How to expand the PCIe interface on AM335x [Copy link]

  AM335x itself does not have a PCIe interface. I have never done a similar design before. I would like to ask how to use AM335x to expand 2-way PCIe interface! That is, use AM335x to make a Linux system, and then add PCIe function to the system, so that some functions can be expanded! In this case, a PCIe chip needs to be added. Which one should be added, the PCIe switch chip or the bridge chip? It is not very clear from the search, please ask everyone for advice! Thank you very much!

What is the use of adding PCI-E to the system?

It is mainly used for external expansion cards! There are two uses, one is to expand some interfaces, and the other is to expand an interface for display!

I have used both 335x and PCIE. I am curious about your thoughts.
