The Cortex-M3 has a reduced capability ETM and does not support trace start/stop points or trace ranges. It only supports trace triggers via programming the Data Watchpoint and Trace (DWT) unit.
RVD does not support setting a trace trigger on the Cortex-M3. If any attempt is made to place trace control points (start/stop, ranges or triggers) in the debugger, the following error message will be generated:
Error V20019 (Vehicle): Logic Analyzer failed on request. See Output log.
Error: [TA0002] A resource required is not available
