Another thing I just noticed - this implies that you're trying to build
your "hello" application to run from ROM.  You probably want one that 
runs from RAM *and* you'll want to start from a configuration that 
includes the basic eCos kernel.  Note: this is *not* the same kernel
configuration that you used to build RedBoot.

Check the documentation or look at my examples at: http://www.mlbassoc.com/examples/
