Jetpack 5.1.2 PCIe C4 failed to detect I210

[4nila97]

Hi,

I can detect I210 ethernet controller in Jetpack 4.6.0, but failed in Jetpack 5.1.2.
I use lspci command failed to get I210 ethernet controller.

I have modified my dts as below

Our custom board I210 is connected to UPHY_TX8

Do i need to change ODMDATA value to enable PCIe C4?

Please help. Thanks~

Could you share the dts file that converted back from dtb and attach here?

Could you use p2u-0 instead of pcie-p2u-0? Your version is TEGRA_PCIE_VERSION >= DT_VERSION_2 one. But not the old one.
