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,


Initially, I suspend R-Tile's different behavior on different Motherboard may be related to Preset negotiation between Motherboard and R-Tile.

Is okay, let see the result after you compile the file.


Looking forward to hear back from you.

It compiled successfully but the Programmer fails at 5%:

Error(18950): Device has stopped receiving configuration data
Error(18948): Error message received from device: External hardware access error. (Subcode 0x0032, Info 0x00040008, Location 0x00001800)
Error(22248): Detected a PMBUS error during configuration. Potential errors: VID setting is incorrect in the Intel Quartus Prime project. The target device fails to communicate to a smart regulator or PMBUS master on a board.
Error(209012): Operation failed

Just in case, I attached the archive of the example design (2. in my question) generated with 22.1.
