title: Raspberry does not boot with android things
body: <p>Wrote Android things image on a micro SDCard and inserted that card into Raspberry Pi 3 Model B and turned on power,At starting it shows 'Auto config Please wait' then the screen remains empty</p>
  
  <p>I had tried connecting it with PC and it is not detected by adb</p>
  
  <p>How could we test whether it is booting OS or not?
  Why nothing is shown on the screen?</p>
