Well, yes. Although I thought you wanted to go straight to running your
application from ROM. You would have to set your configuration not to
believe a ROM monitor is present though. And if you want debugging, you
would have to include GDB stubs in your app.

But porting RedBoot is as easy as porting eCos. It uses the same HAL as
eCos after all! It's probably easier to port RedBoot as you'll have to do
more or less the same work when porting eCos.

Yes.
