What amazes me here, considering all the replies to the OP I see here
so far, is nobody has mentioned one of the most important reasons for
having boot code.

How do you do a complete memory test before calling the C start-up
code that requires at least some memory be working? How do you test
the watchdog chip by forcing a reset?

Don't any of you do serious POST testing of your hardware?
