I've created a hardware bsp project using Xilinx SDK 14.1, and used the xilinx-ml507-update project, (after updating it to XPS 14.1 format).

Now the script in meta-xilinx/classes/xilinx-kernel.bbclass is looking for a *.dts file, but I don't see that being created anywhere, in my bsp projects.

The XPS SDK project is generated into the following location from your XPS system.mhs project:

/project/xilinx-sdk-workspace (which contains two subfolders linux_2_6_bsp_0, and xilinx-ml507_hw_platform)

Your XPS project is located in

/project/xilinx-ml507-updated

and my local.conf settings are 

XILINX_BSP_PATH ?= "/project/xilinx-ml507-updated"

is that the correct BSP path location? 

When I try to build the linux-xilinx recipe, I get the following errors:
