Hi
Board STM32F469 Discovery, IDE Keil, I am getting Random Hard Faults and the code is getting stuck at while( TransferInProgress ) in the follow code block
void EwBspGraphicsWaitForCompletion()
{
/* return immediately if no DMA2D transfer is ongoing */
if ( TransferInProgress == 0 )
return;
CPU_LOAD_SET_IDLE();
#ifdef EW_USE_DMA2D_INTERRUPT_MODE
#if EW_USE_FREE_RTOS == 1
osSemaphoreWait( AcceleratorSemaphoreId, 1000 );
TransferInProgress = 0;
#else
/* wait until DMA2D transfer is done */
while( TransferInProgress )
;
#endif
#else
/* wait until DMA2D transfer is done */
HAL_DMA2D_PollForTransfer( &Accelerator, 1000 );
TransferInProgress = 0;
#endif
CPU_LOAD_SET_ACTIVE();
}
