我用的芯片是STM32F429
STLINK进行调试
调试的时候不停的报这个警告。

我的程序首先运行的是这个函数。当运行到标红的那句时，调试箭头消失，无法继续进行调试。于是乎，我就退出了调试。当我再次点击调试时，系统提示：无法连接到设备了。
于是，我用STM32 ST-LINK Utility选择 select "Connect Under Reset" mode from Target->Settings menu 。进行连接，然后擦除芯片，才可以进行下一次调试。


GPIO_InitTypeDef GPIO_InitStructure;

        RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOA, ENABLE);
        RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOB, ENABLE);
        RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOC, ENABLE);
        RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOD, ENABLE);

        //***************************************************************************
        /* PA输出 */
        GPIO_InitStructure.GPIO_Pin =  GPIO_Pin_0|GPIO_Pin_1|GPIO_Pin_2|GPIO_Pin_3|GPIO_Pin_4;
        GPIO_InitStructure.GPIO_Mode = GPIO_Mode_OUT;       
        GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;       
        GPIO_InitStructure.GPIO_OType=GPIO_OType_PP;      
        GPIO_InitStructure.GPIO_PuPd= GPIO_PuPd_NOPULL;
        GPIO_Init(GPIOA, &GPIO_InitStructure);



我怀疑应该是我程序的问题：
我的 stm32f4xx_adc.c里面有这个


/* ADC CCR register Mask */
#define CR_CLEAR_MASK             ((uint32_t)0xFFFC30E0)  

我的stm32f4xx_dac.c里面也有这个
/* CR register Mask */
#define CR_CLEAR_MASK              ((uint32_t)0x00000FFE)


是不是这个东西引起的问题？是不是我的这两个文件有问题？
