STM32F103下载程序后不运行

主要问题如题目。KEIL5 V2.26搭配最新版本的pack，（因为之前用V5.18也不运行，就换了新版本）。仿真的话在RCC里面出不来，已经选中了run to main 。这是为什么呢？怀疑是少写了什么程序问题，还是？？
下面是主程序；（测量引脚与PWM引脚均不对）
int main(void)
{
RCC_Configuration();
NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2);
LED_Init();
TIM2_PWM_Init(9999,143); //50Hz
TIM_SetCompare1(TIM2,5000); //50Hz
TIM_SetCompare2(TIM2,4000); //50Hz
TIM_SetCompare3(TIM2,3000); //50Hz
TIM_SetCompare4(TIM2,2000); //50Hz
