How to correctly config TX2 PCIE USB？

[839893211]

Hi,DaneLLL,

Thank you for your advice.
My workplace is from Tegra186_Linux_R28.2.1_aarch64.tbz2 and Tegra_Linux_Sample-Root-Filesystem_R28.2.1_aarch64.tbz2,which downloaded by jetpack3.3.
I configure uphy to #3, My board has an rlt_nic (RTL8111F) attached to the pcie bus(PEX2,LANE3).
1、I modified ODMDATA=0x6090000(p2771-0000.conf.common).
2、I commented out fragment-500-pcie-config and fragment-500-e3325-pcie in tegra186-quill-p3310-1000-a00-plugin-manager.dtsi.
3、I modified tegra186-quill-p3310-1000-c03-00-base.dts according to Tegra_Linux_Driver_Package_TX2_Adaptation_Guide.pdf.

I didn’t modify pinmux,because the tegra186-mb1-bct-pad-quill-char-e3301-1080-a00.cfg and tegra186-quill-p3310-1000-a00-pinmux-gpio.cfg generated by latest Jetson-TX2-Series-Pinmux-Template.xlsm cause system crash. I do not why.

Now I can see the pci and eth1 devices.

$ ifconfig eth1
eth1 Link encap:Ethernet HWaddr 00:00:00:00:00:03
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
$ lspci
00:02.0 PCI bridge: NVIDIA Corporation Device 10e6 (rev a1)
01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 07)

But there is a strange question, the configuration of eth1 remains unchanged,the physical connection hasn’t changed,The only difference is the reset. if Power on reset by reset button ,tx2 can not ping PC,also PC can not ping TX2. if Software reset by cmd（sudo reboot），eth1 works well,Tx2 and PC can ping each other.

Why does this happen?

Also i copy firmware rtl_nic in rootfs（Jetpack4.2.2 R32.2.1） to jetpak3.3 R28.2.1 rootfs.

Can you help us analyze it?

DaneLLL, Can you help us look at this problem?
