Got it about a week ago (finally) and was super excited to use it, when I set it up and plugged it in it did not boot at all, nothing on the video. What's your plan to fix this DOA device for me?
I'm trying with another image on a different usb stick, if it still doesn't work I'd like to know what the process is to get it replaced with a working one or how to get my money back.
rcuser: I think you're going to have to post a bunch of additional information before anyone can know what the cause of your failure-to-boot is. Initial troubleshooting of this sort of embedded board generally requires low-level interaction with the boot code, and that will require hooking up a USB-to-serial debug adapter (see the "booting non-headless" thread).
There are many possible culprits... bad LaFrite board, bad or incompatible USB stick(s), bad power supply, bad downloaded image, bad flashing, wrong port, interference from another USB peripheral... etc. Without knowing more about your test setup, and without seeing the serial output if any from u-boot, I don't think anyone can really tell whether your board is bad or not.
First time I powered the board I had connected a HDMI monitor to it, but no USB, no keyboard or serial.
After applying power I seem to recall both the red and green light on the board lighted up and the board started to emit uboot messages to the display.
If no led lights up, I'd suggest checking your power supply. I used a 2A one. And make sure it is connected properly.
Guess you should not use a USB cable to connect the board to your computer and rely on your computer powering it as computer ports may be limited to 500 mA. Not sure if that is enough.
Thanks for the feedback Frans. 1) Does the LED on the board light up? Yes 2) Does your monitor light up with a logo in the center? No 3) If not, have you tried another monitor? Yes, and different power sources, hdmi cables, and keyboards

Hmm. I just checked, My PSU is 5V 3A but that is maybe overkill.
If I power the board (nothing connected) the red and green light immediately start to glow.
After about 5 seconds the screen shows a large L in the center and some u-boot logging in the lower left corner.
I didn't check resolution (sorry), but it could be there is a mismatch between board and monitor.
You also could try a serial cable (I didn't do that yet, still on my todo list). These are not very expensive if you order on ebay
(and make sure to order something that has drivers for your os).
Good luck! Frans
PS: you could also take the gamble and write the debian headless image to a usb stick and see if it boots. Maybe the display will show something as it might handle the video differently from u-boot. Also if you connect a network cable you might see a DHCP request on your router; if you see an address in the router you might be able to ssh into it (user: libre, password: computer)
When buying a USB-to-serial debug cable, make sure it's one that uses 3.3-volt signaling! If you get a cable designed for 5-volt serial signals (like a lot of older designs) it might damage the LaFrite. I don't know for certain about the 805X processor, but the earlier 805 processor's data sheet says that its I/O pins are designed for 1.8 or 3.3 volt operation. I don't think they're 5-volt-tolerant.
