[oe] Openembedded for AVR32

[Robert Wörle]

   I had similar issues once.
   To me it was the problem that my busybox was not compiled with a
   compatible toolchain then the kernel.
   I used to compile the kernel via atmels but my rootfs was done by oe.
   Atmel by then already used uclibc-0.9.29 where oe was still using
   0.9.28 ..

Hi,

Does OE for AVR32 really work?

I had a working version about two month ago from the monotone repository.

For about three weeks we try to get it running from the latest monotone reposito
ry and after the
transition to git from the latest git.

Just as of this morning I grabbed a fresh new clone from the git repository.

OE does compile (minimal-image). But I can't boot the image.

This is what I found out.

** Kernel **
OE Kernel does boot. We included a newer version (2.6.25.10) into OE with our ow
n patches. This version does boot as well.
Tested on ATNGW100 and our own hardware.

** rootfs **
Rootfs is mounted via NFS. From the server logs I can see, that the filesystem a
ctually is mounted. See the last lines from my bootlog:

init has generated signal 11 but has no handler for it
Kernel panic - not syncing: Attempted to kill init!
-------

There is always a signal 11 in init (seg fault).

** init **
We tried different init.
 - OE default sysvinit => segfault
 - Busybox init => segfault
 - No init => kernel tries to load sh => segfault
 - Our own "hello world" app (compiled outside of OE) => segfault

Can anyone confirm that OE for AVR32 does work?
How can we debug and fix this problem?

Thanks

Alex
