ucosii 移植 STM32F407VET6 外接晶振24M 跑马灯运行不成功

我直接使用原子的探索者F4资料的例程，讲ucosii复制到我建立的项目里，我的板子硬件是STM32F407VET6,外接晶振24M，已经将stm32f4xx.h中的“HSE_VALUE”改为24000000，system_stm32f4xx.c 中“#define PLL_M” 改为24，代码如下

[mw_shl_code=c,true]#if !defined (HSE_VALUE) #define HSE_VALUE ((uint32_t)24000000) /*!< Value of the External oscillator in Hz */ #endif /* HSE_VALUE */[/mw_shl_code]

[mw_shl_code=c,true]#if defined (STM32F40_41xxx) || defined (STM32F427_437xx) || defined (STM32F429_439xx) || defined (STM32F401xx) /* PLL_VCO = (HSE_VALUE or HSI_VALUE / PLL_M) * PLL_N */ #define PLL_M 24 #else /* STM32F411xE */ #if defined (USE_HSE_BYPASS) #define PLL_M 24 #else /* STM32F411xE */ #define PLL_M 16 #endif /* USE_HSE_BYPASS */ #endif /* STM32F40_41xxx || STM32F427_437xx || STM32F429_439xx || STM32F401xx */ [/mw_shl_code] [mw_shl_code=c,true]主函数为

[mw_shl_code=c,true]void start_task(void *pdata) { OS_CPU_SR cpu_sr=0; pdata = pdata; OS_ENTER_CRITICAL(); //???????????¨??·¨±??????ò???© OSTaskCreate(led0_task,(void *)0,(OS_STK*)&LED0_TASK_STK[LED0_STK_SIZE-1],LED0_TASK_PRIO); OSTaskCreate(led1_task,(void *)0,(OS_STK*)&LED1_TASK_STK[LED1_STK_SIZE-1],LED1_TASK_PRIO); OSTaskSuspend(START_TASK_PRIO); //???????????? OS_EXIT_CRITICAL(); //???????????¨????±??????ò???© } //LED0???? void led0_task(void *pdata) { while(1) { LED0=0; delay_ms(80); LED0=1; delay_ms(920); }; } //LED1???? void led1_task(void *pdata) { while(1) { LED1=0; delay_ms(300); LED1=1; delay_ms(300); }; }[/mw_shl_code]

运行情况是LED0直接常亮，没有按照程序规定的开始闪烁，LED1不亮，求助是移植没有成功？还是线程没有运行？[/mw_shl_code]
