[Scratchbox-devel] Big endian kernel and applications on a IXDP465

[Jussi Hakala]

I'm assuming you are creating the environment from scratch, so you don't
have an actual target environment to try your compiled binaries with to
test if it was a problem with your big-endian qemu.

Can you be more specific about the problem, ie. what was the simple
program and what was it's output?
