* TRACE_DATA_ALLOCATION
|

* static declaration or using a dynamic allocation in runtime (malloc).

*
|

* Should be one of these two options:
|
||||
* - TRACE_DATA_ALLOCATION_STATIC (default)
|
||||
* - TRACE_DATA_ALLOCATION_DYNAMIC
|
||||
*
|
||||
* Using static allocation has the benefits of compile-time errors if the buffer
|
||||
* is too large (too large constants in trcConfig.h) and no need to call the
|
||||
* initialization routine (xTraceInitTraceData).
|
||||
*
|
||||
* Using dynamic allocation may give more flexibility in some cases.

* stored in a ring buffer, i.e., where the oldest events are overwritten when
|
||||
* the buffer becomes full. This allows you to get the last events leading up
|
||||
* to an interesting state, e.g., an error, without having a large trace buffer
|
||||
* for string the whole run since startup. In this mode, the recorder can run
|
||||
* "forever" as the buffer never gets full, i.e., in the sense that it always
|
||||
* has room for more events.
|
||||
*
|
||||
* To fetch the trace in mode TRACE_STORE_MODE_RING_BUFFER, you need to first halt the
|
||||
* system using your debugger and then do a RAM dump, or to explicitly stop the

* recorder using vTraceStop() and then store/upload the trace data using a

|

*
|

|

*

|

*
|

* ### Instance Finish Events (IFE) ###
|
||||
*
|
||||
* For tasks with "infinite" main loops (non-terminating tasks), the concept
|
||||
* of a task instance has no clear definition, it is an application-specific
|
||||
* thing. Tracealyzer allows you to define Instance Finish Events (IFEs),
|
||||
* which marks the point in a cyclic task when the "task instance" ends.
|
||||
* The IFE is a blocking kernel call, typically in the main loop of a task
|
||||
* which typically reads a message queue, waits for a semaphore or performs
|
||||
* an explicit delay.
|
||||
*
|
||||
* If USE_IMPLICIT_IFE_RULES is one (1), the kernel macros (trcKernelPort.h)
|
||||
* will define what kernel calls are considered by default to be IFEs.
|
||||
*
|
||||
* However, Implicit IFEs only applies to blocking kernel calls. If a
|
||||
* service reads a message without blocking, it does not create a new
|
||||
* instance since no blocking occurred.
|
||||
*
|
||||
* Moreover, the actual IFE might sometimes be another blocking call. We
|
||||
* therefore allow for user-defined Explicit IFEs by calling
|
||||
*
|
||||
* vTraceTaskInstanceIsFinished()
|
||||
*
|
||||
* right before the kernel call considered as IFE. This does not create an
|
||||
* additional event but instead stores the service code and object handle
|
||||
* of the IFE call as properties of the task.
|
||||
*
|
||||
* If using Explicit IFEs and the task also calls an Implicit IFE, this may
|
||||
* result in additional incorrect task instances.
|
||||
* This is solved by disabling the Implicit IFEs for the task, by adding
|
||||
* a call to
|
||||
*
|
||||
* vTraceTaskSkipDefaultInstanceFinishedEvents()
|
||||
*
|
||||
* in the very beginning of that task. This allows you to combine Explicit IFEs
|
||||
* for some tasks with Implicit IFEs for the rest of the tasks, if
|
||||
* USE_IMPLICIT_IFE_RULES is 1.
|
||||
*
|
||||
* By setting USE_IMPLICIT_IFE_RULES to zero (0), the implicit IFEs are disabled
|
||||
* for all tasks. Tasks will then be considered to have a single instance only,
|
||||
* covering all execution fragments, unless you define an explicit IFE in each
|
||||
* task by calling vTraceTaskInstanceIsFinished before the blocking call.

|

*
|
||||
* 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.
|
||||
*
|
||||
* 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.
|
||||
*
|
||||
* 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.
|
||||
*
|
||||
* HWTC_PERIOD: The number of increments or decrements of HWTC_COUNT between
|
||||
* two 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).
|
||||
*
|
||||
* 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.
|
||||
*
|
||||
* 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.

*******************************************************************************

|

* main() creates all the demo application tasks, then starts the scheduler.
|

* The web documentation provides more details of the standard demo application
|

* tasks, which provide no particular functionality but do provide a good
|
||||
* example of how to use the FreeRTOS API.
|
||||
*
|
||||
* In addition to the standard demo tasks, the following tasks and tests are
|
||||
* defined and/or created within this file:
|
||||
*
|
||||
* "Check" task - This only executes every five seconds but has a high priority
|
||||
* to ensure it gets processor time. Its main function is to check that all the
|
||||
* standard demo tasks are still operational. While no errors have been
|
||||
* discovered the check task will print out "OK" and the current simulated tick
|
||||
* time. If an error is discovered in the execution of a task then the check
|
||||
* task will print out an appropriate error message.
