Our host PC can't discover Stratix 10 MX devkit as a PCIe device, even after a successful configuration and a proper installation of Linux driver.

We are trying to use Intel's DMA IP and PCIe Hard IP+ to communicate to the HBM memory. So far, we've tested AN881 design, AVMM PCIe Hard IP+ example design, and the PCIe golden design that comes wit...

    Hi Hsuh,

    The initial post was mention about AN811 but now become AN881. So I just curious if you already tested the AN881.

    1. For the AN881 example design, it is using v19.1 pro. Did you run the Post-processing Script (section 2.2) if you re-generate the Platform designer or upgrade the design?
    2. Is your MX board consist of the following device? 1SM21BHU2F53E1VG
    3. Are you using the driver that comes with the AN881 example design?
    4. Do you have a chance to validate it on the CentOS 7.0 and see if there is any OS dependency?
    5. Could you please capture ltssmstate[5:0], currentspeed[1:0], lane_act[4:0] and link_up signal from Signaltap? This can help to confirm if the link training is up correctly.

    Regards -SK

Thank you for your answer.

I've been suffered quite a long time with this problem. Having help from Intel is grateful and I am glad to talk to you.

But you should read my post at least in some important points, like environmental info. That five lines of comment have information that someone might be interested in if he really wants to help.

I clearly stated that I have tested the AN881 example design. I followed instructions there and it is not working even after I followed instruction exactly as the manual described. We've also consulted "Avalon-MM Intel Stratix 10 Hard IP+ for PCI Express Solutions User Guide"(UG-20170) because it contains the necessary information to install a Linux driver for PCIe communication.

I know Intel's new "24 hour quick response policy" that kicked in recently, but please, read before you post anything.

Best, HSuh.
