将C6678的前四个核进行同步，使用的是IPC_start函数

从注释信息来看，这是可能是代码被改写所致，希望大家帮忙看看，有什么好的方法解决这个问题，谢谢

    PC=0？ 感觉程序跑飞了，挂上仿真器单步跟踪看看吧

    本人设置了四个核同步，经过单步调试，当三个核运行在IPC_start函数等待，这时最后一个核单步运行到IPC_start函数后，正常情况是四个经过同步一起出来，再执行下一步。而现在四个核真正运行到IPC_start函数时，除了上图所示的情况。（本次做的是将NDK的UDP例程与MessageQ进行融合）

    你先剥离下UDP和MESSGEQ，看下如果单独运行MESSAGE Q是否正常，
