The Code coverage feature only shows case detection inside of the Disassembly Window.Cortex-M7 targets) with J-Trace debug probes. General native Support for ETB and MTB tracing with J-Link and J-Trace debug probes.SWO trace with J-Link and J-Trace debug probes.Since V5.30 of the MDK-ARM the following features are supported: A general overview of the different trace types can be found here. Keil MDK supports various kinds of tracing features. The JLinkSettings.ini for a script file named like the settings file only with a different file extension. If no script file is explicitly passed to the DLL, it will search in the directory of The JLinkSettings.ini is a settings file created by the J-Link DLL on debug session start.
