DSPS v_5.150.2 error message when debug in Keil. << No Cortex M SW Device Found >>

嗨对话框支持团队,

We are trying to get the DSPS program to work. The version we are using is from DSPS v_5.150.2. Project compiles fine but when opening the debug window in Keil uVision, the error message "No Cortex M SW Device Found" was shown. We do not encounter such problem with other project files. When using DSPS v_3.150.2, no such error but unable to detect the device on the mobile app. Any advise is greatly appreciated. Prefer to work with V5.150.2 as that allows change of pins for the HW flow control.
