makefile

一款MP3 Player Firmware 的原代码,非常有参考价值

# there are four builds... mp3player.hex has everything and it is the
# one that must be distributed to end users.  The other three include
# less stuff, which allows developers to have quick download times.
# Developers only coding in C should download "main.hex" (after erasing
# with 'X').  Developers also working on drivers should use "devmain.hex"
# (after erasing with 'Y').
