Enabling Tandem PROM in the PCI EP core configuration menu

Hello,

 

I have a fully functioning and working FPGA design on a Kintex 7 part that involves a DMA/Bridge Subsystem core for PCI-e. I faced issues with the device enumerating and so I am in the process of recreating a tandem PROM bit stream. However, when I try to reconfigure the PCIe EP core (inside the DMA hierarchy) the Tandem Prom checkbox is always greyed out. It is also greyed out if I try to generate a brand new PCIe EP. 

 

What is the cause of this?

PG195 mentions the following under "Unsupported Features".

Tandem Configuration solutions (Tandem PROM, Tandem PCIe, Tandem with Field Updates, PR over PCIe) are not supported for Virtex®-7 XT and 7 series Gen 2 devices.

Kintex-7 comes under 7 series Gen 2 devices.
