ucos Data Abort 怪问题

最近碰到个怪问题..在UCOS中.我的一个电机控制任务.如果用定时器来产生输出脉冲.运行10多分钟就会产生 data abort interrupt.. 如果用OSTimeDly(1);延时产生,,就不会,,定时器时发一个消息.. 电机控制任务是等待消息,,..怪,, 下面是部分程序:
void    MotorCtrolTask(void *pdata)
{    //INT8U    Error;
    INT8U    i=0;
    pdata =  pdata;
    MotorInit();
    while(1)
    {
            //OSSemPend(MotorRunSem,0,&Error);               /*µÈ´ýmotor out enable ÐÅºÅÁ¿ */
            OSTimeDly(1);
            if(MotorStatus == STOP)
            {
                MotorStatus = INCREASE;
            }
            else
            {    MOTORCLK_1;
                for(i=0;i<30;i++);
                switch(MotorStatus)
                {    case INCREASE:    MotorIncreaseRate++;
                                    if(MotorIncreaseRate>MOTORRATE)
                                    {    MotorIncreaseRate = 0;
                                        MotorStartStep++;
                                        if(MotorStartStep>=STARTSTEP)
                                        {    MotorStatus = RUN;
                                            MotorStartStep = STARTSTEP;
                                        }
                                        MotorStartStopControl(MotorStartStep);
                                    }
                                    break;
                    case DECREASE:    MotorIncreaseRate++;
                                    if(MotorIncreaseRate>MOTORRATE)
                                    {    MotorIncreaseRate = 0;
                                        if(MotorStartStep>0)
                                        {    MotorStartStep--;
                                            MotorStartStopControl(MotorStartStep);
                                        }
                                        else
                                        {    MotorStatus = STOP;
                                            MOTORRESET_0;
                                            MOTORRESET_1;
                                            MOTORCLK_0;
                                        }
                                    }
                                    break;
                    default:        break;
                }
                OSTimeDly(1);
                MOTORCLK_0;
            }
    }

IRQ_STACK_LEGTH EQU 9*15

修改了这个就可以了,,我想应该是椎栈设的太小了, 原来的是 9*8的..按ZLG给我们的模板来的,
