CortexR4: Spurious Data Abort Interrupt

Kernel
16

Please add the following to mpu_wrappers.c:

#if( configSUPPORT_DYNAMIC_ALLOCATION == 1 )

	void *MPU_pvPortMalloc( size_t xSize )
	{
	void *pvReturn;
	BaseType_t xRunningPrivileged = prvRaisePrivilege();

		pvReturn = pvPortMalloc( xSize );

		vPortResetPrivilege( xRunningPrivileged );

		return pvReturn;
	}

#endif /* configSUPPORT_DYNAMIC_ALLOCATION */
/*-----------------------------------------------------------*/

#if( configSUPPORT_DYNAMIC_ALLOCATION == 1 )

	void MPU_vPortFree( void *pv )
	{
	BaseType_t xRunningPrivileged = prvRaisePrivilege();

		vPortFree( pv );

		vPortResetPrivilege( xRunningPrivileged );
	}

#endif /* configSUPPORT_DYNAMIC_ALLOCATION */
/*-----------------------------------------------------------*/

And the following to mpu_wrappers.h:

#define pvPortMalloc   MPU_pvPortMalloc
#define vPortFree      MPU_vPortFree

Give it a try and see if it fixes your issue.
