Bootloader for Arduino Mega2560

In order to use the Mega2560 from Emartee in China, you need to make these changes to the Arduino environment. You will also need an ISP programmer

• In the folder hardware -> arduino is a filed called "boards.txt"
  On the Mac, this is Applications -> Arduino.app -> Contents -> Resources -> Java -> hardware
  Add the boards section below to the end of "boards.txt"

• Place the ATmegaBOOT_168_mega2560.hex.zip file in this folder (unzip it of course)
  Applications -> Arduino.app -> Contents -> Resources -> Java -> hardware -> arduino -> bootloaders -> atmega

• Replace the core files with this file arduino.zip
  First you should rename the old one to ardino.old, the path is Applications -> Arduino.app -> Contents -> Resources -> Java -> hardware -> arduino -> cores -> arduino

• Re-start the Arduino application

• From the Tools -> Board menu select "Arduino Mega2560"

• Connect your ISP programmer to the Mega2560 board

• From the Tools -> Burn Bootloader menu select the appropriate ISP programmer

• When you do the burn, most likely you will get the following error, you can igore it

  		avrdude: verification error, first mismatch at byte 0x3e000
  		         0x0d != 0xff
  		avrdude: verification error; content mismatch
  		

• Now you should be able to use the Mega2560 just like any other Arduino board.

add this to boards.txt
