title: Buildroot - cubieboard 2 not booting
body: <p>I just borrowed cubieboard2 from my friend and tried to boot it up.
  I connected power to 2A USB charger, hdmi to my display and keyboard to USB.
  Red (Power) light turned on.</p>
  
  <p><strong>Whithout SD card</strong> system boots from NAND, kernel messages shows up, but hangs on</p>
  
  <pre><code>[     17.000000] Mali display drivers loaded (SOMETHING LIKE THAT)
  </code></pre>
  
  <p>Nothing more is happening, but system is responding, because when I insert SD card it shows propper mesage:</p>
  
  <pre><code>[    800.000000] sd card info...
  </code></pre>
  
  <p>The default system on NAND should be android (my friend didnt touch it), but I'm not able to get anything more then kernel log</p>
  
  <p><strong>With lubuntu SD card</strong> system boots up properly, but the first image I get is desktop. After power on - screen turns on, but is whole black, no messages at all. After about 3 minutes desktop shows up.</p>
  
  <p><strong>With default cubieboard2 busybox</strong> created exactly as on <a href="http://www.smida.it/geekeries/cubieboard-buildroot.php" rel="nofollow">http://www.smida.it/geekeries/cubieboard-buildroot.php</a> - this is the most frustrating part! It took about 5 hours to make image using virtual gentoo machine on my pc. After that i created SD card with my OS. When I inserted SD card and booted device - screen turns on, there is some SD card activity, but no image at all. Screen is black (but turned on), SD activity LED blinks for a moment and then... nothing. Num-lock responds, pressing random keys - no SD card activity, but alt-ctr-del gives board a restart.</p>
  
  <ul>
  <li>How can I make my board working?</li>
  <li>Is there any way to 'debug' it? By connecting serial interface or something like that?</li>
  <li>Can I 'emulate' image on my gentoo virtual machine using qemu?</li>
  <li>Maybe there is obvious mistake I'm doing?</li>
  </ul>
