RTOS/XIO2001: XIO2001 support ASPM function fail

Part Number: XIO2001

Tool/software: TI-RTOS

Hi Sir

Our question as below.

Testing conditions : PCI bridge XIO2001 connect with Intel PCH B365(Schematics as below)

If we need support ASPM function, the bridge will hang, not work normaly.

Disable ASPM function, it can work normaly.

Could you share maybe which one behavior cause it? Thanks for your great support.
