I'm using xdma core in ultrascale+ project. Question is how can I extend window in BARs? I need to extend them to 64 GB window. And I have an issue while writing and reading data frames from PC to board using xdma core via PCIe bus. PCIe driver hangs if size of frame is bigger than 4KB. Why does that happens? In my previius projects with Virtex 7 it was ok with frames bigher than 4KB.
