移植st官方的en.SOURCES-stm32mp1-openstlinux-5-4-dunfell-mp1-20-06-24.tar到开发板上，设备树参考野火的设备树进行修改，通过网线将网口直接连接电脑使用静态ip设置能够ping通，然后将网口接到路由器，使用dhcpc命令获取动态ip无法获取ip，请问有知道怎么解决吗？

开关eth0会报如下错误：

动态获取ip一直是这样：
root@lubancat:~# udhcpc -i eth0
udhcpc: started, v1.30.1
udhcpc: sending discover

使用静态IP ping电脑是没问题的

感觉像设备树还是驱动没移植成功

连上wifi执行udhcpc命令是能动态获取ip的，证明动态获取ip相关配置应该是没问题的

但获取eth0的动态ip就是不成功，是设备还是驱动需要修改？有大佬知道吗？
