I've been trying to compile a PCI Express example design for the Agilex I-series devkit. 1. Nothing works on the projects provided here ES (21.2 or higher) Found here: https://www.intel.com/cont...

    I found the issue.

    The default position for the SW3 is defined in the UG as OFF/ON/ON/OFF, to use the refclk from the connector.

    The board was received with OFF/OFF/OFF/OFF, to use the on-board refclk.

    I set the SW3 as documented and it's now enumerated by the bios and seen in lspci.

    Why it doesn't work using the on-board refclks?

    Devkit: DK-DEV-AGI027RES

    Serial number: AGIPCIE8000248

Hi,

Can you try the file at the attachment.
also, I suggest trying another Motherboard which is Gen4x16 capable.

Let me know if the problem fixes.

    Hi @Wincent_Altera,

    Thank you, it's currently compiling with Quartus Pro 21.2.

    At this moment, I don't have a Gen4x16 capable motherboard available, only Gen3x16.

    Regards,
