/*
* Percepio Trace Recorder Initialization v4.6.0
* Copyright 2021 Percepio AB
* www.percepio.com
*
* SPDX-License-Identifier: Apache-2.0
*
* This file should only be included in a project if there is a need to
* initialize the Trace Recorder before main() has been called.
* An example of this scenario is if you have a global object instance that has
* a constructor that creates an object that should be traced.
* This file will make it easier to initiate the recorder correctly.
*
* Usage:
* Add a call to TraceRecorderInit::Initialize() wherever a traced object is
* created before the Trace Recorder is normally initialized. This will ensure
* the Trace Recorder is initialized only once.
*
* Set TRC_CFG_RECORDER_DATA_PTR_INIT to 0 in trcSnapshotConfig.h to ensure
* RecorderInitialized isn't initialized to 0 after the recorder has been
* already initialized.
*
* Finally, call vTraceEnable(TRC_START) after hardware is initialized to
* start gathering trace events.
