[Buildroot] eabi for ARM9

[Konstantin Kletschke]

Hi Folks!

Actually I am trying to get an eabi Userspace environment running with
2.6.18 and eabi. This is due to the fact that I want to upgrade my
gcc-3.4.6 to gcc-4.x with softfloat support wo hardware FPU. The
gcc-4.x toolchain with this option enabled only compile with
BR2_ARM_EABI=y. So I have a toolchain now with gcc-4.1.2 and
uclibc-0.9.29 (snapshot). The kernel compiles fine, I chose 2.6.18
with 

CONFIG_AEABI=y
CONFIG_OABI_COMPAT=y

enabled.

But my userspace bails out with "Illegal instruction". What I found
out is, that busybox run as init process puts out its compiled in
programs and disclaimer, but running /bin/sh (configured as standalone
shell) gives no output anymore.

Is this combination of software to be known to work?

Additional queston is: Is it possible to use an old ABI compat kernel
and chroot with it from non EABI userspace into EABI userspace or
can't this work?

Regards, Konsti
