Hi ,
I am working on ixp2800 and trying to bring it up using SNAPGEAR.
I have SNAPGEAR 3.2.0 and arm-linux-tools-20031127.tar.gz as my tool
chain.
I got a zImage using default setting for ixp2800, and linux 2.4.x
kernel.
I am able to launch it and insert modules using insmod. But when I try
executing it using the ./sa executable it reports the following errors.
=================================================================

I desperately need guidance to continue.
