Cannot load PCIe driver into the linux of Atom, De2i-150

I followed everything that the manual said to build a PCIe system using Qsys, where user logic has nothing else but a LED I/O.

I generated the Qsys and loaded the *.sof file onto the board, and rebooted the yocto system.

now here comes the problem, I tried to install the PCI driver that Terasic provided but the ternimal kept telling me "Matching device not found", it's strange that I did set the right vender number and system number in the config file corresponding to my Qsys design. I even tried just copy the whole Qsys PCI design that the demo given into my own project but same error happens.

I can only install the driver when I use the *.sof file of the demo. I need to build my only PCI system to meet my needs.

Please help me or give me some hints, thanks, that would be greatly appreciated.

    I'm having the same error message.

    Following demo instructions..

    After configuring FPGA board, in Yocto host: "sh ./load_terasic_qsys_pcie_driver.sh de2i_150_config_file"

    error: "Matching Device Not Found"

    de2i_150_config_file:

    vendor id - 0x1172

    device id - 0xe001

    These ids were verified from the FPGA source files.

    The PCIe driver was loaded successfully, terasic_qsys_pcie.ko. The FPGA is working A okay as well.

    However, Yocto cannot see the FPGA as a PCI device.

    Will be very thankful for any help on this.
