timer_thread的rt_thread_timeout执行时，出现断言错误

发布于 2018-06-13 19:01:41 浏览：2713 订阅该版

如题：timer_thread的rt_thread_timeout执行时，出现了RT_ASSERT((thread->stat & RT_THREAD_STAT_MASK) == RT_THREAD_SUSPEND)的断言错误；通过打log的方式发现，rt_timer_start在如下位置被重入，导致被重入的rt_timer_start函数恢复执行时，将timer_thread的状态修改为了ready，而后timer_thread的rt_thread_timeout执行时，就出现了断言错误。

不知分析的对不对，请帮忙分析一下。

rt_err_t rt_timer_start(rt_timer_t timer)

#ifdef RT_USING_TIMER_SOFT
    if (timer->parent.flag & RT_TIMER_FLAG_SOFT_TIMER)
    {
        /* check whether timer thread is ready */
        if ((timer_thread.stat & RT_THREAD_STAT_MASK) != RT_THREAD_READY)
        {
            /* resume timer thread to check soft timer */
            rt_thread_resume(&timer_thread);
            rt_schedule();
        }
    }
   #endif

return -RT_EOK;
}

    .........

rt_timer_stop(&thread->thread_timer);

/* enable interrupt */
    rt_hw_interrupt_enable(temp);
    
    （在此处被重入）
