TI中文支持网Part Number:IWR6843ISKOther Parts Discussed in Thread: DCA1000EVM, MMWAVEICBOOST, UNIFLASH
我今天使用IWR6843ISK+MMWAVEICBOOST+DCA1000EVM进行测试，大约使用了3个小时后，修改传感器参数时出现报错（在此之前一直可以正常采集数据，且使用过多次），发现是RS232连接断开，重新尝试连接则会出现报错信息：[RadarAPI]: Error: Connection failed: Calling_ConnectTarget returned 3. 在论坛上对相关问题进行搜索后，经过如下诸多尝试仍无法解决：
1. 确认线缆连接正常、端口选择正确，且端口可以在其它的串口调试软件中打开；
2. 确认电源供电正常，且更换了备用的5V 2.5A电源；
3. 确认编码开关和跳线帽在断电情况下按照手册要求设置正确；
4. 重启电脑、更换其它电脑、重新安装mmWave Studio 2.1.1.0；
5. 使用Uniflash擦除flash，端口与mmWave Studio中选择相同，遇到报错：Not able to connect to serial port. Recheck the COM port selected.

Chengyu Zhu：
补充：将IWR6843ISK单独取下后，可以使用Uniflash擦除flash和烧写，但是装到MMWAVEICBOOST上后仍然无法连接

Chris Meng：
你好，
是否尝试过ISK直接和DCA1000EVM配合使用，不用ICBOOST，看是否能正常工作？
Thanks，
Chris

Chengyu Zhu：
你好，我尝试了几次，每次都在重启电脑并重新插拔ISK上的Micro USB后可以正常工作，此时如果重新连接Micro USB或关闭并重新上电，就会遇到和先前同样的报错，或是在设备管理器中直接无法找到ISK的端口，只有重启电脑并同时重新插拔ISK上的Micro USB线缆才能再次识别，而且无法找到ISK端口的时候，ISK上的USB指示灯也不会亮起（即使单独作为模块使用，使用USB供电也会这样），操作系统再次能够成功识别后才会亮起。
另外，同样的操作对使用MMWAVEICBOOST时不管用，我尝试了2次给MMWAVEICBOOST上的XDS110重新烧录3.0.0.29版本固件，第一次直接变砖，第二次在断电情况下短接JTAG TDO和GND后冷启动进入DFU模式，重新烧录固件成功，重启电脑后ICBOOST有时就可以正常工作了（之前完全无法使用），但该问题还是会不时出现。
