& & &&在调用任务创建函数xTaskCreate()时就为任务指定了优先级，在启动了任务调度函数之后，可以通过调用xTaskPrioritySet()函数来修改任务的优先级。&br /&
& & &系统中理论上没有对优先级做出上限要求，只要内存足够大就可以创建多个任务，设置不同的优先级，不同的任务可以赋予相同的优先级，在FreeRTOSConfig.h中configMAX_PRIORITIES 的大小决定最大优先级个数，优先级是从0开始到configMAX_PRIORITIES - 1为止，优先级为0的任务的优先级最高。&br style=&line-height:orphans:2;text-align:-webkit-white-space:widows:2;& /&
& & &系统中的调度器总是先让优先级最高的任务先运行，如果多个任务拥有相同的优先级，那么调度器将会使得任务轮流执行一个时间片。这里的时间片等于1/心跳时钟频率，心跳时钟即滴答时钟。可以通过设置&span style=&white-space:&&FreeRTOSConfig.h中的configTICK_RATE_HZ来设置心跳中断时钟，当&span style=&white-space:&&configTICK_RATE_HZ赋值为100HZ时，每100模式发生一次心跳时钟中断，系统会执行相应的中断函数。&br /&
& & 对于不同优先级的任务，调度器总是先让优先级高的任务运行，下面用一个例子说明。&br /&

CC3200 跑FreeRTOS 多任务时失败
发表于7月前
<input type="hidden" id="hGroupID" value="44"
我在&a href=&.cn/product/cn/CC3200& target=&extwin&>CC3200&/a> 里面使用osi_TaskCreate 创建了6个任务，每个任务的STACK_SIZE设置为2048， 有一个任务的优先级最高，其余5个优先级相同比第一个要低，初始运行时有一个任务用来监听外部socket 的消息，其余5个任务都在while循环里等待自己队列的消息， 当程序启动，运行这个几个任务时，发现系统hang住了，请问出现这种情况的原因是因为系统分配的资源不够么？如果是的话要怎么样扩展task 运行时的任务占用的资源呢？如果不是 ，那可能是什么原因呢？有办法能避免么？ 图片是我的工程里面设置的size&/p>

会不会是多个任务同时写入同一个资源了，你查一下是挂死在哪儿了呢？

我加大了heap size 就好了

那就是使用了Malloc函数导致Heap分配不足，同时注意由于没有MPU的对内存的保护，程序中注意最大内存分配和最大可连续地址内存分配。
