/* *** NOTE ***********************************************************
If you find your application is crashing here then likely causes are
listed below. In addition see http://www.freertos.org/FAQHelp.html for
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?).

如果没有出现 上述问题，请检查是否硬件堆栈分配。因为新建立的任务会消耗一部分硬件栈空间
另外开启任务堆栈监测是非常重要的，可以仔细的调整一下，有的任务分配的多，有的任务分配的少
另外 注意观察优先级配置，优先级config.h中的
要和你freertos系统时钟中断优先级对应，不能搞不能低
