AM5728: PCIe RC plus EP configuration

Raman Mistry

Part Number: AM5728

Hi,

Looking to use the PCIe in AM5728 as 2 separate x1 lanes. Require 1 lane to be RC and the other as EP. Is it possible to run them at different rates EP would be 5Gbps and RC would be 2.5Gbps

Hi, Raman,

There are 2 PCIe controllers on AM5728 SoC. One can be configured as RC and the other EP. The rate will be auto-negotiated during enumeration.
