DM6467T Sending DHCP requests .. PHY: 1:01 – Link is Up – 1000/Full …. timed out!

大家好：

板子为：TMS320DM6467T 用 tftp 传入了官方的uImage-dm6467t-evm.bin文件，启动时提示：

Sending DHCP requests .. PHY: 1:01 – Link is Up – 1000/Full …. timed out!

希望能得到大神们的解答！

求大神们帮帮忙吧！！！

Louis：

   从你的描述中，看出你在Uboot下的网络是通的，当启动内核的时候，DHCP失败。 初步判断是你使用的linux内核的网络部分与你的板子不匹配。请确认一下官方的原理图与你的板子在网络部分是否一致。另外，也可以根据你的具体硬件，修改内核中网络部分的配置，然后重新编译，再使用新编的内核看看。

Louis
