[FreeRTOS Home] [Live FreeRTOS Forum] [FAQ] [Archive Top] [January 2006 Threads] How to size the stack processPosted by Nobody/Anonymous on January 23, 2006 hi,
How can understand when the stack of a process is too little? In other words, At run time, how can I understand if the stack is full or near to be full?
Thanks!!
RE: How to size the stack processPosted by Richard on January 23, 2006 The stack is filled with 0xa5 when the task is created. In the debugger you can inspect the stack and see how much remains at 0xa5 which will show you the high water mark.
There is also a function usTaskCheckFreeStackSpace(), although this leaves interrupts disabled for a while and is not good to use in a production system.
The live WEB server demo's use usTaskCheckFreeStackSpace to display the high water mark of each stack.
