I'm still a bit confused. 

Can I use redboot_ROM.ecm for my application? 

i.e.

ecosconfig new eb40a default
ecosconfig import ...../hal/arm/at91/eb40/misc/redhat_ROM.ecm
ecosconfig tree
make

voila! I can now create application images that I can upload via
my recently installed Redboot. 

Or...


Recap of my goals below:


- I want Redboot in flash. The user never upgrades Redboot. I believe
I have correctly configured and built Redboot. Worked when I tried
the ram version last week. (I'll test more next week.)
- I'd then use Redboot to write the application to flash
- I had planned to create a startup script with a "go" command w/a
delay.
- If the user needs to reprogram the application, he'll reboot,
abort the startup script "go" command and write the application
to flash. (Most likely we'll write a small app for this, I just
recently put together a xmodem, ymodem, zmodem uploader using 
lrzsz that I'm using from my Java program.
