[chengcheng2015]

hi, we extended 3 netcard (microchip lan7430), one link to C1 UPHY_RX0/TX0 X1 mode, another link to C3 UPHY_RX3/TX3 X1 mode, third is link to C4 UPHY_RX8/TX8 X2 mode, add lan7430 origin drivers to kernel. Flash to Xavier industrial module on the my board, UPHY_RX0/TX0 and UPHY_RX3/TX3 netcard is ok, but C4 UPHY_RX8/TX8 netcard failed to identify. pls help check pcie UPHY config guide. tks

Hi, are you testing on devkit or custom board? Did you check the Design Guide for the possible lane mapping of PCIe? Please do that first and confirm your configuration does not violate the DG.

open pcie c4, is ok

C4 by default is not enabled because devkit does not use it. Please enable pcie controller 14160000 in your device tree first.
