Other Parts Discussed in Thread: TVP7002

请大家帮忙分析一下：
我使用的DM8148EVM_REV.D       DVRRDK3.0 进行调试
 
我的程序是跑的视频用tvp7002按照720P采集，编码网络发送出去；
如果再启动经行音频采集，视频采集模块会出现问题，出现下面的打印；
如果先经行音频采集，视频采集模块启动失败,程序执行到
System_linkCreate (captureId, &capturePrm, sizeof(capturePrm)); )，
程序就挂了，就可以看到下面的打印。
 
音频采集用程序跑和arecord跑对视频采集的影响效果都是一样的。
