how to run some codes before tasks?

Hi Richard, thanks a lot.

Now only 3rd question left.
I add :
portBASE_TYPE xReturn;
  xReturn=xTaskCreate( vT1, (signed char *) “TIME”, configMINIMAL_STACK_SIZE,
            NULL, mainTIME_TASK_PRIORITY, &hTimeTask );
……Same to vT6

Total 6 tasks. If I mark any one task, all runs well.
If 6 tasks, none of them runs. Their return codes are “pdPASS”

How do I change the heap space? My MCU is STM32F407V.  I am very new at FreeRTOS. I can not even understand the document you give me above. Appreciate very much if you could prove more detail or sample codes.
