I have configured the EventRecorder following the guide and the only events that I can see are EventRecorderInitialize and EventRecorderStart. Shouldn't µVision show more events or do I have to configure it properly or alter the code to do so?
you can upgrade your CMSIS pack to the latest v5.7.0 and Keil::ARM_Compiler pack to v1.6.3.
Afterwards, open your RTX_Config.h file and check if you have enabled all the necessary options for Event Recorder or not:

I found the solution at last! I had to use the RTX source variant. This information was really hidden in the documentation. It should be one of the first things at the top, since it is a prerequisite!
