freedom: how to build VCU118 FPGA with edge_xdma from fmc_xdma settings? #108

Currently, we have successfully built VCU118 FPGA with PCIe RC mode (fmc_xdma). Now we are switching to PCIe Endpoint mode (edge_xdma), however with no success. What is the best way to build VCU118 with PCIe in Endpoint mode? Thanks

Hi @shawnofthedead

The edge_xdma that you see here https://github.com/sifive/fpga-shells/blob/9eb56625ba252e6abbb7ded5158331b7da7ea39a/src/main/scala/shell/xilinx/VCU118NewShell.scala#L230 is intended to provide PCIe Root Complex operation using the VCU118 PCIe finger connection + one of these : https://www.xilinx.com/products/boards-and-kits/1-fd4b4j.html Currently there is no support for endpoint mode.
