Orin nx is connected to the switch chip, and the ip address will not disappear after unplugging the network cable

Orin nx connects and exchanges YT9218NH computer chips to generate network nodes. After unplugging the network cable, the ip address does not disappear.

Excuse me, what is this question? Is it related to the NVIDIA platform?
Send the board card to the switch chip manufacturer, saying that the switch chip works normally.

sdk:Tegra_Linux_Sample-Root-Filesystem_R36.4.3_aarch64.tbz2

Not sure what error this is. We don’t test such chip before.

4

Does orinx platform need to modify anything to debug the switch chip?
The board is powered on, and there is no access network cable, but this is displayed as link.

Could you provide your full dmesg too?

Looks like eth0 is a PCIe device on C9 added by you. The ethernet driver for it is not based on NV driver.

Please contact vendor for checking this first.

The switch chip is not connected to pcie, but connected to the orin nx chip.

Orin NX does not have RGMII interface or MGBE interface…

  1. The onboard ethernet interface on Orin NX/Nano is a PCIe interface connected to PCIe C8 on the module.

No matter what you connected, that thing is a PCIe device.

  1. I don’t see any interface enabled as “eth0” from PCIe C8 from your log. I only saw C9 becomes eth0.

6.054572] igb 0009:01:00.0: added PHC on eth0
[ 6.054609] igb 0009:01:00.0: Intel(R) Gigabit Ethernet Network Connection

If that is the interface you are talking about, then please check with Intel first.

There are now two NVIDIA core boards, Orinx and Xavier NX. The cut above may be from Xavier NX core board.

Please look at the text switch-log.txt and the figure below.

Hi,

我不確定用中文說明會不會比較清楚.

麻煩你就提供你現在有問題的那一片的log. 不用提供Xavier NX這些無管緊要的log出來.

請問這個是你所謂沒接線時候的狀態嗎?

15

是的，是没有接网线时的状态

17

請問一下你確定 enP8p1s0是你上圖所接的那個interface嗎?

我們用NV devkit在無接線的狀態下看到的結果是

netlink error: Operation not permitted
        Current message level: 0x00000033 (51)
                               drv probe ifdown ifup
	Link detected: no
18

enP8p1s0 是交换机芯片出来的节点。现在接上网线，ip地址就出现了。但是拔掉后ip地址一直在。

这个要配置设备树吗？

能請你抓一份有接線狀態下的dmesg嗎?

  1. 請問這個問題你們有用NV devkit複製過嗎?
  2. 請問不同的switch產生的結果有差別嗎
22

2个都没有。

这个芯片直接贴到底板上。
