Re: Re: New User - Help!

I think the demo that comes with the Axiom board is intended to be used 
with their monitor utility. I think thats fine if you plan on using the 
monitor utility, but if not, you should use something like the demo that 
comes with the Diab or CodeWarrior compilers. They make no assumptions 
about what might already exist on the target.
