 Since SystemView tool is mostly intended for OS level analysis. It allows just to inspect custom events' timestamps and parameters. So it can require some efforts to analyse heap operations flow. IDF provides special script to make the life a bit more easy. This script parses SystemView trace file sand reports detected memory leaks. The script also prints found log messages. To run it type the following from the project root directory:
 
 ```
-$IDF_PATH/tools/esp_app_trace/sysviewtrace_proc.py -p /tmp/heap_log.svdat build/sysview_tracing_heap_log.elf
+$IDF_PATH/tools/esp_app_trace/sysviewtrace_proc.py -p -b build/sysview_tracing_heap_log.elf /tmp/heap_log.svdat

 Below is the sample scripts output.
