[参考译文] DP83640：IMX7D MII 器件树

https://e2e.ti.com/support/interface-group/interface/f/interface-forum/1025823/dp83640-imx7d-mii-device-tree

下午好！

我目前有一个定制电路板、其中 iMX7d (在 EA iMX7d uCOM SOM 上)通过 MII 连接到 DP8360 PHY、我似乎无法通过 MII 接口使通信正常工作。 通过 MDIO 总线正确发现和配置 PHY、我可以看到从 uBoot 在 Wireshark 中发送的 TX 数据包。 希望我错过了器件树中的某个东西、

当前设备树、
