# Like -c dryrun the -c dryboot programmer only emulates programming,
# albeit for communicating to bootloaders, ie, without a physical
# programmer between the host and the target AVR part. AVRDUDE behaves
# slightly different when talking to a bootloader: Whilst for most classic
# parts the flash memory looks like NOR-memory, ie, cleared bits cannot be
# set and therefore programming requires a chip erase first, bootloaders
# do have the power of erasing a flash page (setting it to all 0xff)
# before writing a page. This requires AVRDUDE to behave differently when
# talking to a bootloader, which it recognises by the prog_modes = PM_SPM
# setting below. -c dryboot allows exploring these differences at an
# emulation level.
