README
^^^^^

  This is the README file for the port of NuttX to the Arduino Mega 2560 Rev3.

    https://www.arduino.cc/en/Main/ArduinoBoardMega2560

  The board is based on ATMega2560 chip from Atmel

Toolchain
^^^^^^^^^

  Right now only Atmel's AVR8 Toolchain is supported. You can get it from

    http://www.atmel.com/tools/atmelavrtoolchainforwindows.aspx

  It is basically WinAVR compatible so sub-projects may define WinAVR as a
  tool-chain but specify path to the Atmel AVR8 in path. See
  arduino-mega2560/hello for example.
