    Hi Sir,

    ​

    We did a lot of experiments, e.g. to reduce the required BAR space, to rule out BIOS issues, motherboard issues, and Linux OS issues.

    Yesterday we find a reference design from Terasic, that design uses "PCIe hard IP hen3x8", and it works on our platform.

    But the reference design is only PCIe and on-chip SRAM.

    We still need a whole system like AN881 with HBM2.

    ​

    Therefore, we strongly doubt that the root cause is some bugs in PCIe hard IP+ gen3x16 (Quartus V19.3).

    Please help to forward the information to design author, and fix the issue of AN881 reference design.

    ​

    Thanks.​

      Hi,

      ​

      Yes, we are trying.

      I'll reply to you after the experiment done.
