/* *** NOTE ***********************************************************
If you find your application is crashing here then likely causes are:
1) Stack overflow -
see http://www.freertos.org/Stacks-and-stack-overflow-checking.html
2) Incorrect interrupt priority assignment, especially on Cortex M3
parts where numerically high priority values denote low actual
interrupt priories, which can seem counter intuitive. See
configMAX_SYSCALL_INTERRUPT_PRIORITY on http://www.freertos.org/a00110.html
3) Calling an API function from within a critical section or when
the scheduler is suspended.
4) Using a queue or semaphore before it has been initialised or
before the scheduler has been started (are interrupts firing
before vTaskStartScheduler() has been called?).
See http://www.freertos.org/FAQHelp.html for more tips.
