.6 files to get u-boot, u-boot.srec & u-boot.bin (I didn't find
ml403 board config for the uboot. So used ml300_config). </font></p><p><font
size="2">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?</font></p><p><font size="2"><i>$ xmd

tried to search the net for an u-boot ace file that could run on ML403 &
found it at

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.</font></p><p><font size="2">But, it
failed in both cases. (There was a previous post on Problem2 a year ago & he
solved it by giving root =/dev/xsysace2)</font></p><p><font
