TI中文支持网各位好！
问题RT：
硬件：自己的板卡
软件：基于Helloworld例程修改，替换了GEL等初始化
运行程序后，输出如下：
TCP/IP Stack 'Hello World!' Application
PASS successfully initializedEthernet subsystem successfully initializedEthernet eventId : 48 and vectId (Interrupt) : 7Registration of the EMAC Successful, waiting for link up ..
Network Added: If-1:192.168.2.100
从上面看，好像是已经初始化成功了，可是通过ping 192.168.2.100，会出现超时，或请求失败！请大神帮忙分析原因！谢谢！
PC IP是192.168.2.114

建议先看下SGMII SWITCH的SGMII_STATUS 状态寄存器的 LINK 状态标志位有没有LINK UP起来
然后检查STAT统计模块有没有正常的收发包统计，一步一步排查，光看代码很难发现问题

回复 Thomas Yang1:
Thomas Yang1 你好！
我在调试sgmii的时候，现在SGMII_STATUS 状态寄存器的 LINK 状态标志位时没有LINK UP起来，一直处在do..while循环当中，造成没有LINK UP起来的原因主要是什么呢？

没有连上，可能是自动协商没有通过
shuang li3：
你好。
最近我也在进行C6678网口的调试，使用gel初始化之后能够实现和PC端的通信。
但是现在想不用gel文件来实现板子的初始化，然而网口的bios程序默认分配在DDR3内部运行的，如果不先使用gel文件初始化ddr3，那么程序就跑不到main的位置。
想请教你是用什么方法来让程序运行到main函数，然后再对DDR3进行初始化的。谢谢

前几天我也遇到这个问题，最后是serdes的时钟配置不对，我把0x51改为0x41就对了.
