So the architecture is the IXP2400.
I have ported the Intel redboot to the current ~2.0 code(pre-release CVS). I
have it running (ROMRAM) from flash. My application works booting redboot
from flash and loading the application. However, when I click the "Behave as
ROM monitor" (to make standalone app) it changes my startup type to ROMRAM.
Which I assume is not what I want.
thanks,
Aaron
