# Hey Emacs, this is a -*- makefile -*-
#
#
# based on
# WinARM template makefile
# by Martin Thomas, Kaiserslautern, Germany
# <eversmith@heizung-thomas.de>
#
# based on the WinAVR makefile written by Eric B. Weddington, J?g Wunsch, et al.
# Released to the Public Domain
# Please read the make user manual!
#
#
# On command line:
#
# make all = Make software.
#
# make clean = Clean out built project files.
#
# To rebuild project do "make clean" then "make all".
#
# Requires:
# - CodeSourcery Toolchain (tested & working with Lite version under Windows & Linux)
# - startup912.s and startup_generic.s to be renamed to .S with capital "S" to avoid deletion when calling "make clean"
# - Changes in file: scripts/flash_str9.ld
#       replace:        ./obj/startup912.o (.text) /* Startup code */
#       to:             ./startup912.o (.text)  /* Startup code */
#       or else change it to where this file is relative to current dir.
