Hi,
i'm trying to create a message buffer between two tasks one is on core0 of the MPC5777C and the other one on the other core, the first task basically will send to the buffer and the other task will receive from the buffer.
when i do the implementation it works fine but only while debugging, but at runtime it doesn't work, i tried to attach to running reset to see why it stops and it seems it stops in one of the memset functions (that function is called from the function prvInitialiseNewStreamBuffer which in turns is called from the
xStreamBufferGenericCreateStatic function)
static void prvInitialiseNewStreamBuffer( StreamBuffer_t * const pxStreamBuffer,
uint8_t * const pucBuffer,
size_t xBufferSizeBytes,
size_t xTriggerLevelBytes,
uint8_t ucFlags )
{
/* Assert here is deliberately writing to the entire buffer to ensure it can
* be written to without generating exceptions, and is setting the buffer to a
* known value to assist in development/debugging. */
#if ( configASSERT_DEFINED == 1 )
{
/* The value written just has to be identifiable when looking at the
* memory. Don't use 0xA5 as that is the stack fill value and could
* result in confusion as to what is actually being observed. */
const BaseType_t xWriteValue = 0x55;
configASSERT( memset( pucBuffer, ( int ) xWriteValue, xBufferSizeBytes ) == pucBuffer );
} /*lint !e529 !e438 xWriteValue is only used if configASSERT() is defined. */
#endif
( void ) memset( ( void * ) pxStreamBuffer, 0x00, sizeof( StreamBuffer_t ) ); /*lint !e9087 memset() requires void *. */
pxStreamBuffer->pucBuffer = pucBuffer;
pxStreamBuffer->xLength = xBufferSizeBytes;
pxStreamBuffer->xTriggerLevelBytes = xTriggerLevelBytes;
pxStreamBuffer->ucFlags = ucFlags;
}
