   了解了一下TraceAlyzer，其实是一个OS时序分析软件.不过强大的功能却要收费，这里看到有FreeRTOS使用的免费版本，下载来看看。
   需要填写几个表单

实验的工程中要添加trace的支持代码，是按照中间件提供的，如下

这个目录是这个样子的

readme.txt
│ trcKernelPort.c
│ trcSnapshotRecorder.c
│ trcStreamingRecorder.c
├─config
│ trcConfig.h // 整个Trace源码的配置文件.
│ trcSnapshotConfig.h // 快照模式配置文件，和流模式对应文件选其一
│ trcStreamingConfig.h // 流模式配置文件，和快照模式对应文件选其一
├─include
│ trcHardwarePort.h // 所有硬件依赖关系。包含几个预定义的硬件端口，包括ARM Cortex-M，PIC32，Renesas RX等。
│ trcKernelPort.h // FreeRTOS特定的定义，最值得注意的是跟踪钩子定义。
│ trcPortDefines.h // 配置文件的各种常量定义
│ trcRecorder.h // 公共API,开发者将以上两种模式进行了统一，用户使用时，只需要包含该文件即可!
└─streamports // 该文件夹下就是流模式对应的不同接口方式的实现，以下任选其一即可
├─Jlink_RTT

│ │ SEGGER_RTT.c

另外要在trcConfig文件中修改一些内容，重点看有注释的地方。

* is exceeded, the particular ISR will not be traced and the recorder then
* logs an error message. This setting is used to allocate an internal stack
* for keeping track of the previous execution context (4 byte per entry).
