All,
Thanks for all of the suggestions. I was able to get the system
booted by flashing the original u-boot (U-Boot
2011.06-02334-g8f495d9-dirty (Mar 28 2011 - 05:21:06) - which does not
support ext2) and installing an older version of armedslack which uses
kernel 2.6.38.4. I replaced uImage-kirkwood with dream-2.6.38.4-uImage
to get around the problem pointed out by Innes earlier with MTD support
causing the boot sequence to hang on dreamplugs. The older kernel is
not really a problem for me and it matches what I'm running on my
Sheevaplug anyway.
So it appears that my problem was caused by the version of u-boot I
was trying to use (to get ext2 support) and not by incorrect
environmental variables or by corrupted files.
I had one problem after following the instructions in
INSTALL_KIRKWOOD.TXT. I created a FAT16 /boot partition as Stuart
suggests in the documentation and specified that partition for /boot
during installation, but the Slackware installation did not write /boot
there for some reason. So I had to reboot via tftpboot and copy the
files from my ext4 partition to the FAT partition. I'd like to use ext2
for the boot partition (FAT apparently does not support symbolic links),
but at this point I'm afraid of bricking the box again by trying to use
another version of u-boot that supports ext2. If anyone has been
successful with that, I'd like to find out the secret!
Thanks,
Jim

I've been trying to install ARMedslack on my Dreamplug (ser:
1148-XXXXXX) by following Stuart's excellent instructions in
INSTALL_KIRKWOOD.TXT, but have been unable to get the system to
boot. I believe it is due to a problem with my u-boot which I
scrambled earlier. I have been able to find only one version of
u-boot that will run on this machine (the guruplug version from
http://www.armedslack.org/maint_kirkwooduboot loads but hangs
after a 'reset'). This one works:

pie-0.4.5) 4.4.4
GNU ld (GNU Binutils) 2.20.1.20100303
I am following Stuart's instructions with two exceptions:
1. I am using dream-2.6.38.4-uImage (renamed uImage-kirkwood)
from with-linux instead of uImage-kirkwood from the distribution
due to a known problem with uImage-kirkwood on the Dreamplug.
(http://lists.armedslack.org/2011-August/000978.html)
2. I am using a fat16 boot partition rather that the ext2
partition Stuart uses in his documentation, so I have changed all
references to "ext2load" to "fatload" in the bootcmd
The system loads uinitrd-kirkwood okay, then loads
uImage-kirkwood (which is really dream-2.6.38.4-uImage), but
hangs after:
"Uncompressing Linux... done, booting the kernel."
I don't think this is the problem, but does anyone see any
problems with my u-boot variables? Also, I've read that newer
Dreamplugs (#114 and later) have some differences from the
earlier version. Could this be why the majority of u-boot
versions I've found do not run on this machine? Any ideas on
where I can find a suitable u-boot? I tried the version
referenced here:
(http://www.newit.co.uk/forum/index.php?topic=1977.0) but that
version hangs also.
Any input is appreciated!
Thanks,
Jim
