How to resolve "Specified kernel was not built for any devices"

OpenVINO come with pre-compiled FPGA bitstreams and only supports two of Intel's own Arria 10 boards as mentioned in the link below. You cannot use it on any other boards, including your Bittware board.

If you just want to use OpenCL, then you do not need to use the OpenVINO docker image since it is specifically made to target the supported boards mentioned above. You just need to get the OpenCL BSP for your board from Bitware's portal and set up your environment as described here:

You can then compile and run OpenCL kernels for your board.
