Description

Function Documentation

void EvrRtxKernelError

(

int32_t

status

)

Parameters

[in]

status

extended execution status.

The event KernelError is generated when Kernel Information and Control 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:

• status : execution status code.
