* trcConfig.h
*
* Configuration parameters for the trace recorder library. Before using the
* trace recorder library, please check that the default settings are
* appropriate for your system, and if necessary adjust these. Most likely, you

* reflect the number of such objects in your system. These may be
* over-approximated, although larger values values implies more RAM usage.

* Tracealyzer groups the events into actor instances, based on context-switches
* and a definition of "Instance Finish Events", or IFEs. These are kernel calls
* considered to be the last event in a task instance. Some kernel calls are
* considered IFEs by default (e.g., delay functions), but it is also possible
* to specify this individually for each task (see vTraceTaskInstanceFinish).
*
* If USE_IMPLICIT_IFE_RULES is one (1), the default IFEs will be enabled, which
* gives a "typical" grouping of events into instances. You can combine this
* with calls to vTraceTaskInstanceFinish for specific tasks.
*
* If USE_IMPLICIT_IFE_RULES is zero (0), the implicit IFEs are disabled and all
* events withing each task is then shown as a single instance, unless you call

/******************************************************************************
* USE_16BIT_OBJECT_HANDLES
*
* Macro which should be defined as either zero (0) or one (1).
*
* If set to 0 (zero), the recorder uses 8-bit handles to identify kernel
* objects such as tasks and queues. This limits the supported number of
* concurrently active objects to 255 of each type (object class).
*
* If set to 1 (one), the recorder uses 16-bit handles to identify kernel
* objects such as tasks and queues. This limits the supported number of
* concurrent objects to 65535 of each type (object class). However, since the
* object property table is limited to 64 KB, the practical limit is about
* 3000 objects in total.
*
* Default is 0.
*
* NOTE: An object with handle above 255 will use an extra 4-byte record in
* the event buffer whenever referenced. Moreover, some internal tables in the
* recorder gets larger when using 16-bit handles. The additional RAM usage is

* this separate buffer has the benefit of not overwriting the user events with
* kernel events (usually generated at a much higher rate), i.e., when using

