I've modified the AC701 project to work with another Artix-7 board. This board does not have any memory external to the FPGA and I get errors about the design not having any RAMBs. I removed components that the board doesn't have, ethernet, DDR3 MIG, and HDMI. Do the reference designs require external memory to function properly? Can the FPGA's block RAMS suffice? Thank you.
I'm using Vivado 2014.2 and I am able to synthesize the normal AC701 project.
