Percepio Trace Recorder Initialization v4.6.0

|
|
|
|
This folder contains files that 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.
|
|
TraceRecorderInit 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, or simply
|
|
as early as absloutely possible. This will ensure the Trace Recorder is
|
|
initialized only once.
|
|
|
|
Set TRC_CFG_RECORDER_DATA_INIT to 0 in trcConfig.h to ensure
|
|
recorder data isn't initialized cleared after the recorder has been
|
|
already initialized.
|
|
|
|
It is possible that you also need to make sure certain recorder data isn't
|
|
cleared when RAM sections are initialized. Create a RAM section that isn't
|
|
cleared, then set the appropriate attribute in TRC_CFG_RECORDER_DATA_ATTRIBUTE.
|
|
This attribute will then be set for all necessary recorder data that should
|
|
not be cleared.
|
|
|
|
After the hardware and clocks are properly initialized, use
|
|
vTraceEnable(TRC_START) to start the tracing.
