TX1 using R28.1, and PCIE Can't be recognized using lspci (nothing is shown)

Robotics & Edge Computing Jetson & Embedded Systems Jetson TX1
1

I have tried several methods to recognize PCIE controller and device, but when I using lspci there’s nothing shown, and dmesg log always get “tegra-pcie 1003000.pcie-controller: PCIE: no end points detected”.
Can anyone give me some suggestion?

  1. HW design is : (USB Lane Mapping Configuration #4)
    PCIe#1_0 (Lane0) — Realtek Ethernet R8111 TX1 Pin(H41/H42+E41/E42)
    PCIe#0_0 (Lane4) — PCIe-to-USB FL1100 TX1 Pin(C40/C41+E40/E41)

  2. #lspci (Nothing is shown)

  3. DTS configuration (hardware/nvidia/platform/t210/jetson/kernel-dts/tegra210-jetson-cv-base-p2597-2180-a00.dts )

Dear Guys,

It’s a hardware problem, I have fixed. No need to focus.
