secureCRT 日志保存并记录每条记录的时间

对于嵌入式工程师来说，和设备交互是工作中必不可少的事。

在同事中串口工具一般都是使用secureCRT 和Xshel  ，具体那个好在此不做讨论。我觉得都很好，看个人喜好。

对于嵌入式系统工程师来说，系统的启动时间是个重要指标。因此能够准确测量系统每个模块所用时间尤其重要。

下面介绍一下在使用secureCRT过程中一个很好用的技巧，保存每条记录并打印记录的时间

先看看保存日志的效果

以上是Linux启动过程中保存的log日志，嵌入式系统工程师是否很兴奋。启动的每个过程都有时间。怎么做的？

打开secureCRT   工具栏的《选项》--《回话选项》就弹出上图。点击《日志文件》--《在每行》中添加     %h:%m:%s:%t  确定

此时配置已经完毕。下一步 工具栏  《文件》---选中《会话位置》，选择log日志存放位置。

重启系统之后，再断开串口链接查看日志
