There are two more things I am not clear with.

1. Why must code and images match? If FPGA image is newer than the UHD code one have installed, according to my logic only things that are different would not work.
 
2. I want to adjust the FPGA image slightly.  I want to write some extra Verilog code and build it myself with Xilinx. However, since I change the image on the FPGA, and the installed UHD code has to match to the image, how can this work?

Thank you in advance.
