不用仿真器，有办法么，我看到mcfw demo里面关于dsp和m3大量使用了一个Vps_printf函数打印一些东西实际运行时却是没有的，怎样才能看到这些信息呢，我想追踪下

大意就是你需要使能remote_debug_client.out
你好关于终端输出信息询问下，是不是Vps_printf的输出信息前面肯定是有类似[m3vpss ]、[c6xdsp ]如果是a8输出的话就是没有的
是的。类似于下图打印：
感谢你的回答，但是还是有点疑惑：
依次执行init.sh、load.sh和run.sh之后选择1模式：捕捉+编码+解码+显示。也就是:1: VCAP + VENC + VDEC + VDIS - Progressive SD Encode + Decode
我追踪McFw代码的时候，我记录了所有输出信息包括远程的m3和dsp,请看下面一段输出： [host] MCFW_IPCBITS:VcapVencVdecVdis_ipcBitsSendFxn:Entered...

[c6xdsp ] ALGLINK:HEAPID:0 USED:2832 [c6xdsp ] ALGLINK:HEAPID:1 USED:5536 从第3行开始到到33行都是A8的输出没错把，大部分是在一个System_init()函数及其子函数打印的。 首先这个System_init()有4个定义，我知道分别是a8、dsp、m3vpss和m3video的分别实现，问题是： 就我关注的dsp来说,下面这个打印出现在IpcFramesInLink_create()函数. [c6xdsp ] 1392086: IPC_FRAMES_IN : Create in progress !!! 调用关系如下: IpcFramesInLink_create()<--IpcFramesInLink_tskMain()<-IpcFramesInLink_init()<-System_init() 请注意这里的 System_init函数有4个定义但是针对dsp的情况我选择对应dsp的System_init 在dsp的System_init函数有这样的打印：#ifdef SYSTEM_DEBUG /*这个是有定义的*/ Vps_printf(" %d: SYSTEM : System DSP Init in progress !!!\n", Clock_getTicks());#endif 但是实际上串口是没有打印这一句的,后面还有很多句没有打印。 这是为什么？ 我认为m3vpss和m3video的System_init都有执行到，但是部分信息都没有打印出来这是为什么？
竟然在运行load.sh中发现上面本应该有的输出，能解释下么
你确定你的SYSTEM_DEBUG这个宏定义了吗？
你好我怀疑是先通过load.sh运行了两个m3和dsp也就是执行了System_init函数，然后一直等待a8的消息
