移植到STM32的是uC/OS官网的uC/OS-II V2.92，程序设置Led闪烁1s一次，但是实际调试的时候，Led闪烁的时间是2s一次。给出源代码，希望大家看看是什么问题？
cpu时钟获取：
CPU_INT32U BSP_CPU_ClkFreq (void)
{
RCC_ClocksTypeDef rcc_clocks;
RCC_GetClocksFreq(&rcc_clocks);
return ((CPU_INT32U)rcc_clocks.HCLK_Frequency);
}
设置SysTick时钟滴答重载值：
hclk_freq = BSP_CPU_ClkFreq(); /* Determine SysTick reference freq. */
cnts = hclk_freq / (CPU_INT32U)OS_TICKS_PER_SEC; /* Determine nbr SysTick increments in OS_TICKS_PER_SEC. */
OS_CPU_SysTickInit(cnts);
初始化SsyTick函数及开中断：
void OS_CPU_SysTickInit (INT32U cnts)
{
OS_CPU_CM3_NVIC_ST_RELOAD = cnts - 1u;
/* Set prio of SysTick handler to min prio. */
OS_CPU_CM3_NVIC_PRIO_ST = OS_CPU_CM3_NVIC_PRIO_MIN;
/* Enable timer. */
OS_CPU_CM3_NVIC_ST_CTRL |= OS_CPU_CM3_NVIC_ST_CTRL_CLK_SRC | OS_CPU_CM3_NVIC_ST_CTRL_ENABLE;
/* Enable timer interrupt. */
OS_CPU_CM3_NVIC_ST_CTRL |= OS_CPU_CM3_NVIC_ST_CTRL_INTEN;
}
我移植uC/OS-II V2.86的版本，没有什么问题，只是V2.92是针对F107评估板的，但是它和F103在时钟模块应该没啥区别啊，初始化RCC后均为72MHz，求学习交流！
