AWR1642BOOST: 下位机无法接收上位机发送的串口指令

尊敬的TI工程师你好，我用AWR1642BOOST 测试driver vital signs 的时候前一天还是正常的，第二天测试时上位机GUI就不显示图形了，结果如下：

QT version =  5.9.1
QMetaObject::connectSlotsByName: No matching signal for on_buttonBox_accepted()
Serial Port Found
Data Port Number is "COM5"
User Port Number is "COM4"
Data port succesfully Open
User port succesfully Open
Configuration File Name Read from the GUI is %s/n "xwr1642_profile_VitalSigns_20fps_Back.cfg"
QMetaObject::connectSlotsByName: No matching signal for on_buttonBox_accepted()
"COM4"
Configuration File Path is %s/n "D:/tools/labs/lab0001-driver-vital-signs/vitalSigns_host/profiles/xwr1642_profile_VitalSigns_20fps_Front.cfg"
"sensorStop"
"flushCfg"
"dfeDataOutputMode 1"
"channelCfg 15 3 0"
"adcCfg 2 1"
"adcbufCfg -1 0 0 1 0"
"profileCfg 0 77 7 6 57 0 0 70 1 200 4000 0 0 48"
"chirpCfg 0 0 0 0 0 0 0 1"
"frameCfg 0 0 2 0 50 1 0"
"lowPower 0 1"
"guiMonitor 0 0 0 0 1"
"calibDcRangeSig -1 0 0 0 0"
"vitalSignsCfg 0.3 0.9 256 512 4 0.1 0.05 100000 300000"
"motionDetection 1 20 2.0 0"
"sensorStart"
""

我尝试用UniFlash重新烧录下位机程序的时候,出现错误，结果如下：

[2022/9/19 上午10:59:04] [INFO] Cortex_R4_0: Reset connection to device
[2022/9/19 上午10:59:04] [INFO] Cortex_R4_0: Set break signal

请问这个要怎么解决

请按照下面帖子里的建议检查，先看一下PC的串口是否有问题，串口线是否好的，其他会用到串口的软件要关闭。https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1017510/iwr6843aop-image-loading-failed-not-able-to-connect-to-serial-port-recheck-com-port-selected-and-or-permissions
