Hi

I finally got minimal-image compiled in OE for AVR32 and the kernel can 
boot just to the point where it tries to load init.

This will fail with a segfault. Last messages on boot log:

VFS: Mounted root (jffs2 
filesystem).                                          
Freeing init memory: 68K (90000000 - 
90011000)                                 
init[1]: segfault at 00000008 pc 2aaabbe8 sp 7fabbf40 ecr 
24                   
init has generated signal 11 but has no handler for 
it                         
Kernel panic - not syncing: Attempted to kill init!   

I tried NFS boot and boot from flash which both produced the same 
result. I am using U-Boot 1.3.0.atmel.2 (from Atmel buildroot).

Anyone an idea what could be wrong?

To find the problem I did the following:

I have a working rootfs (from AVR buildroot). Booting with OE-Kernel and 
Buildroot rootfs works. I can mount OE-rootfs via NFS and then I can 
execute programs such as sbin/init => this seems to be valid AVR32 
binaries.

I copied init.sysvinit into my buildroot-rootfs. Now the system doesn't 
segfault anymore.

Thanks for any hint

Alex
