  <p>It does not appear to have built anything, but rather is asking me which board and tool chain I wish to use.  </p>
  
  <p>My goal is to compile <a href="https://github.com/openwsn-berkeley/openwsn-fw/tree/develop/firmware/openos/bsp/chips/at86rf231" rel="nofollow">https://github.com/openwsn-berkeley/openwsn-fw/tree/develop/firmware/openos/bsp/chips/at86rf231</a></p>
  
  <p>What is the easiest way to get the code for an AT86RF231 compiled? </p>
