O.K. I forgot this was RedBoot. Redboot means no kernel, which also
means no real SMP usage since it is single threaded. I don't think the
second CPU will be started.

So i would suggestyou just use a UP Redboot. You can then look at SMP
eCos applications which are booted via Redboot. I guess that is what
you are really interested in.
