is it broken?

[monotask]

Hi all,

I bought a iMX233-OLinuXino-MINI-WiFi few weeks ago.
When I try to connect to it using the serial-cable-f the only things I can read are these codes:

0x80502008
          0x8020a014

one pair about every 20 secs.
If I insert the SD card with Olinuxino image codes change in:

0x80502008
          0x8020a01d

No output from the video.

Can I try something or I have to consider it broken?

your SD card have no valid image or your power supply is weak
