I try tomorrow record Debian "Stretch" U-boot/uImage/uInitrd -terminal 
output with instructions 
"https://www.cyrius.com/debian/kirkwood/sheevaplug/install/;


Sorry delay, I have to load new binaries to GuruPlug and I'm not very 
familiar with unix command line scripting, readable minicom -output 
needs little tee/sed processing.

not very handy to make commad line scripting, terminal output

Ok, I didn't notice the version of u-boot from the log you posted and
went on what you wrote.

However, looking at the log file again, I notice you're loading the
DTB file separately.

You say you follow my installation instructions but clearly you're
not.  In Debian installer, for the various plug devices, we append to
the DTB at the end of the kernel rather than loading it separately.

Can you please follow the instructions at
https://www.cyrius.com/debian/kirkwood/sheevaplug/install/ and post
the output of that?

Bug#891857: busybox: Special case for /32 subnets not working as expected

[Yuval Freund]

Package: busybox
Severity: normal

Dear Maintainer,

Many of our customers would like to use the debian installer in order to set up 
their own VMs. Our DHCP servers currently offer addresses with /32 subnets, and 
we've come to realize that the debian installer does not properly configure the 
default route.

A fix for /32 has already been implemented in an earlier version of busybox, 
but it doesn't seem to work as expected, because the interface isn't defined 
while adding the relevant route.

Here's a suggested fix, which would probably also clear up what I mean:

We would appreciate it if you could patch all current/relevant versions to use 
this fix.

Thank you!

Sorry, english is not my native language (I'm finnish), so I have been 
unclear on my previous posts.


I have followed instructions literally, but installer freezes and text 
"Uncompressing Linux..." appears on terminal window.


On "https://www.cyrius.com/debian/kirkwood/sheevaplug/install; separate 
ftd -blob file is indeed not loaded, but when I load fdt kernel

finally boots but cannot find rootfile system.

There is some information on "Debian armel installation" guide for 
uInitrd relocation problems and advice to se "bootm_size" to default 
value.
Unfortunatelly that does not work if original U-boot version is 
pre-2014, becouse of bootm_size value is not set at all. I tried to se 
"bootm_size"
value manually by U-boot without success, only way to get kernel to boot 
is load fdt separately.

I'm using Debian stretch U-boot version (U-boot version number is

Flattened device tree -mechanism is not using those "ATAG" global

I've never had a GuruPlug so I cannot really comment but why are you
using the pre-2014 u-boot version?  I cannot remember all the
differences of the u-boot versions of the installation page says you
should upgrade your u-boot before installing Debian.  Maybe you can
give this a try.

Based on the logs you posted, it seems to me that the kernel and
ramdisk are loaded but the kernel doesn't see the ramdisk, leading to
the "no root" issue.

Armel: Debian installer freeezes (GuruPlug Server plus)

[Kari Tanninen]

HW: Guruplug Server plus with JTAG-box (ARMv5-family)
Debian U-boot version: Armel stretch (buster u-boot version freezes when 
setting ethact IP-addresses), original U-boot pre-2014

Debain Installer version: stretch


Problem: When trying to launch d-i (stretch, with instructions 
from Martin Michlmayr webpages) from USB-stick or memory (tftp-load), 
installer freezes with text "Uncompressing Linux". Original U-boot 
version pre-2014 has a documented bug with old u-boot versions variables 
(bootm_size value). Setting initrd_high/fdt_high 0x to fix 
doesn't help.


When FDT-blob loaded to fix problem(addres 0x0c00)kernel founds fdt 
and uInird and starts obviously normally but won't read command line 
parametres from fdt-memory area as should (using original default fdt 
instead), and cannot find root file system (on default fdt-file root 
filesystem is not defined).


Seems that U-boot sets and finds command line parametres to/from fdt 
normally, but kernel doesn't use it. (maybe d-i kernel configured for 
statical fdt?)


Reference: Globalscale Fedora 11 (+ OpenDC) development package works 
and installs (unfortunatelly very old) system without major problems 
(minor changes with MAC-address space defaults to perl script needed) -> 
HW probably OK


Is there any fix-up/work-aroud trick available or is new kernel 
compiling only option?