*
* HWTC Macros
*
* These four HWTC macros provides a hardware isolation layer representing a
* generic hardware timer/counter used for driving the operating system tick,
* such as the SysTick feature of ARM Cortex M3/M4, or the PIT of the Atmel
* AT91SAM7X.
* These macros provides a hardware isolation layer representing the
* hardware timer/counter used for the event timestamping.
*
* TRC_HWTC_COUNT: How to read the current value of the timer/counter.
*
* TRC_HWTC_TYPE: Tells the type of timer/counter used for TRC_HWTC_COUNT:
*
* HWTC_COUNT: The current value of the counter. This is expected to be reset
* a each tick interrupt. Thus, when the tick handler starts, the counter has
* already wrapped.
* - TRC_FREE_RUNNING_32BIT_INCR:
* Free-running 32-bit timer/counter, counting upwards from 0.
*
* HWTC_COUNT_DIRECTION: Should be one of:
* - DIRECTION_INCREMENTING - for hardware timer/counters of incrementing type
* such as the PIT on Atmel AT91SAM7X.
* When the counter value reach HWTC_PERIOD, it is reset to zero and the
* interrupt is signaled.
* - DIRECTION_DECREMENTING - for hardware timer/counters of decrementing type
* such as the SysTick on ARM Cortex M3/M4 chips.
* When the counter value reach 0, it is reset to HWTC_PERIOD and the
* interrupt is signaled.
* - TRC_FREE_RUNNING_32BIT_DECR
* Free-running 32-bit timer/counter, counting downwards from 0xFFFFFFFF.
*
* HWTC_PERIOD: The number of increments or decrements of HWTC_COUNT between
* two OS tick interrupts. This should preferably be mapped to the reload
* register of the hardware timer, to make it more portable between chips in the
* same family. The macro should in most cases be (reload register + 1).
* For FreeRTOS, this can in most cases be defined as
* #define HWTC_PERIOD (configCPU_CLOCK_HZ / configTICK_RATE_HZ)
* - TRC_OS_TIMER_INCR
* Periodic timer that drives the OS tick interrupt, counting upwards
* from 0 until (TRC_HWTC_PERIOD-1).
*
* HWTC_DIVISOR: If the timer frequency is very high, like on the Cortex M chips
* (where the SysTick runs at the core clock frequency), the "differential
* timestamping" used in the recorder will more frequently insert extra XTS
* events to store the timestamps, which increases the event buffer usage.
* In such cases, to reduce the number of XTS events and thereby get longer
* traces, you use HWTC_DIVISOR to scale down the timestamps and frequency.
* Assuming a OS tick rate of 1 KHz, it is suggested to keep the effective timer
* frequency below 65 MHz to avoid an excessive amount of XTS events. Thus, a
* Cortex M chip running at 72 MHZ should use a HWTC_DIVISOR of 2, while a
* faster chip require a higher HWTC_DIVISOR value.
* - TRC_OS_TIMER_DECR
* Periodic timer that drives the OS tick interrupt, counting downwards
* from TRC_HWTC_PERIOD-1 until 0.
*
* The HWTC macros and vTracePortGetTimeStamp is the main porting issue
* or the trace recorder library. Typically you should not need to change
* the code of vTracePortGetTimeStamp if using the HWTC macros.
* - TRC_CUSTOM_TIMER_INCR
* A custom timer or counter independent of the OS tick, counting
* downwards from TRC_HWTC_PERIOD-1 until 0. (Currently only supported
* in streaming mode).
*
* - TRC_CUSTOM_TIMER_DECR
* A custom timer independent of the OS tick, counting downwards
* from TRC_HWTC_PERIOD-1 until 0. (Currently only supported
* in streaming mode).
*
* TRC_HWTC_PERIOD: The number of HWTC_COUNT ticks until the timer wraps
* around. If using TRC_FREE_RUNNING_32BIT_INCR/DECR, this should be 0.
*
* TRC_HWTC_FREQ_HZ: The clock rate of the TRC_HWTC_COUNT counter in Hz. If using
* TRC_OS_TIMER_INCR/DECR, this is should be TRC_HWTC_PERIOD * TRACE_TICK_RATE_HZ.
* If using a free-running timer, this is often TRACE_CPU_CLOCK_HZ (if running at
* the core clock rate). If using TRC_CUSTOM_TIMER_INCR/DECR, this should match
* the clock rate of your custom timer (i.e., TRC_HWTC_COUNT). If the default value
* of TRC_HWTC_FREQ_HZ is incorrect for your setup, you can override it by calling
* vTraceSetFrequency before calling vTraceEnable.
*
* TRC_HWTC_DIVISOR (used in snapshot mode only):
* In snapshot mode, the timestamp resolution is TRC_HWTC_FREQ_HZ/TRC_HWTC_DIVISOR.
* If the timer frequency is very high (hundreds of MHz), we recommend increasing
* the TRC_HWTC_DIVISOR prescaler, to reduce the bandwidth needed to store
* timestamps. This since extra "XTS" events are inserted if the time since the
* previous event exceeds a certain limit (255 or 65535 depending on event type).
* It is advised to keep the time between most events below 65535 native ticks
* (after division by TRC_HWTC_DIVISOR) to avoid frequent XTS events.

* Supported ports
*
* TRC_HARDWARE_PORT_HWIndependent
* A hardware independent fallback option for event timestamping. Provides low
* resolution timestamps based on the OS tick.
* This may be used on the Win32 port, but may also be used on embedded hardware
* platforms. All time durations will be truncated to the OS tick frequency,
* typically 1 KHz. This means that a task or ISR that executes in less than
* 1 ms get an execution time of zero.
*
* TRC_HARDWARE_PORT_APPLICATION_DEFINED
* Allows for defining the port macros in other source code files.
*
* TRC_HARDWARE_PORT_Win32
* "Accurate" timestamping based on the Windows performance counter for Win32
* builds. Note that this gives the host machine time, not the kernel time.
*
* Hardware specific ports
* To get accurate timestamping, a hardware timer is necessary. Below are the
* available ports. Some of these are "unofficial", meaning that
* they have not yet been verified by Percepio but have been contributed by
* external developers. They should work, otherwise let us know by emailing
* support@percepio.com. Some work on any OS platform, while other are specific
* to a certain operating system.

* which is stored in the recorder's symbol table.
* When logging a user event, a numeric handle (reference) to this string is
* used to identify the event. This is obtained by calling
*
* xTraceOpenLabel()
*
* whihc adds the string to the symbol table (if not already present)
* and returns the corresponding handle.
*
* This can be used in two ways:
*
* 1. The handle is looked up every time, when storing the user event.
*
* Example:
* vTraceUserEvent(xTraceOpenLabel("MyUserEvent"));
*
* 2. The label is registered just once, with the handle stored in an
* application variable - much like using a file handle.
*
* Example:
* myEventHandle = xTraceOpenLabel("MyUserEvent");
* ...
* vTraceUserEvent(myEventHandle);
*
* The second option is faster since no lookup is required on each event, and

* however fairly fast due to the design of the symbol table.

* stores the arguments. The actual formatting is done
* on the host PC when the trace is displayed in the viewer tool.
*
* User Event labels are created using xTraceOpenLabel.
* Example:
*
* traceLabel adc_uechannel = xTraceOpenLabel("ADC User Events");
* ...
* vTracePrint(adc_uechannel,
* "ADC channel %d: %lf volts",
* ch, (double)adc_reading/(double)scale);

*
* vTracePrint(xTraceOpenLabel("ADC User Events"),
* "ADC channel %d: %lf volts",
* ch, (double)adc_reading/(double)scale);
*
* Calling xTraceOpenLabel multiple times will not create duplicate entries, but
* it is of course faster to just do it once, and then keep the handle for later
* use. If you don<EFBFBD>t have any data arguments, only a text label/string, it is
* better to use vTraceUserEvent - it is faster.
*
* Format specifiers supported:
* %d - 32 bit signed integer
* %u - 32 bit unsigned integer
* %f - 32 bit float
* %s - string (is copied to the recorder symbol table)
* %hd - 16 bit signed integer
* %hu - 16 bit unsigned integer
* %bd - 8 bit signed integer
* %bu - 8 bit unsigned integer
* %lf - double-precision float (Note! See below...)
*
* Up to 15 data arguments are allowed, with a total size of maximum 32 byte.
* In case this is exceeded, the user event is changed into an error message.
*
* The data is stored in trace buffer, and is packed to allow storing multiple
* smaller data entries in the same 4-byte record, e.g., four 8-bit values.
* A string requires two bytes, as the symbol table is limited to 64K. Storing
* a double (%lf) uses two records, so this is quite costly. Use float (%f)
* unless the higher precision is really necessary.
*
* Note that the double-precision float (%lf) assumes a 64 bit double
* representation. This does not seem to be the case on e.g. PIC24 and PIC32.
* Before using a %lf argument on a 16-bit MCU, please verify that
* "sizeof(double)" actually gives 8 as expected. If not, use %f instead.

* etc.) Note: 255, not 256, since handle 0 is reserved.
*
* If set to 1 (one), the recorder uses 16-bit handles to identify kernel
* objects such as tasks and queues. This limits the supported number of
* concurrent objects to 65535 of each type (object class). However, since the
* object property table is limited to 64 KB, the practical limit is about
* 3000 objects in total.
*
* Default is 0 (8-bit handles)
*
* NOTE: An object with handle above 255 will use an extra 4-byte record in
* the event buffer whenever the object is referenced. Moreover, some internal
* tables in the recorder gets slightly larger when using 16-bit handles.

*
* Macro which should be defined as an integer value.
*
* Set TRC_CFG_USE_SEPARATE_USER_EVENT_BUFFER to 1 to enable the
* separate user event buffer (UB).
* In this mode, user events are stored separately from other events,
* e.g., RTOS events. Thereby you can get a much longer history of
* user events as they don't need to share the buffer space with more
* frequent events.
*
* The UB is typically used with the snapshot ring-buffer mode, so the
* recording can continue when the main buffer gets full. And since the
* main buffer then overwrites the earliest events, Tracealyzer displays
* "Unknown Actor" instead of task scheduling for periods with UB data only.
*
* In UB mode, user events are structured as UB channels, which contains
* a channel name and a default format string. Register a UB channel using
* xTraceRegisterUBChannel.
*
* Events and data arguments are written using vTraceUBEvent and
* vTraceUBData. They are designed to provide efficient logging of
* repeating events, using the same format string within each channel.
*
* Examples:
*
* traceString chn1 = xTraceRegisterString("Channel 1");
* traceString fmt1 = xTraceRegisterString("Event!");
* traceUBChannel UBCh1 = xTraceRegisterUBChannel(chn1, fmt1);
*
* traceString chn2 = xTraceRegisterString("Channel 2");
* traceString fmt2 = xTraceRegisterString("X: %d, Y: %d");
* traceUBChannel UBCh2 = xTraceRegisterUBChannel(chn2, fmt2);
*
* // Result in "[Channel 1] Event!"
* vTraceUBEvent(UBCh1);
*
* // Result in "[Channel 2] X: 23, Y: 19"
* vTraceUBData(UBCh2, 23, 19);
*
* You can also use the other user event functions, like vTracePrintF.
* as they are then rerouted to the UB instead of the main event buffer.
* vTracePrintF then looks up the correct UB channel based on the
* provided channel name and format string, or creates a new UB channel
* if no match is found. The format string should therefore not contain
* "random" messages but mainly format specifiers. Random strings should
* be stored using %s and with the string as an argument.
*
* // Creates a new UB channel ("Channel 2", "%Z: %d")
* vTracePrintF(chn2, "%Z: %d", value1);
*
* // Finds the existing UB channel
* vTracePrintF(chn2, "%Z: %d", value2);

Tracealyzer - Uploading the trace data
-----------------------------------------
Percepio AB, Jan. 23, 2014
This document decribes how to upload the trace data from the target system to
Tracealyzer.
Tracealyzer uses your existing debugger to upload the trace data from the
chip RAM. This is a plain RAM dump, that is done whenever you want to look at
the trace buffer contents. This means it works with essentially with any debug
probe on the market.
Built-in support for Segger J-Link/J-Trace and Atmel SAM-ICE
------------------------------------------------------------
Tracealyzer v2.3 supports Segger J-Link and J-Link compatible debuggers
directly, without any debugger IDE involved. Using other debug probes is
also possible, but requires some extra steps, described below.
If you have a Segger J-Link/J-Trace debug probe or another J-Link compatible
debug probe, just select "Read Trace" in the "J-Link" menu. Note that this
menu is only available if a compatible debug probe is found.
This opens a dialog where you get to enter the memory region where
the recorder data structure is located. Normally you select the entire
internal RAM according to the datasheet of your MCU, but the exact address
can be found can by inspecting the "RecorderData" struct or the
"RecorderDataPtr" pointer with your debugger.
J-Link compatible debug probes also include Atmel SAM-ICE and many built-in
debug interfaces on demonstration/evaluation boards (where there is a USB
connection directly to the board). Look for a Segger J-Link label on the board.
MemoryLogger extension in Atmel Studio 6
----------------------------------------
Atmel's MemoryLogger extension provides a superb integration with FreeRTOS+Trace.
Look for "MemoryLogger" in Atmel Gallery, available in Atmel Studio and at the
Atmel website (http://gallery.atmel.com).
This extension automatically detects the path to FreeRTOS+Trace, if
installed, and gives you a single-click upload/refresh. You can use it
while debugging and optionally get an automatic refresh eash time the
MCU is halted, e.g., on each breakpoint.
Using other development environments and debug probes
-----------------------------------------------------
Most debuggers are able to save the RAM contents to a file. Tracealyzer
supports the following common formats:
- Binary (.bin), supporting gdb, J-Link and Renesas HEW.
- Intel Hex (.hex), supporting IAR Embedded Workbench and Atmel Studio (atprogram.exe)
- MCH (.mch), supporting Microchip MPLAB.
When you store the RAM dump, you must also make sure to select the right region,
i.e., start address and size. The recorder data is stored in a single data
block, identified by the pointer RecorderDataPtr.
It is not necessary to match the begin and end of the recorder data, as long as
it is fully included by the dumped memory region. Tracealyzer automatically
finds the trace data in the RAM dump, thanks to special signatures. For chips
with on-chip RAM only, we therefore recommend to dump the entire RAM. This is
usually very fast.
For chips with larger amounts of (external) RAM, it is typically possible to
dump a limited region where the data is typically found.
Using IAR Embedded Workbench for ARM, version 6.3
-------------------------------------------------
In the debugger view, when stopped on a breakpoint:
- Select "Debug" menu, "Memory" submenu, "Save..." (keyboard shortcut: ALT,d,y,s)
- In the Save dialog
- Zone: Memory
- Start Adress: 10000000 (for NXP LPC1766 in the demo project)
- End Adress: 1000FFFF (for NXP LPC1766 in the demo project)
- File format: Intel Extended
- Filename: <name>.hex
- Press "Save" button
You can now open <name>.hex in Tracealyzer.
To find the right Start and End addresses, check the address of the symbol
"RecorderData". The addresses does not need to match this symbol exactly, as
long as the whole data is included.
Using Renesas High-performance Embedded Workshop v4.09
------------------------------------------------------
In the debugger view, when stopped on a breakpoint:
- Select "Debug" menu, "Save Memory..." (keyboard shortcut: ALT,d,a)
- In the Save dialog
- Format: Binary
- Filename: <name>.bin
- Start Address: 00000000 (For RX62N in the demo project)
- End Address: 0000FFFF (For RX62N in the demo project)
- Access size: 1
- Press "Save" button and open <name>.bin in Tracealyzer.
Using Microchip MPLAB v8.86
------------------------------------------------------
- Select "View" -> "File Registers". This shows you the memory contents.
- Make sure "Hex" is selected in the bottom left (instead of "Symbolic"). Hex mode seems to be default.
- Right click in the view and select "Export Table...".
- In the dialog ("Export As"), make sure "Single Column Output" is selected (seems to be default).
- Select start address 0x0000 and make sure the end address is beyond the RecorderData structure.
The default values seems to be the whole RAM, so you probably don't need to change this.
- Save as a .mch file and open this file in Tracealyzer v2.2.4 or later (support for the .mch format was added in v2.2.4).
Using STM32 ST-Link
------------------------------------------------------
- Start "ST-Link Utility"
- Connect to the device and view the device memory.
- Set the view to display the entire RAM, or at least the section containing the RecorderData structure.
- Select "Save as" and choose binary (.bin) or Intel Hex (.hex) format.
- Open the resulting file in Tracealyzer.

-------------------------------------------------------------------------------
Changes, v3.1.1 -> v3.1.2
- Fixed two bugs related to User Events, one in vTracePrintF and other in vTracePrint.
- Fixed a build problem related to a single reference of the old FreeRTOS type "xTaskHandle", in trcKernelPort.c.
Changed to "TaskHandle_t", unless if using an older FreeRTOS kernel or the "compatibility mode".
- Removed traceCREATE_MUTEX hook for FreeRTOS v9 or later (no longer required)
- Updated the User Manual regarding snapshot trace via IAR Embedded Workbench.
- Renamed vTraceGetTraceBuffer to xTraceGetTraceBuffer, since returning a pointer.
-------------------------------------------------------------------------------
Changes, v3.1.0 -> v3.1.1
After the major changes in the v3.1.0 trace recorder library, this update
corrects a number of minor issues. Only minor functional improvements.
- You can now use TRC_ALLOC_CUSTOM_BUFFER to declare a trace buffer on a custom
location (using linker directives).
The related function vTraceSetRecorderDataBuffer has been promoted to the
Common API (previously only supported in snapshot mode, but custom allocation
is now generally supported also in streaming mode).
- Removed TRC_CFG_USE_LINKER_PRAGMA. No longer necessary thanks to the custom
allocation mode.
- Added support for timestamping from custom periodic timers, required for
accurate timestamping on Cortex-M0/M0+ devices when using tickless idle.
Only for streaming mode so far. See TRC_CUSTOM_TIMER_INCR / DECR.
- ARM Cortex-M port: Made sure the DWT unit is initialized properly, in case
the debugger doesn't handle this.
- ARM Cortex-M port: Added possibility to use Systick timestamping also on
Cortex-M3/M4/M7 devices (that otherwise use DWT timestamping by default).
To use this option, define the macro TRC_CFG_ARM_CM_USE_SYSTICK.
- J-Link streaming: The default RTT buffer has been changed from 0 to 1.
- J-Link streaming: The RTT buffer settings for buffer 1 and higher, are now
found in trcStreamingPort.h. Note: These settings don't apply to buffer 0.
- vTracePrint has been optimized for better performance in string logging.
- Minor performance improvement related to symbol table transfer in streaming mode.
- Timer names now registered also in streaming mode.
- Timer start and stop event are now traced.
- Implemented support for queue registry (traceQUEUE_REGISTRY_ADD) also for streaming.
- Fixed a bug related to repeated calls of vTraceEnable.
- Fixed a bug where task-switches seemed to occur even though the scheduler was disabled.
- Renamed HARDWARE_PORT_TEXAS_INSTRUMENTS_TMS570_RM48, added prefix TRC.
- Fixed several language issues in the comments and documentation.
- Fixed several minor issues and warnings from different compilers
(including PowerPC/gcc) and configurations.
-------------------------------------------------------------------------------
Changes, v3.0.9 -> v3.1.0
- Merge of previously separated snapshot and streaming recorders into a single
recorder supporting both streaming and snapshot as different modes.
- New common API for supporting both streaming and snapshot modes.
- New integration guide, see the User Manual.
- Major improvement of API documentation in source files and User Manual.
- New concept of "stream ports", giving a better structure defining streaming
interfaces, and restructured the J-Link and TCP/IP streaming as stream ports.
- Added a stream port for USB CDC connections, with STM32 as example.
Since Tracealyzer now can receive serial data on Windows COM ports, this is
really easy to use.
- Added a warning (#error) for cases where FreeRTOS tickless idle mode is used
together with timestamping using SysTick or other periodic interrupt timers,
Tracing with tickless idle requires an independent time source to correctly
capture the length of the idle periods.
- Major changes in the recorder API. Important examples are:
* Some configuration macros have changed names, e.g. for "hardware port".
Make sure to remove any old "trcConfig.h" files if upgrading from an
earlier version!
* Recorder configuration in trcConfig.h has been minimized and now only
includes the important settings that are independent of recorder mode.
Advanced settings for each mode are found in trcSnapshotConfig.h and
trcStreamingConfig.h.
* vTraceEnable replaces Trace_Init and vTraceInitTraceData, as well as
vTraceStart and uiTraceStart.
* vTraceStop now part of the common API and thereby available also in
streaming. And since vTraceEnable can start the streaming directly
you have the option control the tracing from target, e.g., for
streaming to a device file system.
* vTraceStoreKernelObjectName from old streaming recorder has been replaced
by vTraceSetQueueName, vTraceSetSemaphoreName, etc.
* vTraceSetISRProperties now returns a "traceHandle" that should be passed as
parameter to vTraceStoreISRBegin and vTraceStoreISREnd.
* xTraceRegisterString has replaced the old functions xTraceOpenLabel and
vTraceStoreUserEventChannelName. This now returns a "traceString" for use
as "channel" parameter in vTracePrintF, and in other places where strings
are stored.
* Removed vTraceStoreISREndManual and vTraceStoreISREndAuto, use
vTraceStoreISREnd instead.
* Renamed the functions for saving User Events in a separate buffer:
- xTraceRegisterChannelFormat -> xTraceRegisterUBChannel
- vTraceChannelPrintF -> vTraceUBData
- vTraceChannelUserEvent -> vTraceUBEvent

Tracealyzer Stream Port for SEGGER J-Link
-----------------------------------------
This directory contains a "stream port" for the Tracealyzer recorder library,
i.e., the specific code needed to use a particular interface for streaming a
Tracealyzer RTOS trace. The stream port is defined by a set of macros in
trcStreamingPort.h, found in the "include" directory.
This particular stream port targets SEGGER J-Link debug probes, using the RTT
interface provided by SEGGER.
To use this stream port, make sure that include/trcStreamingPort.h is found
by the compiler (i.e., add this folder to your project's include paths) and
add all included source files to your build. Make sure no other versions of
trcStreamingPort.h are included by mistake!
Note that this stream port also contains SEGGER's RTT driver.

Tracealyzer Stream Port for TCP/IP (lwIP example)
-------------------------------------------------
This directory contains a "stream port" for the Tracealyzer recorder library,
i.e., the specific code needed to use a particular interface for streaming a
Tracealyzer RTOS trace. The stream port is defined by a set of macros in
trcStreamingPort.h, found in the "include" directory.
This particular stream port targets TCP/IP. This example assumes lwIP but is
easy to modify for other TCP/IP stacks.
To use this stream port, make sure that include/trcStreamingPort.h is found
by the compiler (i.e., add this folder to your project's include paths) and
add all included source files to your build. Make sure no other versions of
trcStreamingPort.h are included by mistake!
Note that lwIP is not included, but assumed to exist in the project already.

Tracealyzer Stream Port for USB CDC (STM32 example)
---------------------------------------------------
This directory contains a "stream port" for the Tracealyzer recorder library,
i.e., the specific code needed to use a particular interface for streaming a
Tracealyzer RTOS trace. The stream port is defined by a set of macros in
trcStreamingPort.h, found in the "include" directory.
This particular stream port targets USB CDC. This is an example for the STM32 USB
stack (from the STM32CubeMX code generation tool, v1.4.1) and has been tested on
a STM32F767ZI device on a Nucleo board. See this blog post:
http://percepio.com/2017/02/03/usb-trace-streaming-st-nucleo-f767zi-board/
However, it should be straight-forward to modify this for other USB stacks.
To use this stream port, make sure that include/trcStreamingPort.h is found
by the compiler (i.e., add this folder to your project's include paths) and
add all included source files to your build. Make sure no other versions of
trcStreamingPort.h are included by mistake!
Note that the USB stack not included, but assumed to exist in the project already.

* On the NXP LPC17xx you may use the secondary RAM bank (AHB RAM) for this

* This of course works for other hardware architectures with additional RAM
* banks as well, just replace "AHB_RAM_MEMORY" with the section name from the
* linker .map file, or simply the desired address.
*
* For portability reasons, we don't add the pragma directly in trcBase.c, but
* in a header file included below. To include this header, you need to enable
* USE_LINKER_PRAGMA, defined in trcConfig.h.

* handle is needed, e.g., on task creation, the next free handle is popped from
* the stack. When an object (e.g., task) is deleted, its handle is pushed back
* on the stack and can thereby be reused for other objects.
*
* Since this allows for reuse of object handles, a specific handle (e.g, "8")
* may refer to TASK_X at one point, and later mean "TASK_Y". To resolve this,
* the recorder uses "Close events", which are stored in the main event buffer
* when objects are deleted and their handles are released. The close event
* contains the mapping between object handle and object name which was valid up
* to this point in time. The object name is stored as a symbol table entry.

The below error message is to alert you on the following issue:
The hardware port selected in trcConfig.h uses the operating system timer for the
timestamping, i.e., the periodic interrupt timer that drives the OS tick interrupt.
When using tickless idle, the recorder needs an independent time source in order to
correctly record the durations of the idle times. Otherwise, the trace may appear
to have a different length than in reality, and the reported CPU load is also affected.
You may override this warning by defining the TRC_CFG_ACKNOWLEDGE_TICKLESS_IDLE_WARNING
macro in your trcConfig.h file. But then the time scale may be incorrect during
tickless idle periods.
#include <stdint.h>
To get this correct, override the default timestamping by setting TRC_CFG_HARDWARE_PORT
in trcConfig.h to TRC_HARDWARE_PORT_APPLICATION_DEFINED and define the HWTC macros
