I can help you with these things.  However, I think you'd be best
served by upgrading to use RedBoot instead.

RedBoot is our new embedded debug and bootstrap environment.  Based on
the eCos HAL, it provides all of the functionality you are looking for
and much more.  Even though it is already available via anonCVS, it
will be formally announced [and shown off] at ESC West later this month.
