你好，
jetpack6.0 系统刷完之后，数据线连接OTG接口和主机，主机上不能ping 不通192.168.55.1 似乎没有连接，在jetpack5.1上是可以的，请问这是什么原因？谢谢
custom board的話麻煩檢查nv-l4t-usb-device-mode.service這個service的狀態
開不起來的話syslog裡應該會有error
这个服务正在active,如下：
● nv-l4t-usb-device-mode.service - Configure USB flashing port for device mode

主机上还是没有l4t-readme,还是ping不通 192.168.55.1
能請你分享全整的dmesg然後附成一個檔案嗎？
demsg:
dmesg.log (67.0 KB)
你這不是NV devkit吧？
是的 属于custom board。
看來device tree沒改過? usb device mode沒triggered.
以前jp5.1能動大概也是巧合, 在usb上很常見
是的，device tree没有改动，那么我需要修改设备树上哪里呢？应该怎么修改呢？谢谢！
查看完文档，需要修改的也就是添加connector,同时，也参考了jetpack5.1的设备树设置，在usb2_0节点下添加节点：
connector {
compatible = “usb-b-connector”, “gpio-usb-b-connector”;
label = “micro-USB”;
type = “micro”;
vbus-gpio = <&gpio TEGRA234_MAIN_GPIO(Z,1) GPIO_ACTIVE_LOW>;
};
编译出的设备树替换到设备后并没有解决问题，请问还需要添加或者修改哪里吗？谢谢
基本上你問也沒辦法給你答案
device tree是要搭配硬體線路圖才知道有沒有寫對…
我們不知道你的板子是設計成怎樣
你好 WayneWWW，
我们是刷完jetpack6.0系统之后，orin nx 已经进入到系统中，正常情况下，这个时候主机与orin nx 通过数据线连接后，主机可以通过ping 命令,ping 通orin nx 的IP192.168.55.1，但是，现在orin nx 开机后，通过数据线与主机连接，主机ping不通。我们的custom board的OTG在xavier nx ,nano 模块上都是正常使用的。但是安装完jetpack6.0系统后，这个接口就不行了，麻烦提供一下帮助，谢谢
請問你重複一次問題的意思是什麼？
前面不是已經解釋過你的問題所在了？
There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks
而且這句話到底在講什麼？ 正常情況下可以動, 開機後不能動.
所以開機不是正常情況？
