3. 代码中创建了两个进程，进程内部打印进程信息

4. 修改BearPi-Hm_Nano/sample下的build.gn，指定thread_example

5. 在putty连接并且切换到project目录后，输入hpm dist进行编译

   

6. 把虚拟机中out/Hi3861_wifiiot_app_allinone.bin复制到windows，用Hiburn进行烧录

7. baud设置为921600，点击connect

8. 按下开发板上的reset键，开始下载

   

9. 千万别忘记勾选auto burn选项！

   

10. 在putty进行捕捉串口日志

11. 点击session-logging如图设置

    

12. 选择serial，设置com号，速率设为115200

13. 实验结果：
