my base board + orin(64GBVersion)，add 2 pcie2ethernet card
eth1:UPHY_TX0/RX0—>UPHY0 (C0@14180000), hsio-uphy-config-16
eth2:UPHY_TX7/RX7—>UPHY2 (C7@141e0000)，gbe-uphy-config-0
1.for design, modify p3701.conf.common:

 # Common values and/or defaults across P3701:

-ODMDATA="gbe-uphy-config-22,hsstp-lane-map-3,nvhs-uphy-config-0,hsio-uphy-config-0,gbe0-enable-10g";
+ODMDATA="gbe-uphy-config-0,hsstp-lane-map-3,nvhs-uphy-config-0,hsio-uphy-config-0";

2.dtb and kernel modify：

You told us you know which ODMDATA to set.
But when it really comes to bring it up, you didn’t set the ODMDATA as what you said… so what do you want here…??

l think ODMDATA value is Ok. But l don’t kown how to check ODMDATA by cat /sys/kernel/debug/bpmp/debug/uphy/config. Also pinmux is：

I have a qustion, I must need by Jetson_AGX_Orin_Series_Pinmux_Config_Template_1.9.xlsm generate diy xx.pinmux.dtsi/xx.gpio.dtsi or direct to change tegra234-mb1-bct-pinmux-p3701-0000-a04.dtsi and tegra234-mb1-bct-gpio-p3701-0000-a04.dtsi.

可能我用中文講比較清楚…

兩個錯誤

  1. 你一開始就提到C0要設定成 hsio-uphy-config-16

結果你設定根本就沒寫這個…

-ODMDATA=“gbe-uphy-config-22,hsstp-lane-map-3,nvhs-uphy-config-0,hsio-uphy-config-0,gbe0-enable-10g”;
+ODMDATA=“gbe-uphy-config-0,hsstp-lane-map-3,nvhs-uphy-config-0,hsio-uphy-config-0”;

  1. 為什麼你的 pcie@141e0000要寫<&p2u_gbe_5>? 你的hardware設計是如何？

谢谢！
1、C0设置已经改成 hsio-uphy-config-16：
#ODMDATA=“gbe-uphy-config-22,hsstp-lane-map-3,nvhs-uphy-config-0,hsio-uphy-config-0,gbe0-enable-10g”;
ODMDATA=“gbe-uphy-config-0,hsstp-lane-map-3,nvhs-uphy-config-0,hsio-uphy-config-16”;
2、板子设计使用的是UPHY Lane5，所以猜测应该是p2u_gbe_5。我还原回去

你的設計是沒辦法用的, 只有放在UPHY2, Lane 0或是UPHY2, Lane 7會動… C7是PCIe x8的設定…

C0可以检测到设备，C7有问题
