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：

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？

修改设备树将千兆改成百兆之后能够成功获取ip，感觉是配置千兆的时候哪里出问题了，目前就算百兆能执行udhcpc，但千兆不行，有大佬能指点下吗？

这种一般是千兆PHY没有配置好或者pcb布线的问题，需要调整tx_delay或者rx_delay
用的是野火的板子，用原来的固件是没问题的，所以首先排除PCB等硬件问题

问题解决了，也不是phy配置的问题，是uboot的网卡的设备树pin脚有一个没配好，不知道为什么会影响到kernel，kernel的设备树是没问题的，估计是uboot的引脚没释放吧，改了之后就没问题了
