title: Not able to upload code on CC2538dk board from Ubuntu 12.04 command line
body: <p>I have a CC2538dk board. I am using Ubuntu 12.04 and cloned <a href="https://github.com/contiki-os/contiki/" rel="nofollow">Contiki repository</a> from github. I was able to compile all the code in Contiki using <code>make TARGET=cc2538dk hello-world</code>, but I'm not able to upload the code to the CC2538dk board from command line.</p>
  
  <p>The error I'm getting when I ran <code>make TARGET=cc2538dk hello-world.upload</code> is as below.</p>
  
  <pre class="lang-none prettyprint-override"><code>make: No rule to make target `hello-world.upload'.  Stop.
  </code></pre>
  
  <p>I used to use TI's Uniflash tool (CCS_Uniflash v2.2) to upload the the <code>.elf</code> binary, but it is not available in Contiki.</p>
