网卡驱动 dp83848

doudoujingxin

各位好：我现在使用的是ok335xS的板子，使用的网卡是AR8031，如果我想换成DP83848，请问需要怎么修改呢，忘指点

AR8031 跟 DP83848 的接口总线不同，所用的时钟也不相同，所用的PHY的ID也不一样，修改的话，需要修改接口类型，PHY ID，时钟来源。还有一点提醒一下:注意一下dp83848是不是还适用？

现在调试能ping通，但是丢包严重，能达到20%，请问这是什么原因啊

你换一块同样的板子试试，看看还有这个原因吗

doudoujingxin

试了，都一样，现在使用FET335xS_V2.0的核心板，外加我们自己的底板，测试了两块都是这样，不知是什么原因啊。

doudoujingxin

求各位大神给个回复吧，有遇到这种情况的吗

中国加油

自己做底板的话，容易出现网口有问题，lz 底板中网口有复位电路吗？

请问改为使用dp83848是否需要修改phy 的驱动

可以参考我们2014年的资料，老版资料是有的
