So long as you can access the flash early in the bootblock, then that can work. Reading the FMAP is not trivial and takes a small amount of time.

We discussed making a 'fixed offset' in the flash an option.

I would like to move forward with this...can someone perhaps persuade Julius to remove the -2 ?
