# Makefile for ATmegaBOOT
# E.Lins, 18.7.2005
# $Id$
#
# Instructions
#
# To make bootloader .hex file:
# make diecimila
# make lilypad
# make ng
# etc...
#
# To burn bootloader .hex file:
# make diecimila_isp
# make lilypad_isp
# make ng_isp
# etc...
#
# Edit History
# 201406xx: WestfW: More Makefile restructuring.
# Split off Makefile.1284, Makefile.extras, Makefile.custom
# So that in theory, the main Makefile contains only the
# official platforms, and does not need to be modified to
# add "less supported" chips and boards.
# 201303xx: WestfW: Major Makefile restructuring.
# Allows options on Make command line "make xx LED=B3"
# (see also pin_defs.h)
# Divide into "chip" targets and "board" targets.
# Most boards are (recursive) board targets with options.
# Move isp target to separate makefile (fixes m8 EFUSE)
# Some (many) targets will now be rebuilt when not
# strictly necessary, so that options will be included.
# (any "make" with options will always compile.)
# Set many variables with ?= so they can be overridden
# Use arduinoISP settings as default for ISP targets
#
#----------------------------------------------------------------------

# "Chip-level Platform" targets.
# A "Chip-level Platform" compiles for a particular chip, but probably does
# not have "standard" values for things like clock speed, LED pin, etc.
# Makes for chip-level platforms should usually explicitly define their
# options like: "make atmega1285 AVR_FREQ=16000000L LED=D0"
#---------------------------------------------------------------------------
#
# Note about fuses:
# the efuse should really be 0xf8; since, however, only the lower
# three bits of that byte are used on the atmega168, avrdude gets
# confused if you specify 1's for the higher bits, see:
# http://tinker.it/now/2007/02/24/the-tale-of-avrdude-atmega168-and-extended-bits-fuses/
#
# similarly, the lock bits should be 0xff instead of 0x3f (to
# unlock the bootloader section) and 0xcf instead of 0x2f (to
# lock it), but since the high two bits of the lock byte are
# unused, avrdude would get confused.
