Well, is your program targeting that board? Does it (for instance)
link at an address corresponding to flash or RAM on those
boards? Does it have the exception vector table at address zero
which a real ROM image would have? Does whatever C library
you're linking against make assumptions about RAM size or
location?
"Sits at 0x0" usually means "guest code did something wrong
and we're in an infinite loop of exceptions because the guest
image doesn't have any exception vector table in place either".
