PCIe Driver Issue for Windows 10

Hi, I've read questions about this topic but I couldn't find an answer.

1)    I am trying to use Xilinx DMA Subsystem for PCIe IP core. In order to do this, I tried to work with driver of this module. "Xilinx PCI Express DMA Drivers and Software Guide" document declares that only "Windows 7 Enterprise 64-bit" is supported. However there is a version for Windows 10 Driver in the files, so I am confused. Can I use the driver with Windows 10 or is it impossible? By the way, when I plug the module on PC, I see nothing on my device manager about PCIe (Document claims that I should see a PCI Memory Controller Device). I have marked some parts of the document. Pictures are attached to the question.

 

2) In order to understand the principles of  IP core, I used the example design. But when I try to generate bitstream file, it failed. Error is about "sys_rst_n". Error message says that "sys_rst_n" is not assigned to a I/O in constraint file. So, I've checked the constraint file and saw that sys_rst_n is assigned as "set_property PULLUP true". Does anyone knows why the example design of the IP core cannot be generated?

 

Thanks in advance.

Re: PCIe Driver Issue for Windows 10

I found the reason of the issue. In order to work with PCI, IP core must be activated in FPGA via bitstream. I relized that the example design was not created for Kintex 7 (I think it was created for Virtex 7). So, I have solved it with a different bit file. Now I can see that my device manager detects PCI Memory Controller. However, when I try to follow the steps of the document AR# 65444 (which I have attached at the post above), Windows gives me an eror. I have attached this error. The problem is, there is no document for Windows 10 at Xilinx.com. So I doubt if I follow the right procedure..3.PNG
