Ah.... That's explained that. I just needed a nudge in the right direction.Now, why does the answer to one question lead to a whole bunch of suplimenty questions?Section? (blue highlighting)I can't find any reference in the Intel Hex File Format or the avr_objdump documentation.Is it a "compiler thing"? Writing to two sections of memory, which, in this case just happen to be contiguous?Many, (many), thanks for your patience, Martin
