title: tinkerboard android - /sys/class/thermal/thermal_zone1/temp: No such file or directory
body: <p>I am using a tinkerboard with an android + chroot linux. When I try to read temperature by the following command:</p>
  
  <pre><code>cat  /sys/class/thermal/thermal_zone1/temp
  </code></pre>
  
  <p>I get the following error :</p>
  
  <pre><code>cat: /sys/class/thermal/thermal_zone1/temp: No such file or directory
  </code></pre>
  
  <p>If I run the tinkerboard directly with a linux distribution rather than android I am able to read the temperature by the above command. </p>
  
  <p>The tinkerboard uses the RK3288 cpu which has a TS-ADC <a href="http://www.boardcon.com/download/Rockchip-RK3288-datasheet-V1.0.pdf" rel="nofollow noreferrer">temperature sensor.</a></p>
  
  <p>Any suggestions?</p>
