Hello, Nvidia community. We developed custom carrier board for AGX Xavier and want to connect two Xaviers via PCIe. We used C4 controller (UPHY 8 & 9, PEX_CLK4, PEX_C4_CLKREQ, PEX_C4_RST) for that purpose. However we have an issue on how to enable endpoint mode for C4 of one of Xaviers using ODMDAT…

Hi, PCIe controller can work in either root port or endpoint, we shouldn’t enable both nodes at the same time. For configuring PCIe C4 as endpoint add following settings. DT pcie_ep@14160000 { status = "okay"; phys = <&p2u_8>, <&p2u_9>; phy-names = "pcie-p2u-0", "pcie-p2u-1"; nvidia,pe…
