Hi,
I'm working on booting kernel 2.6 on Xilinx. And I'm encountering a few
problems.=20
1. When I directly download zImage.elf to the RAM and boot from there, I =
see
the kernel starts booting, but it complains about not being able to =
mount
/dev/sysace/disc0/part2 and thus kernel panic happens.
The following is the output

2. When I tried to boot the zImage (sitting in the flash) from u-boot =
file
(generated from the same source code as uImage.elf), as soon as it gives =
the
control to the kernel, no messages would come. I checked to make sure =
that I
had the right serial port setting (console=3DttyS0,9600), but still =
nothing
shows up.
Here's the output of what I had (I turned on some extra debug msg in =
u-boot)

3. Lastly, whenever I issue a reset command in u-boot, it just locks up =
and
hangs. I have to do a hardware reset every time. I'm wondering if the =
reset
vector is going to a wrong place. How would I check that?
I'm fairly new to the whole embedded domain. Please feel free to help. =
It
would be much appreciated! Thanks.

When you use U-Boot, you should use the correct image (uImage).

Try this:
mount the CF card onto your PC and then goto the /dev folder on your
root filesystem in the card. Here run the following commands as root:
# mknod -m 660 console c 5 1
# mknod -m 660 xsa b 254 0
# mknod -m 660 xsa1 b 254 1
# mknod -m 660 xsa2 b 254 2
# mknod -m 660 xsa3 b 254 3
Now there should be a directory tts in your dev. If not create one
"mkdir tts". Then do this in the dev/tts folder,
# mknod -m 660 0 c 4 64
If you don't need CF card at all, the easiest method to solve it is to
remove it from the linux kernel configuration.
Regards
Ming

Can u-boot access the systemace CF?
Do the kernel statup messages show that the system ace driver is loaded
and has successfully initialized? I don't see this in your boot message
dump.

Sorry ,that was a typo, I did use "uImage"
Thanks,

Wolfgang, Aleck,
I think this patch
http://ozlabs.org/pipermail/linuxppc-embedded/2006-August/023912.html
explains the inability to use u-boot for the ml403 (and ml3xx) for the
2.6 kernel.
