RK3128 網路無法正常啟動
各位先進好，目前正在開發RK3128網路功能，遇到網路只有在開機第一次會做初始化的動作，查看系統中的carriar沒有變化，不知道是哪邊沒有做好設定，導致插拔網路線不會重新初始化。
其相關log如下

插拔网线是自动识别的，有多台的机器的话，可以再验证下
試過多個機器，其結果都相同，有發現系統carriar的狀態 (/sys/class/net/eth0/carrier)不會改變
開機沒接網路線 狀態為0
接上網路線後 狀態為1
猜測，其狀態不會改變，進而導致狀態異常
但這是什麼問題呢? kevin.chen 发表于 2019-12-16 14:50

我拿了一个firefly-rk3128的机器验证是没有你说的问题。如下log是我插拔网线的相关信息，所以你需要自己检查一下是哪个地方出问题。
同时我看了你log打印是后面识别到是100M的速度，可以换个网线试试。

感謝您的驗證，想請問您使用的kernel的版本是哪一版，因為有看到資訊顯示kernel版本有問題，但不是很確定版本。
另外，剛剛又透過量訊號，發現MDIO 在接上網路線後，便不會主動的去poll網路的狀態，不知道MDIO是否有相關設定經驗可以分享呢? kevin.chen 发表于 2019-12-16 16:34

我现在使用的是3.10的内核，还有如果你底板是自己layout，需要自己检查一下硬件。 問題已解決。
發現問題是 phy的驅動設定錯誤，有個flag未設定好，導致不會自動poll網路狀態。
謝謝大家
