[Xenomai-help] Booting fails: Kernel panic

Hello everyone,

 

i thought that it would be better if i started a new thread for this:

 

I have some trouble with getting xenomai to run on a PC/104 device with AMD
Geode GX processor (Debian 4.0 is installed). My development platform which
is running a Athlon64 (with Kubuntu 6.06) is already doing fine. For testing
purposes i tried using the same kernel-bulid (2.6.20.11 kernel with 2.3.1
xenomai) for both by selecting a 486-processor in the menuconfig. It works
on my Athlon64 but on the PC/104 after copying the files i cannot boot. On
the first boot it said directly that xenomai failed to load (and all the
RT-interfaces after that).. all with errorcode -19. I am not able to
reproduce that output, though. After that i turned off APIC to see if it
changes something and then i got further in the boot process but now
stopping with:

 

/bin/dash: error while loading shared libraries: libc.so.6: cannot open
shared object file: No such file or directory

 

Now it does not seem to change anything whether the ,noapic' parameter is
passed to the kernel or not, though. This is all kind of strange, because i
already had xenomai running successfully on that platform, but i am not able
to get it running again.. (in other kernel building attempts the system
booted but xenomai was not loaded (in /proc was no xenomai folder) and yes..
i did boot the right kernel). 

 

The PC/104 has a 500Mhz AMD Geode GX processor and 512MB Ram. It uses a 1GB
Flashdisk that is plugged in via the IDE port (shows up as hda). To build
the xenomai-kernel i modified the config from the running Debian 4.0 system.

 

Could a problem stem from the fact that i copied the files to that machine
and did not build them on the same machine?

 

I really hope someone can help me with this.. 

Thanks in advance!

 

Jonas

Do you happen to use i686 libs on your Geode, instead of i586? Check
what your distro installed.
