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
