1. Link the start-up code, stub and drivers needed by it to a binary
package.

2. Load the package to the target system using whatever means available
(Flash / PROM burner, JTAG debugger etc.).

3. Link the application with the drivers & libraries it needs. The linker
script shall direct the target to RAM not used by the stub.

4. Connect the target with the stub to the controlling computer with GDB,
and start the target and GDB.

5. Set GDB to remote mode to the target and download your application with
it.

6. Start up and debug your application with GDB.

Been there - done that (using ARM7TDMI, Atmel At90R40800).

PS. At least I had quite a lot of debugging before the stub worked
properly - luckily GDB has commands to debug the remote protocol, too.
