TI中文支持网用NDK的hello world demo例程在开发板上运行演示正常。
但是在自制的板上程序下载后直接出现下图所示的状态：只有红色正方形的图标加亮显示，程序没有停在main函数，也不能通过CCS暂停运行。

请教一些调试排查的思路，有哪些因素会导致上述现象？
countryhotel：
用load symbal连上后，发现时停在函数configSerdes中等待状态上，因为板上时钟与开发板有差异，调整后已经可以正常运行
Shine：
请问你的板子上参考开发板的吗？能加载一些简单的例程吗？

回复 Shine:
参考了，就是芯片外部输入时钟做了部分调整，sgmii输入时钟我们用的是125M hz，phy芯片这些都是和参考设计一样的。clinet这些demo程序在修改时钟配置后都能跑了。
有问题正好咨询：
1 C6678 NDK tcp通信带宽大概能达到什么水平，我现在测试下来是15M Bytes左右，离理论值100M bytes差距太大；
2 论坛里有人说用开源的lwip能提高一些通信带宽？是否属实。官方有这方面的测试文档吗？
