- boot.c: basic boot loader that runs DFU for 2 s, then starts the payload - board.h (DFU_USB_VENDOR, DFU_USB_PRODUCT): added USB IDs for DFU - flash.c: stubs for board-specific Flash functions - Makefile: build boot.hex for the boot loader - Makefile (prog): load the boot loader at its rightful place - Makefile (prog): also set hfuse and the lock fuse
