title: Using SD card as external storage in Beaglebone Black Debian 8.7
body: <p>I had been working a while with my BBB and decided to update to last image, so I followed the guide on the Beagleboard.org site, I succeeded and now have the Debian 8.7 2017-03-19 image working just fine. However, before the update I had that same SD card as extra storage and now every time I put it into the BBB it flashes, so I would like to have that same SD card as extra storage as before.</p>
  
  <p>Doing some research I read it was needed to have a uEnv.txt file with the following lines in the SD card:</p>
  
  <pre><code>mmcdev=1
  bootpart=1:2  
  mmcroot=/dev/mmcblk1p2 ro  
  optargs=quiet 
  </code></pre>
  
  <p>I'm newbie at this so I don't really know how to do so and the information I have found is not that explanatory. I would really aprecciate some help in doing this so I can start making more interesting applications. Thanks.</p>
