This board isn't available in the list of boardas I have in either 2017.4 4 or 2018.3. If that's the case where do I find the board file? Please be more specific than they can be found at https://www.xilinx.com/products/boards-and-kits/ek-u1-zcu102-g.html#documentation. I have looked at this link and I've not found them.
The ZCU 102 es2 should be available for Vivado 2017.1. When you are selecting the board or part for the ZCU, you can select the all the board revs (see the attached image)
Let me know if this helps
