All the bootloaders I've worked with or written have though I haven't
worked with a boot loader in a while. I'm a network engineer, not an
embedded engineer anymore. Now this is my 'hobby'.

Ah, I think you've hit it on the head. Though I would have expected
the hardware engineer to have some 'common sense'. Is it not normal
for a hardware engineer to know some software? Or am I expecting
too much? Don't hardware engineers work with software engineer or
is everything just thrown over the wall to the next team?
