Thanks for the info.

    Hello Rong,

    The reading of the address 10h (BAR0) in the Agilex 7 PCIe RP is equal to 00h.

    Can you check this write access :

    It is supposed to be a Memory Write at address 40000014h of 1DW with the value 00460000h

    The Completion is an Error Message IRQ code 31h :

    Thank you.
    Serge
