This tells me that you tried to build the 'hello' program for ROM mode.
You need to have a startup type of RAM in order to load & run via GDB.

The most likely reason for this would be that you tried to reuse a
configuration which you used to build RedBoot to build the application.
This is not correct.  You must have a new configuration (build directory,
etc) for a new environment, namely RAM based applications.
