Configure instruction trace in Embedded Studio
In general, to get ETB up and running, just make sure to configure ETB as Trace Interface Type in the Embedded Studio project settings:
Debugger --> Target Trace Options --> Trace Interface Type --> ETB
Once the debug session has been started, the most recent executed instructions will be shown in the instruction backtrace window. The window can be opened at:
Debug --> Other windows --> Execution Trace
