请教大神，STM32F302CC芯片AD校准死循环的问题

请教大神，本人现在在做一个AD信号转换，然后DMA存储到FLASH的开发。发现AD在初始化过程中，进入校准步骤，WHILE条件判断会进入死循环，请大神帮小弟看看问题出在哪里，谢谢！

系统时钟配置：
//Configures the different system clocks.
void SYS_RCC_Config(void)
{   
   
    /* RCC system reset(for debug purpose) */
     RCC_DeInit();
   
    //使用内部晶振
    RCC_HSICmd(ENABLE);
    /* Disable HSE */
    RCC_HSEConfig(RCC_HSE_OFF);
   
    /* Enable Prefetch Buffer */
//    FLASH_PrefetchBufferCmd(FLASH_PrefetchBuffer_Enable);
    FLASH_PrefetchBufferCmd(ENABLE);
    /* Flash 2 wait state */
    FLASH_SetLatency(FLASH_Latency_2);
    /* HCLK = SYSCLK */
    RCC_HCLKConfig(RCC_SYSCLK_Div1); //AHB
    /* PCLK1 = HCLK/2 */
    RCC_PCLK1Config(RCC_HCLK_Div2);//AHB1
    /* PCLK2 = HCLK */
    RCC_PCLK2Config(RCC_HCLK_Div1); //AHB2
    /* ADCCLK = PCLK2/4 */
    RCC_ADCCLKConfig(RCC_ADC12PLLCLK_Div4); //AD是12MHz主频
    /* PLLCLK = (8/2)MHz * 12 = 48 MHz */
    RCC_PLLConfig(RCC_PLLSource_HSI_Div2, RCC_PLLMul_12); //内部8M
    /* Enable PLL */
    RCC_PLLCmd(ENABLE);
    /* Wait till PLL is ready */
    while(RCC_GetFlagStatus(RCC_FLAG_PLLRDY) == RESET)
    { }
    /* Select PLL as system clock source */
    RCC_SYSCLKConfig(RCC_SYSCLKSource_PLLCLK);
    /* Wait till PLL is used as system clock source */
    while(RCC_GetSYSCLKSource() ！= 0x08)
    { }
   
}//End of function;
AD初始化代码
void CAP_ADCDMAInit(void)
{
    GPIO_InitTypeDef GPIO_InitStructure;
    NVIC_InitTypeDef NVIC_InitStructure;
    ADC_InitTypeDef ADC_InitStructure;
    ADC_CommonInitTypeDef ADC_CommonInitStructure;

    RCC_AHBPeriphClockCmd(RCC_AHBPeriph_DMA1 | RCC_AHBPeriph_ADC12, ENABLE);
    NVIC_InitStructure.NVIC_IRQChannel = DMA1_Channel1_IRQn;
    NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
    NVIC_InitStructure.NVIC_IRQChannelSubPriority = 2;
    NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
    NVIC_Init(&NVIC_InitStructure);
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_1;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AN;
    GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_NOPULL;
    GPIO_Init(GPIOA, &GPIO_InitStructure);
   
    ADC_StructInit(&ADC_InitStructure);
    // Calibration procedure
    ADC_VoltageRegulatorCmd(ADC1, ENABLE);
    // Insert delay equal to 10 us
    Tim_usDelay(10);
    ADC_SelectCalibrationMode(ADC1, ADC_CalibrationMode_Single);
    ADC_StartCalibration(ADC1);
    while (ADC_GetCalibrationStatus(ADC1) ！= RESET);（进入死循环的地方）

    calibration_value = ADC_GetCalibrationValue(ADC1);
    ADC_CommonInitStructure.ADC_Mode = ADC_Mode_Independent;
    ADC_CommonInitStructure.ADC_Clock = ADC_Clock_SynClkModeDiv4;//AD是12MHZ主频
    ADC_CommonInitStructure.ADC_DMAAccessMode = ADC_DMAAccessMode_Disabled;
    ADC_CommonInitStructure.ADC_DMAMode = ADC_DMAMode_OneShot;
    ADC_CommonInitStructure.ADC_TwoSamplingDelay = 0;
    ADC_CommonInit(ADC1, &ADC_CommonInitStructure);
    ADC_InitStructure.ADC_ContinuousConvMode = ADC_ContinuousConvMode_Enable;
    ADC_InitStructure.ADC_Resolution = ADC_Resolution_12b;
    ADC_InitStructure.ADC_ExternalTrigConvEvent = ADC_ExternalTrigConvEvent_0;
    ADC_InitStructure.ADC_ExternalTrigEventEdge = ADC_ExternalTrigEventEdge_None;
    ADC_InitStructure.ADC_DataAlign = ADC_DataAlign_Right;
    ADC_InitStructure.ADC_OverrunMode = ADC_OverrunMode_Disable;
    ADC_InitStructure.ADC_AutoInjMode = ADC_AutoInjec_Disable;
    ADC_InitStructure.ADC_NbrOfRegChannel = 1;
    ADC_Init(ADC1, &ADC_InitStructure);
}
AD启动代码：
void CAP_ADCDMAStart(u16* lpAddr, u32 nSignalCnt, INT_HANDLER lpfncHandler)
{
    DMA_InitTypeDef DMA_InitStructure;
    g_DMA1IRQHandler = lpfncHandler;
    // DMA channel1 configuration
    DMA_DeInit(DMA1_Channel1);
    DMA_InitStructure.DMA_PeripheralBaseAddr = ADC_DR_Address;
    DMA_InitStructure.DMA_MemoryBaseAddr = (u32)lpAddr;
    DMA_InitStructure.DMA_DIR = DMA_DIR_PeripheralSRC;
    DMA_InitStructure.DMA_BufferSize = (u32)nSignalCnt;
    DMA_InitStructure.DMA_PeripheralInc = DMA_PeripheralInc_Disable;
    DMA_InitStructure.DMA_MemoryInc = DMA_MemoryInc_Enable;
    DMA_InitStructure.DMA_Mode = DMA_Mode_Normal;
    DMA_InitStructure.DMA_Priority = DMA_Priority_High;
    DMA_InitStructure.DMA_M2M = DMA_M2M_Disable;
    DMA_InitStructure.DMA_PeripheralDataSize = DMA_PeripheralDataSize_HalfWord;
    DMA_InitStructure.DMA_MemoryDataSize = DMA_MemoryDataSize_HalfWord;
    DMA_Init(DMA1_Channel1, &DMA_InitStructure);
    DMA_ITConfig(DMA1_Channel1, DMA_IT_TC, ENABLE);
    DMA_Cmd(DMA1_Channel1, ENABLE);
      
    ADC_RegularChannelConfig(ADC1, ADC_Channel_2, 1, ADC_SampleTime_1Cycles5);
        
    ADC_Cmd(ADC1, ENABLE);
    /* wait for ADRDY */
    while (！ADC_GetFlagStatus(ADC1, ADC_FLAG_RDY));
      
    /* ADC1 DMA Enable */
    ADC_DMACmd(ADC1, ENABLE);
    ADC_DMAConfig(ADC1, ADC_DMAMode_OneShot);
    ADC_StartConversion(ADC1);
}//End of function;

你的意思是程序一直死在ADC校准那儿么?程序直接下载的还是debug模式
