QUESTION

Previously I used System and Thread Viewer debug feature forprojects using CMSIS-RTOS v1 (Keil RTX v4.x). 

After switching to use CMSIS-RTOS v2 (Keil RTX v5.x) in myproject, System and Thread Viewer in debug session stays blank.

How can I make System and Thread Viewer work with RTX v5?

ANSWER

System and Thread Viewer debug window doesn't support debuggingCMSIS-RTOS v2 (Keil RTX v5.x).

As an alternative to System and Thread Viewer, in MDK versionsnewer than v5.21 you can use Component Viewer 'RTX RTOS' to debugprojects using CMSIS-RTOS v2(Keil RTX v5.x), as shown in this screenshot.
