My udoo x86 has been working great since I got it 2-3 weeks ago. It was working fine this morning. Now it won't boot. I plug in the power jack and the yellow status light comes on. But nothing happens on my monitor. I've been using this thing to develop an android app the last couple of weeks and haven't backed any code up in like a week so I'd really like to figure out how to get this thing working again. What does the yellow status light mean? In the documentation I can't find anything on that. And is there any button I can try to press on the board? I don't have a level shifter so I can't use the UART, and I only have 1 power supply and no way to test it. It was like 10$ on amazon and I'm worried it may have gone bad and isn't putting out enough power. Which would probably be the best case for me.
