The bigest problem is that there are only 24 hours in a day, and of those 24
hours, I only spend 8 hours working, and of those 8 hours, I spend 2-4 in
#!%$# meetings ;-)

Seriously, I haven't had any problems.  I just haven't spent any time at all
trying to look at it.  I have heard that there is a non-standard, vendor
specific, register related to the MMU, but since I have never studied the
ARM MMU before, I probably won't recognized what is standard and what is not
as I read through the TI documentation.  I expect that if I just turn the
crank long enough, things will work.

In the mean time, since RedBoot doesn't need interrupts, and only needs the
exception vectors if I want to use GDB stubs, I ignored the issue for now
and created a RedBoot that runs from (internal) RAM, that loads and runs a
"Hello World" program from FLASH, and which impressed a potential customer
with just a week's worth of work.

Again, thank you!
