Bytes. And of course you can still reduce it substantially using
configuration.

You can't download something into ROM! You have to use a ROM or Flash
programmer of some sort. Or if you are using Angel, you have to program it
into ROM using its routines. This would be done the same way you programmed
RedBoot into ROM as per
http://sources.redhat.com/ecos/docs-latest/redboot/at91.html

So do it by downloading and running a RedBoot RAM image first, then loading
and programming your application ROM image.
