Are you using the precompiled binaries available from 
http://sources.redhat.com/ecos/boards/ipaq.html ?

Once you know you've got something working, then you will probably find it
easier to rebuild and be sure there aren't any problems with e.g. your
tools etc.

It looks what you are describing is that you are using the build tree
configured with "ecosconfig new ipaq redboot" to build your applications.
This isn't right - the redboot template is used solely for building redboot
itself. Instead start with a new clean build tree and just use a default
configuration like:

ecosconfig new ipaq
ecosconfig tree
make

In fact then do:

make tests

which will build some test applications under install/tests/ which you can
try out on the board, which may help avoid any pilot error in building the
hello world example.

Do recompile RedBoot you must use the redboot template only. Make sure you
are using a new clean build tree when you build for a different template. 

I take it you are following the instructions in the RedBoot user's guide on
installing for the ipaq, of course.
