Did you resolve this issue. I see the same issue on this board. Based on some other threads i have tried to use dd command to copy the image myself, but the /dev/fpga0 partition is not loaded.

Check the MSEL switch at the botton of the board. 

If you are booting the LXDE linux flavor, you will need to ground all MSEM pins.  If you need the /dev/fpga0 to be present, you can actually boot LXDE with the other uImage, the one used in Yocto's flavor. This workaround is presented by ep1015 in this thread: http://www.alteraforum.com/forum/showthread.php?t=47258 That is what I need right now as I'm trying to run OpenCL on LXDE, but I could not manage xserver to work on it yet :(  regards
