Trouble booting linux on SocKit development board

We just got the SoCKit development board and I'm trying to get the factory provided Linux image to boot. I've written the image to a micro-SD card, set the BOOTSel and FPGA configuration mode switches as directed.When I power on the board I can see Uboot but it can find the kernel. I get the following messages: "** Unable to use mmc 0:1 for fatload **" and then "Wrong Image Format for bootm command" and "ERROR: can't get kernel image!". Any idea's what's going on.
