[ARMedslack] ARMedslack hangs during boot on Dreamplug

[Jim Hammack]

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:

Marvell>> version

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
