This bl updater can be flashed as app and will update the bootloader and then delete itself before resetting the sam3, so the device will end up in the newly updated dfu bootloader afterwards, without having to press the bootloader button or requring any other manual interaction, ready to receive a new application image. Building the blupdater requires a previously built dfu-flash bootloader bin file that will then be embedded into the app during building.
