title: Location of boards.txt for an Arduino DUE (SAM board)
body: <p>I use the 1.6.7 Arduino IDE and I’ve installed the <em>"Arduino SAM Boards (32-bits ARM Cortex-M3)"</em> item for my DUE board, and it works fine. </p>
  
  <p>However, I would like to tune some build parameters in my <code>boards.txt</code> file. <strong>Problem</strong>: I do not have a <code>INSTALL/hardware/arduino/sam</code> folder!
  I do have the traditional <code>INSTALL/hardware/arduino/avr</code> folder, but in this one <code>boards.txt</code> does not contain the settings for the DUE.</p>
  
  <ul>
  <li>Where can the settings of the DUE be found? </li>
  <li>Should I create myself a new <code>boards.txt</code> file in a new <code>sam/</code> folder? What should be its default content?</li>
  </ul>
