hi，根据官网的案例，我们最终按照nvidia,phy-reset-gpio = \<&gpio TEGRA234\_MAIN\_GPIO(G, 5) 0\>;进行设置，依旧还是nvethernet -19。 我们尝试执行sudo ip link set eth0 up，发现PHYRSTB复位后，MDC没有输出，能否帮忙确认一下原因。 ![image](https://global.discourse-cdn.com/nvidia/original/4X/0/a/c/0aceb95d1ff1a9f5be45e501878bf2a13830cc3a.jpeg) [Next page](https://forums.developer.nvidia.com/t/topic/379104.md?page=2)
