Example design: Agilex I-series devkit not detected by lspci (stuck in S_CFG_LINKWD_START)

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 @Wincent_Altera,

  • I added the smartVID to your project and it programs successfully now.
  • I tried 3 different motherboards (up to Gen3x16) and no one detects the card with the 22.1 project and your project.
  • I checked several times the physical connection, no issues, it's fully in and it works with all the other PCIe cards we have. Nevertheless, I could only test in lab servers where the card is vertically plugged in due to the PCIe bracket being 1cm taller than the standard size.

 

Thank you for the patch, I installed it and the project is compiling.

Regards,
