Description

Function Documentation

void EvrRtxMutexError ( osMutexId_t  mutex_id,
int32_t  status 
)
Parameters
[in]mutex_idmutex ID obtained by osMutexNew or NULL when ID is unknown.
[in]statusextended execution status.

The event MutexError is generated when Mutex Management routines complete their execution due to an error.

The status parameter indicates the execution status and can be one of the osStatus_t codes or one of the extended execution status codes which are summarized in the table below.

Extended Status Code Description
osRtxErrorKernelNotReady Kernel scheduler is not in Ready state.
osRtxErrorKernelNotRunning Kernel scheduler is not executing - there is no running thread.
osRtxErrorInvalidControlBlock Object control block with invalid alignment or size was specified.
osRtxErrorInvalidDataMemory Object data memory with invalid alignment or size was specified.
osRtxErrorInvalidThreadStack Thread stack memory with invalid alignment or size was specified.
osRtxErrorInvalidPriority Invalid thread priority was specified.
osRtxErrorThreadNotJoinable Specified thread is not joinable.
osRtxErrorMutexNotOwned Specified mutex is not owned by the current running thread.
osRtxErrorMutexNotLocked Specified mutex is not locked.
osRtxErrorMutexLockLimit Maximum number of recursive mutex locks reached.
osRtxErrorSemaphoreCountLimit Semaphore count limit reached.
osRtxErrorTZ_InitContext_S Secure context memory system initialization failed.
osRtxErrorTZ_AllocContext_S Secure context memory allocation failed.
osRtxErrorTZ_FreeContext_S Secure context memory deallocation failed.
osRtxErrorTZ_LoadContext_S Secure context load failed.
osRtxErrorTZ_SaveContext_S Secure context save failed.

Value in the Event Recorder shows:

  • mutex_id : mutex ID.
  • status : execution status code.
void EvrRtxMutexNew ( const osMutexAttr_t *  attr)
Parameters
[in]attrmutex attributes

The event MutexNew is generated when the function osMutexNew is called.

Value in the Event Recorder shows:

  • attr : memory address of Mutex attributes or 0 when they are not specified.

In case when mutex attributes are provided in the API call they are also detailed in the Event Recorder.

void EvrRtxMutexCreated ( osMutexId_t  mutex_id)
Parameters
[in]mutex_idmutex ID obtained by osMutexNew.

The event MutexCreated is generated when the function osMutexNew successfully creates a mutex object.

Value in the Event Recorder shows:

  • mutex_id : mutex ID.
void EvrRtxMutexGetName ( osMutexId_t  mutex_id,
const char *  name 
)
Parameters
[in]mutex_idmutex ID obtained by osMutexNew.
[in]namepointer to mutex object name

The event MutexGetName is generated when the function osMutexGetName is called and its execution result is known.

Value in the Event Recorder shows:

  • mutex_id : mutex ID.
  • name : retrieved memory address of name string (0 in case of a failure).
void EvrRtxMutexAcquire ( osMutexId_t  mutex_id,
uint32_t  timeout 
)
Parameters
[in]mutex_idmutex ID obtained by osMutexNew.
[in]timeoutTimeout Value or 0 in case of no time-out.

The event MutexAcquire is generated when the function osMutexAcquire is called.

Value in the Event Recorder shows:

void EvrRtxMutexAcquirePending ( osMutexId_t  mutex_id,
uint32_t  timeout 
)
Parameters
[in]mutex_idmutex ID obtained by osMutexNew.
[in]timeoutTimeout Value or 0 in case of no time-out.

The event MutexAcquirePending is generated when the function osMutexAcquire blocks current running thread and waits for mutex to become available.

Value in the Event Recorder shows:

void EvrRtxMutexAcquireTimeout ( osMutexId_t  mutex_id)
Parameters
[in]mutex_idmutex ID obtained by osMutexNew.

The event MutexAcquireTimeout is generated when wait for mutex to become available is aborted due to expired wait timeout.

Value in the Event Recorder shows:

  • mutex_id : mutex ID.
void EvrRtxMutexAcquired ( osMutexId_t  mutex_id,
uint32_t  lock 
)
Parameters
[in]mutex_idmutex ID obtained by osMutexNew.
[in]lockcurrent number of times mutex object is locked

The event MutexAcquired is generated when the function osMutexAcquire successfully acquires a mutex.

Value in the Event Recorder shows:

  • mutex_id : mutex ID.
  • lock : current lock counter state.
void EvrRtxMutexNotAcquired ( osMutexId_t  mutex_id)
Parameters
[in]mutex_idmutex ID obtained by osMutexNew.

The event MutexNotAcquired is generated when the function osMutexAcquire returns without timeout and mutex was not acquired.

Value in the Event Recorder shows:

  • mutex_id : mutex ID.
void EvrRtxMutexRelease ( osMutexId_t  mutex_id)
Parameters
[in]mutex_idmutex ID obtained by osMutexNew.

The event MutexRelease is generated when the function osMutexRelease is called.

Value in the Event Recorder shows:

  • mutex_id : mutex ID.
void EvrRtxMutexReleased ( osMutexId_t  mutex_id,
uint32_t  lock 
)
Parameters
[in]mutex_idmutex ID obtained by osMutexNew.
[in]lockcurrent number of times mutex object is locked

The event MutexReleased is generated when the function osMutexRelease successfully releases a mutex.

Value in the Event Recorder shows:

  • mutex_id : mutex ID.
  • lock : current lock counter state.
void EvrRtxMutexGetOwner ( osMutexId_t  mutex_id,
osThreadId_t  thread_id 
)
Parameters
[in]mutex_idmutex ID obtained by osMutexNew.
[in]thread_idthread ID obtained by osThreadNew or osThreadGetId.

The event MutexGetOwner is generated when the function osMutexGetOwner is called and its execution result is known.

Value in the Event Recorder shows:

  • mutex_id : mutex ID.
  • thread_id : retrieved owner thread ID (0 in case of a failure or when mutex is not locked)
