Hello
I received my board Orange Pi 2 weeks ago
try booting with lubuntu and bananian. Prepare 2 SD cards
one 8Gb / class 4
one 16Gb /class 10
these 2 SD cards were used before on Raspberry Pi.
Also try to format with SD format or reset card with dd
Transfer of the img were made with win32DidkImager and dd
With all these cards/systems/format combinations I never go to the complete boot !
I got 2 tux on the top of the screen but the boot sequence stops at the line :
waiting for root device /dev/mmcblk0p2
When removing/putting the usb plug of my usb hub I got some lines saying "oh ! no more keyboard and mouse"
or "oh ! keyboard and mouse are here again..." and NUM LOCK and SHIFT LOOCK work on the keyboard
So some parts work but it could never mount mmcblk0p2

This afternoon I try Igor Pecovnick raw file. http://www.igorpecovnik.com/2015/01/18/orange-pi-debian-sd-image/
it's a Debian Wheezy for Orange Pi
The card is a brand new one : Samsung 16Go class 6
The raw file was writen on the SD card with imagewriter
When booting I got the same thing (a screen ful of messages) but now the last message is
waiting for root device /dev/mmcblk0p1
usb keyboard in/out always send mesages when plug/unplug
Has anyone an idea about this? Can it be a hardware failure or something I made the wrong way ?
best regards

Hi framboise314,
Have you tried to use a USB key to start? I havn't tried yet but I know the button behind VGA interface is used to start the Orange with USB
Maybe it can work with an USB 2.0 key

I made few test boots and I had zero problems. Huh. My system uses only one partition so the output (waiting for root device /dev/mmcblk0p1) is correct. Kernel loads O.K. otherwise you won't get this far.

Than no idea I would suggest trying another / different SD card. If you are using imagewritter, close the program and unmount SD card reader from your host PC safely. Not just unplug the card when writting reaches 100% ...

There is also a (very) small possibility of hardware failure on the board side.
