RT1176 ENET PHY调试问题

[lzfranky]

问题：使用DP83848 PHY RMII模式，通过RT1176 M7 MDIO接口可以控制PHY芯片自动协商完成，但是TX DATA 0,1，RX DATA 0,1没有数据？软件已经运行到下面ENET_SendFrame,就是不能发送数据

调试信息如下：

etharp_timer

Hi,

感谢回复。

1） 有没有方法可以读取RT1176寄存器，可以确定RMII接口配置正确？

-- 很多IDE在debug时，都是可以查看外设寄存器的具体值的。

Have a great day,

Hi,
非常感谢使用NXP产品，很高兴为你提供技术支持！
在找到问题之前，我想知道你的测试环境，比如开发板，测试代码（如果使用SDK库中的代码，是否做了修改）等。
Have a great day,
