Arria II GX PCIe card not recognized by OS

Hi, all

I purchased the Arria II GX development kit and happily place it on my server's PCI slot, without changing any DIP switch or anything. But after OS (linux) boots, I can't find the device with lspci. Are there any special operation needed? Does the factory image includes the PCIe support?

Sorry if this is an naive question. I searched around for a long time and get no answer. Any input will be helpful.

Thanks

    Alex, thanks for replying.

    So do you have any hints how should I setup the SW3? I plugged the card into a X4 slot (in a riser card). I tried turn off Switch 2, i.e. connecting PCIE_PRSNT2n_x4 to PRSNT1, but no difference. I also noticed none of D24/D25/D26 is on, which, according to the reference manual table 2-11, (https://www.altera.com/en_us/pdfs/literature/manual/rm_aiigx_fpga_dev_board.pdf ), are the PCIe link width.

    Just curios that if the factory image includes PCI functionality or not.

    Thanks

    Some update:

    I change the SW3, turn off switch 1(i.e. connecting PCIE_PRSNT2n_x1 to PRSNT1) although it's in a x4 slot. And also I compiled the PCIe_hiperf_a2gx and programmed it to the card, in the end, my system can recognize the device. It does not always work, but at least works several time for me.
