# Hey Emacs, this is a -*- makefile -*- |
# |
# Makefile for the AVRProg-compatible Bootloader |
# |
# based on the |
# WinAVR Sample makefile written by Eric B. Weddington, Jörg Wunsch, et al. |
# Released to the Public Domain |
# Please read the make user manual! |
# |
# Additional material for this makefile was submitted by: |
# Tim Henigan |
# Peter Fleury |
# Reiner Patommel |
# Sander Pool |
# Frederik Rouleau |
# Markus Pfaff |
# |
# On command line: |
# |
# make all = Make software. |
# |
# make clean = Clean out built project files. |
# |
# make coff = Convert ELF to AVR COFF (for use with AVR Studio 3.x or VMLAB). |
# |
# make extcoff = Convert ELF to AVR Extended COFF (for use with AVR Studio |
# 4.07 or greater). |
# |
# make program = Download the hex file to the device, using avrdude. Please |
# customize the avrdude settings below first! |
# |
# make filename.s = Just compile filename.c into the assembler code only |
# |
# To rebuild project do "make clean" then "make all". |

# MCU name |
