DS160PT801: AER Issue of PCIe interface

Part Number: DS160PT801

Hi, I'm Minkyu Cho.

I have a question for debugging AER issue.

Current configuration is as below.

Root Complex (CPU) <-> PCIe Connector <-> Retimer <-> PCIe Connector <-> End Point.

But There are Corectable errors on CPU and Endpoint both side.

Currently, Retimer is using adaptive mode.

What should I do for resolving thie issue ?

Thank you.
