This looks a bit odd -- I'm pretty sure the hardware doesn't
get only the reset address from an IMPDEF location.
Are you sure this board doesn't actually have an IMPDEF
reset value for the vector table offset register VTOR?

Which CPU core is this, anyway? Googling suggests
it's a Cortex-M4, and the M4 TRM suggests that VTOR
always resets to 0.
