 + jlink包安装  
 
 第一步，进入jlink官网[下载网址](https://www.segger.com/downloads/jlink)

 第二步，安装openocd
-    
-    $ sudo mv kendryte-openocd-0.2.2-ubuntu64.tar.gz /opt
-    $ cd /opt
-    $ sudo tar -zxvf kendryte-openocd-0.2.2-ubuntu64.tar.gz

 第三步，openocd文件配置  
 
 打开配置文件，修改第三行 jlink serial 504503073的504503073为具体JLINK设备的标签。
 
-    $ cd /opt/kendryte-openocd
-    $ vim ctl/openocd.cfg

 第四步，打开openocd软件  
 
-    $ cd /opt/kendryte-openocd
-    $ ./bin/openocd -f ./ctl/openocd.cfg
+```shell
+$ cd /opt/kendryte-openocd
+$ ./bin/openocd -f ./ctl/openocd.cfg

+
+点击调试后，若未设置断点，Ozone将自动在执行main函数前停止，Ozone支持设置代码和数据断点、单步调试、查看变量值等功能，是很方便的一个调试工具。
