在stm32f107vc+DM9161AEP下应用Rt-Thread0.3.1，没有ping通，请朋友们帮忙看看哪里错了（
板子的配置为STM32F107VC+DM9161AEP在不用操作系统时可以调通，从其串口中也可以打印出DM9161的状态。ETH_ReadPHYRegister 0:0x3100

一共读了两次ETH的状态，一次为LWIP_INIT()之前，一次为LWIP_INIT()之后。两次寄存器的区别仅仅在于ETH_ReadPHYRegister(0,6):0x3和ETH_ReadPHYRegister(0,6):0x1；
我在手册上查了，
1位为A new link code word page received. This bit will be automatically cleared when the register (register 6) is read by management。
当在rt-thread中应用时，其串口打印的dm9161寄存器状态如下：

不用操作系统的时候可以ping通，现在ping不通。另外我上传了我的代码，请朋友们有时间用我看看。谢谢
传了一下午都没传成功附件，我QQ:370999235.
可以跟我QQ联系，共同探讨问题。 擦 标题Rt-Threadk1.3.1,真是猛料，版本更新真是神速! 一不小心写错了，一楼的朋友莫笑啊 默认情况下PHY并不需要配置就可以工作（默认PHY是自动协商的）
而现在的网络多是100M交换机，因此默认配置为100全双工就不用管PHY.
因各种板子太多，PHY的地址也不一样。
因此RT-Thread的SVN中的代码正考虑把PHY部分拿掉。这样拿到手不同的板子也比较容易调通。
当然，实际项目中还是要处理线路插拔及速率和双工状态的改变。
