When you start up gdb, see if it accepts the following command:
(gdb) target sim
If it does, then it has a CPU instruction set (not peripherals)
simulator. You then have to load the application and run it. You
usually have to use a linker command file that's compatible with the
simulator. Hopefully someone else here knows more about this than me!

If you look at an srec file with your text editor, you'll see that
it's an ASCII representation of your binary data. As such, an srec
file is at least twice as large as the binary data it represents. So a
33k srec file contains about 16k of data.
