Things are easier if you send only plain ASCII messages.

linkcmds -- all code, data/bss in RAM.
linkcmds.prom -- code in ROM, data/bss in RAM -- data segment is placed
in ROM after code section; the startup code is responsible for copying
the data to RAM.
linkcmds.bootp -- similar to linkcmds.prom, but the data/bss sections
are place high in RAM; intended for bootstrap ROMs which load
executables into low RAM.

Be default, the RTEMS Makefiles use linkcmds.  Have a look at how the
sample applications (hello, etc.) qre built.
For an example of the use of linkcmds.bootp, download
