Hello.

The 3 A20-Olinuxino-Micro that I bought some time ago arrived today, I'm very happy about that.
I bought some VGA-connectors as well. Then I connected the VGA onto Olinuxino and to my Monitor.
I turn on Olinuxino and nothing happens, besides a black screen and a white cross that appears on the center of the screen.
Does anyone knows how to correctly connect VGA to Olinuxino?
I tried to connect a mouse and a keyboard to the Olinuxino but nothing works.
I also tried to use the script change_display....sh but none of the resolutions seems to work.

Thank you

I forgot to say that I use Debian Wheezy as OS and I access my Olinuxino via SSH/Ethernet.

Now I connected a mouse and a keyboard to the Olinuxino via USB.
Every 30 seconds I get this message:

I succeeded, but I don`t know what solved my problem. I changed the Olinuxino, the VGA cable and the Debian Image.
