Its better if you can give Redboot total control. You are never quite
shore what the other bootloader has setup, and a RAM version of
Redboot cannot totally reset the system. If you can, i would build a
ROM version and put it into your flash. If you don't want to replace
your current bootloader, link redboot to run at a different block in
flash, and use your current bootloader to start it.

One thing to check with your current setup. Are the load addresses
different for redboot at the application? The application could be
over-writing redboot.
