this question was asked by others also on devel.
I simply used these steps:

Open Terminal 1:

$ sparc-rtems5-sis -gdb

        # It will print 'gdb: listening on port 1234'.

        # Note you can define port number with '-port' option.

Open Terminal 2:

$ sparc-rtems5-gdb hello.exe

        # gdb asks for several inputs

                $ target extended-remote localhost:1234

                $ load

                $ r

You will see output in Terminal 1.
