If you find your application is crashing here then likely causes are

more tips, and ensure configASSERT() is defined!
|

http://www.freertos.org/a00110.html#configASSERT
|

|

1) Stack overflow -
|
||||
see http://www.freertos.org/Stacks-and-stack-overflow-checking.html
|
||||
2) Incorrect interrupt priority assignment, especially on Cortex-M
|
||||
parts where numerically high priority values denote low actual
|
||||
interrupt priorities, which can seem counter intuitive. See
|
||||
http://www.freertos.org/RTOS-Cortex-M3-M4.html and the definition
|
||||
of 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, or calling an API function that does
|
||||
not end in "FromISR" from an interrupt.
|
||||
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?).
