    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
