title: Programming SAM uC family without ATmel Studio
body: <p>I've asked this question on  :<a href="https://electronics.stackexchange.com/">https://electronics.stackexchange.com/</a> 
  with no success, So I'm trying my luck here.</p>
  
  <p>I've designed a board that used a SAM uC (Cortex M0+). I don't want to use the ATmel Stduio, I want to learn how to use eclipse and arm-gcc and OpenOCD ( still can't understand, what this one is for ?). So  my question is it possible to do that and if yes, does anyone has hint how can I proceed ? </p>
  
  <p>I've installed the 3 parts,and this is the farthest  I could get:
