+ * Percepio AB, www.percepio.com
+ *
+ * trcExtensions.h
+ *
+ * The extension interface of the recorder library, allowing for tracing
+ * function calls to any API without modifications. All that is needed is a
+ * single #include line in the .c files calling the API.
+ *
+ * This can be used to provide more detailed traces, including calls to e.g.
+ * middleware, drivers or important APIs in your application code. This can be
+ * applied selectively to specified functions and may include selected
+ * parameters as well as the return value.
+ *
+ * Unlike the "User Event" concept, an extension is intended for systematic use
+ * and can benefit from all powerful features in Tracealyzer via host-side XML
+ * files that configure how Tracealyzer should interpret each event.
+ *
+ * Extensions are self-contained and easy to integrate, which makes them
+ * convenient for distribution. Software vendors can thus develop such
+ * extensions and provide trace support for their users.
+ *
+ * An extension consists of two files:
+ *
+ *  - An extension header file (e.g. "api.tzext.h") - this defines how to
+ *  trace the API function calls.
+ *
+ *  - An XML file for the Tracealyzer application (e.g. "api-v1.0.0.xml").
+ *  This needs to match the tracing setup in your extension header file.
+ *
+ *
+ * USAGE
+ *
+ * This description assumes you already have the extension files for the APIs you
+ * like to trace. To include them, follow these steps:
+ *
+ * 1. Update trcExtensions.h with respect to:
+ *
+ *    1.1. TRC_CFG_EXTENSION_COUNT: The number of extensions to enable (max 4).
+ *
+ *    1.2. The name(s) of the extension header file(s) to include.
+ *
+ *    1.3. The Extension Prefix, i.e., the first part of the definition names
+ *         used in each header file.
+ *
+ * 2. Add #include "trcExtensions.h" in all .c files calling the API:
+ *
+ *    #include ...
+ *    #include "api.h"  // The API you like to trace
+ *    #include ...
+ *    #include "trcExtensions.h"
+ *
+ *    We recommend to put this as the LAST #include statement.
+ *
+ *    HOWEVER, don't include "trcExtensions.h" in the .c files containing the
+ *    functions you intend to trace. The compiler will then complain about
+ *    multiple definitions of the trace wrapper function.
+ *
+ * 3. Copy the extension XML file to the "Tracealyzer 4/cfg" folder.
+ *    On Windows this is typically
+ *
+ *    C:\Program Files\Percepio\Tracealyzer 4\cfg
+ *
+ *
+ * HOW IT WORKS
+ *
+ * By including "trcExtensions.h" in your .c files, the preprocessor will
+ * redefine all calls of the functions specified in the extension header file.
+ * Calls to those functions will now instead call the "trace wrapper functions"
+ * defined in the extension header. The trace wrapper functions then call the
+ * original function as well as the trace recorder library.
+ *
+ * call foo(a) ----> foo__trace(a) -----> foo(a)
+ *                                 -----> trace recorder library
+ *
+ * Note that the trace wrapper function should have the same declaration as the
+ * original function (apart from the name) and also returns any return value
+ * back to the original caller. So functionally this is completely transparent.
+ *
+ * This works also for calls via function pointers, as the assignments of the
+ * function pointers will be affected, so the function pointers will point to
+ * the trace wrapper function.
+ *
+ * It even works when calling binary libraries, since only the calling code
+ * is modified, not the API itself.
+ *
+ * Extensions include a version code (Major.Minor.Patch), which is registered
+ * in the trace and also part of the XML file name. This way, Tracealyzer
+ * automatically finds the matching XML file, even if you open a old trace
+ * recorded using a earlier version of the extension (e.g. if the API has
+ * changed).
+ *
+ * LIMITATIONS
+ *
+ * The main limitation of this automatic approach is that it only allows for
+ * tracing call between different .c files. Moreover, you can't trace multiple
+ * APIs with calls between them. This since the calling file must include
+ * trcExtensions.h, while the called file must NOT include this.
+ *
+ * It is however possible to get around this limitation. You need to add
+ * #undef lines for each affected function to locally disable the redefinition,
+ * and modify each function call to instead call the trace wrapper function.
+ *
+ *   #include "trcExtensions.h"
+ *   #undef foo
+ *   ...
+ *   void foo(int a)
+ *   {
+ *     ...
+ *   }
+ *   ...
+ *   foo__trace(a); // in another function - call foo and trace it
+ *
+ * These changes can remain in your code if you like, as the trace wrappers
+ * works even if the recorder is disabled.
+ *
+ * MAKING YOUR OWN EXTENSIONS
+ *
+ * Examples are found in the extensions directory. We recommend that you start
+ * by looking at aws_secure_sockets files (.h and .xml) that provides a basic
+ * example. The aws_wifi files provides a more advanced example.
+ * The header files include detailed documentation about how to design them,
+ *
+ * The XML files should have the same name as specified in the NAME property
+ * in the header file, followed by the version, i.e.
+ *
+ * <NAME>-v<VERSION_MAJOR>.<<VERSION_MINOR>.<VERSION_PATCH>.xml
+ *
+ * Documentation for the XML file format is not yet available, but is under
+ * development.

-          Tracealyzer for FreeRTOS - Trace Recorder Library v3.1.1                      
--------------------------------------------------------------------------------
-
-Tracealyzer for FreeRTOS is a sophisticated tool for tracing and visualization
-of FreeRTOS-based systems. Tracealyzer gives an unprecedented insight into the
-runtime behavior, which speeds up debugging, validation and optimization. 
-
-To learn more about this, see
-
- - Getting Started (videos etc): http://percepio.com/gettingstarted/tz-freertos/
-
- - User Manual (incl. Recorder API): http://percepio.com/docs/FreeRTOS/manual
-
- - FAQ: http://percepio.com/category/faq/
-
-In case you have any questions, don't hesitate to contact support@percepio.com
-
--------------------------------------------------------------------------------
-
-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 Amazon FreeRTOS TCP/WIFI
+----------------------------------------------------
+
+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 is for streaming via a TCP socket in Amazon
+FreeRTOS (AFR) directly to a host computer on the local network, typically 
+using Wifi. Read more in trcStreamingPort.h.
+
+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!

+/*******************************************************************************
+ * Trace Recorder Library for Tracealyzer v4.3.11
+ * Percepio AB, www.percepio.com
+ *
+ * trcStreamingPort.c
+ *
+ * This stream port provides trace streaming using the Amazon FreeRTOS sockets
+ * layer and is intended for streaming over Wifi directly to a computer on the
+ * local Wifi network. 
+ *
+ * Note that this does NOT use the TLS encryption available in Amazon
+ * FreeRTOS, due to performance and memory usage concerns. However, it does not
+ * use any AWS services either, and is intended for your local network only.
+ *
+ * This should be started using vTraceEnable(TRC_START) and this call should be
+ * made AFTER the kernel has started and the Wifi interface is ready.
+ *
+ * In the Tracealyzer setting -> "PSF Streaming Settings" make sure that the
+ * "Target Connection" setting is "TCP (Target Initiated)".
+ *
+ * To use this, make sure to start the trace recording in Tracealyzer before
+ * you start your target system. This ensures that Tracealyzer is ready when
+ * the target system connects.
+ *
+ * And don't forget to enter the IP address of the Tracealyzer host computer
+ * in trcStreamingPort.h.
+ *
+ * NOTES:
+ *
+ * 1: The tracing will increase the stack usage of you application, so you
+ * may want to increase configMINIMAL_STACK_SIZE in your FreeRTOSConfig.h.
+ *
+ * 2: To reduce the amount of trace data, we recommend disabling the tracing
+ * of OS Ticks and memory allocation events.
+ * See TRC_CFG_INCLUDE_OSTICK_EVENTS in trcConfig.h.
+ *
+ * 3: The transmission of trace data is done in the TzCtrl task. To avoid that
+ * the trace streaming is blocked during the (long) MQTT connection phase,
+ * make sure the scheduling priority of TzCtrl is higher than the MQTT task.
+ * Otherwise, if you prefer to run the TzCtrl task at lower priority to avoid
+ * interfering with your application, wait with the vTraceEnable call until
+ * after the MQTT connection is established.
+ * See TRC_CFG_CTRL_TASK_PRIORITY in trcStreamingConfig.h.
+ *
+ * 4: The Wifi transmission of trace data often uses FreeRTOS functions, that
+ * are traced and thus produce additional trace data. This may cause a fast
+ * increase in trace data rate, that may saturate the trace buffer and cause
+ * data loss (i.e. incomplete traces).
+ * To eliminate this effect and reduce the amount of trace data produced, we
+ * recommend excluding all FreeRTOS objects that are used by Wifi stack.
+ * This is done using vTraceSetFilterGroup and vTraceSetFilterMask:
+ *
+ *   // Just before wifi initialization:
+ *
+ *   // All objects created after this point are assigned to group 15.
+ *   vTraceSetFilterGroup(FilterGroup15);
+ *
+ *   // Only trace objects assigned to group 0 (the default group).
+ *   vTraceSetFilterMask(FilterGroup0);
+ *
+ *   // The wifi stack initialization... (creates semaphores etc.)
+ *   if ( eWifi_Connected == prvWifiConnect() )
+ *   {
+ *       yMainState = eMain_StartApplication;
+ *
+ *       // When connected, restore the FilterGroup setting to Group 0, so
+ *       // that later created objects are included, like the TzCtrl task
+ *       // created in vTraceEnable. Excluding tasks is not recommended!
+ *       vTraceSetFilterGroup(FilterGroup0);
+ *
+ *       // Then call vTraceEnable to start the tracing.
+ *       vTraceEnable(TRC_START);
+ *   }
+ *
+ * 5: If you still get "red sections" in Tracealyzer (lost data), you need
+ * to adjust the other settings in trcStreamingConfig.h.
+ *
+ *   - TRC_CFG_PAGED_EVENT_BUFFER_PAGE_COUNT
+ *     Increase this, as long as you have memory to spare.
+ *
+ *   - TRC_CFG_PAGED_EVENT_BUFFER_PAGE_SIZE
+ *     Increase this, as long as you have memory to spare.
+ *     But don't exceed the maximum payload size of the Wifi chip, which
+ *     is often limited to 1000-1500 bytes. Some chips crash if you try to
+ *     send to large chunks...
+ *
+ *   - TRC_CFG_CTRL_TASK_DELAY
+ *     Decrease this to flush the trace buffer more frequently.
+ *

@@ -9,12 +9,40 @@ 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
+Instructions:
-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.
+1. Integrate the trace recorder and configure it for streaming, as described
+   in the Tracealyzer User Manual. For FreeRTOS this is found at:
+   https://percepio.com/docs/FreeRTOS/manual/index.html#Creating_and_Loading_Traces___Introduction
+
+2. Make sure all .c and .h files from this stream port folder is included in 
+   your build, and that no other variant of trcStreamingPort.h is included.
+
+3. In lwipopts.h, make sure you have this line:
+   
+   #define LWIP_SOCKET 1
+
+4. Make sure that vTraceEnable(TRC_INIT) is called during the startup, before
+   any RTOS calls are made.
+
+5. In Tracealyzer, open File -> Settings -> PSF Streaming Settings and
+   select Target Connection: TCP. Enter the IP address of the target system
+   and the port number (by default 12000).
+
+6. Start your target system, wait a few seconds to ensure that the lwIP is operational, 
+   then select Start Recording in Tracealyzer.
+
+Troubleshooting:
+
+- If the tracing suddenly stops, check the "errno" value in trcSocketSend (trcStreamingPort.c).
+You can see the error code definitions in lwip/errno.h. If errno is ENOMEM, may you need to 
+increase MEM_SIZE in lwipopts.h.
+
+- Since lwIP performs a lot of semaphore and mutex operations, we recommend filtering out 
+such events from the trace, at least those caused by the transmission of trace data in the
+TzCtrl task. This can be done using vTraceSetFilterGroup() and vTraceSetFilterMask().
+
+Note that lwIP is not included in the stream port, but assumed to exist in the project already.

+Tracealyzer Stream Port for TCP/IP (Win32 example)
+-------------------------------------------------
+
+This directory contains a "stream port" for the Tracealyzer recorder library,
+i.e., the I/O code needed for streaming a Tracealyzer RTOS trace over specific
+interface. The stream port is defined by a set of macros in trcStreamingPort.h,
+found in the "include" directory.
+
+This particular stream port is for streaming over TCP/IP on Windows, intended
+for the FreeRTOS Windows port (WIN32-MSVC). To try it:
+
+1. Open the WIN32-MSVC demo project found in the FreeRTOS demo folder. You 
+need will Visual Studio, but there are free versions (Express or Community).
+
+2. Make sure the project includes a recent version or the recorder library
+(v3.1.x).
+
+3. Make sure the recorder library is configured for streaming mode (see
+trcConfig.h).
+
+4. Make sure the project's include paths contains trcStreamingPort.h found in
+this include folder (and not any other stream port), and the related code 
+in this folder.
+
+5. Build and start the Win32 demo application. It should begin waiting for
+a connection. 
+
+6. In Tracealyzer, open File -> Settings... -> Streaming Trace Settings.
+Specify target connection: TCP, host: 127.0.0.1 (i.e. localhost) and port 8888.
+
+7. In Tracealyzer, now open File -> Connect to Target System... and there 
+click "Start Recording". Now you should see a live CPU load graph and some 
+counters. Let it record for a few seconds, then click "Stop Recording" and then "View Trace".
