Once the eCos application takes over, the RedBoot command line can't be used.

If you connected to RedBoot using GDB in order to load and run your 
program you can interrupt it while it's running - that's because the eCos 
build will permit RedBoot to take over for the purposes of GDB debugging.

I think for what you want to do, using GDB will work best for you.
