ti专家，您好,我们现在正在做C6670与marvell 88e6122交换芯片的一个项目，正在调试网口，目前处于阻塞状态，想运行mcsdk里的6670 ndk的hellowrold例程，并且设置成静态IP地址，例程运行后，pc侧ping不通我设定的ip地址，协议栈启动之前对sgmii与phy芯片进行了设置，并且已经查看到已经sgmii与phy的状态已经linkup上了。使用k1_stk_v1.1中GE例程,进行外部回环测试，没有问题。（我们的板卡跟EVM开发板的系统时钟、SGMII参考时钟不同，对两个例程分别做了相应修改，EVM系统时钟为122.88M，SGMII为250M，我们的板卡系统时钟为153.6，SGMII时钟为156.25）

还有另外一个问题：
看TI Network Developer's Kit (NDK) v2.21文档时，说需要重新编译ndk库文件，但通过ccs进行加载时根本找不到工程，ndk目录下有相应的ndk.mak文件，所以无法对库进行重新编译。
开发环境 CCS 5.2
NDK 版本 ndk_2_21_01_38
