Maybe, but I don't think so. At least I see no  code  in  ARMBoot  to
relocate the exception vectors.

Do you still have access to an ARMBoot based system using interrupts?
Do interrupts continue to work when you  are  running  from  RAM  and
erase the flash?

Of course there's no reason for it, it's just our policy.
