The biggest difference between these two devices is that the P30
always powers up with all blocks locked (the locks on the J3
retained their setting over power cycles/reset). This means
that you'll need to run 'fis unlock' commands(*) any time you
want RedBoot to write to the device.
(*) or the equivalent operation in an eCos program if you
are running FLASH-aware eCos applications.
