Hi, I'm working with kc705 trd project. I'm working now in UBUNTU 14. I'm using pci_x8_gen1.mcs and i see device "Memory Controller : Xilinx corporation Device 7081" after command "lspci". I changed PCI_DEVICE_ID_DMA to 0x7081 in xdma_base.c file. I make linux driver, but in list (after command 'lsmod') i see only "xdma_k7 0" . XRAWDATA0 and XRAWDATA1 is not make and not working. I want to understand how to read/write the data from/to kc705 board throw PCIe.

For Example write data to the file.
