TI中文支持网我使用IWR1642 Boost，运行mmwave_industrial_toolbox_4_2_0__win里面的16xx_high_accuracy例程，我用串口工具发送CLI命令到IWR1642，发送完high_accuracy_demo_16xx.cfg里的命令后程序正常运行，然后我用串口发送"sensorStop"命令，CCS上提示mmWave_stop失败，串口操作界面和CCS提示信息如下：

请问怎么解决这个问题？
Chris Meng：
你好，
建议你可以进一步跟踪一下代码，看看具体错误在那里。
你可以对比mmw demo里面的sensorstop命令的实现。

回复 Chris Meng:
找到原因了，为了逐行调试，我把工程的优化等级关闭了，然后会导致这个错误产生。
但我不明白为什么会跟优化等级有关，能否解释一下呢？
Chris Meng：
回复 wanrong xie:
你好，
可能是MSS/DSS的同步没有做的很好。
