Is it possible to do DMA transferts with the IP core «Cyclone V Avalon-MM for PCIe» provided by altera in Qsys (quartus 14.0) ?
Altera provide an ip-core named «Cyclone V Avalon-MM DMA for PCIe» to do dma transfert. But this ip-core does not support PCIe Gen1 with 1x lane.
The demo (ep_g1x1) design for «Cyclone V Avalon-MM for PCIe» include a DMA block that is connected on Avalon-mm TX bus of PCIe ip-core.
Then I'm wondering if it's possible to write data from this DMA block to the root-complex (host) ? Because I can't find how to do that.
