Software support for PCIe connectivity will be made available in a future BSP release.

PCIe connectivity is accessible at the connector X20. The reference clock signals can be configured to sync with the clock generated externally by a PI6C557-03 PCI Express Clock generator at U1, or from the SERDES reference clock from the phyCORE-AM65x SOM. Reference the table below for the jumper settings available.
