求助，stm32f407 IAP工作异常问题，请问是否为DMA配置错误？

这问题已经折腾数日，我是按照正点原子的stm32f4的IAP程序更改了一版自己的程序，功能就是接收串口5的代码然后写入FLASH,完成之后运行APP，测试APP已经通过，并且查看FLASH代码应该是正常写入了的，但用上自己的APP始终工作异常，具体表现如下：
1. APP直接烧写工作正常。
2. APP转成BIN文件上传后工作异常，在线看BOOTLOADER的error report如附件所示报错
3.用指示灯定位发现一旦加上DMA配置则工作异常（如果屏蔽掉DMA再上传则其它功能正常），我的DMA配置如下，用于和一片DSP的SPI通信
void SPI2_CHX_DMA_Config(void)
{

      DMA_InitTypeDef  DMA_InitStructure;

      RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_DMA1, ENABLE);//DMA1 奀笘妏夔

      DMA_DeInit(DMA1_Stream3);                                                                                              //饜离 DMA

      DMA_InitStructure.DMA_BufferSize = 251;//杅擂換怀講
      DMA_InitStructure.DMA_Channel = DMA_Channel_0;//籵耋 0
      DMA_InitStructure.DMA_Memory0BaseAddr = (uint32_t)&DSPtoARM_buffer[0];
      DMA_InitStructure.DMA_PeripheralBaseAddr = (uint32_t)&(SPI2->DR);//俋扢華硊
      DMA_InitStructure.DMA_DIR = DMA_DIR_PeripheralToMemory;//俋扢善湔揣?耀宒
      DMA_InitStructure.DMA_MemoryDataSize = DMA_MemoryDataSize_Byte;
      DMA_InitStructure.DMA_PeripheralDataSize = DMA_PeripheralDataSize_Byte;

      DMA_InitStructure.DMA_MemoryInc = DMA_MemoryInc_Enable;
      DMA_InitStructure.DMA_PeripheralInc = DMA_PeripheralInc_Disable; //俋扢準崝講
      DMA_InitStructure.DMA_Mode = DMA_Mode_Normal;
      DMA_InitStructure.DMA_PeripheralBurst = DMA_PeripheralBurst_Single;
      DMA_InitStructure.DMA_MemoryBurst = DMA_MemoryBurst_Single;
      DMA_InitStructure.DMA_FIFOMode = DMA_FIFOMode_Disable;
      DMA_InitStructure.DMA_FIFOThreshold = DMA_FIFOThreshold_HalfFull;
      DMA_InitStructure.DMA_Priority = DMA_Priority_High;//DMA_Priority_VeryHigh;

      DMA_Init(DMA1_Stream3, &DMA_InitStructure);
      DMA_ITConfig(DMA1_Stream3, DMA_IT_TC, ENABLE);
      DMA_Cmd(DMA1_Stream3, ENABLE);

      DMA_DeInit(DMA1_Stream4);

      DMA_InitStructure.DMA_BufferSize = 251;
      DMA_InitStructure.DMA_Channel = DMA_Channel_0;
      DMA_InitStructure.DMA_Memory0BaseAddr = (uint32_t)&ARMtoDSP_buffer[0];
      DMA_InitStructure.DMA_PeripheralBaseAddr = (uint32_t)&(SPI2->DR);//SPI1_DR_Addr;
      DMA_InitStructure.DMA_DIR = DMA_DIR_MemoryToPeripheral;
      DMA_InitStructure.DMA_MemoryDataSize = DMA_MemoryDataSize_Byte;
      DMA_InitStructure.DMA_PeripheralDataSize = DMA_PeripheralDataSize_Byte;
      DMA1_Stream4->NDTR = 251;
      DMA_InitStructure.DMA_MemoryInc = DMA_MemoryInc_Enable;
      DMA_InitStructure.DMA_PeripheralInc = DMA_PeripheralDataSize_Byte;
      DMA_InitStructure.DMA_Mode = DMA_Mode_Normal;
      DMA_InitStructure.DMA_PeripheralBurst = DMA_PeripheralBurst_Single;
      DMA_InitStructure.DMA_MemoryBurst = DMA_MemoryBurst_Single;
      DMA_InitStructure.DMA_FIFOMode = DMA_FIFOMode_Disable;
      DMA_InitStructure.DMA_FIFOThreshold = DMA_FIFOThreshold_HalfFull;
      DMA_InitStructure.DMA_Priority = DMA_Priority_High;//DMA_Priority_High;

      DMA_Init(DMA1_Stream4, &DMA_InitStructure);
      DMA_ITConfig(DMA1_Stream4, DMA_IT_TC, ENABLE);
      DMA_Cmd(DMA1_Stream4, ENABLE);
      delayms(1);
}

强调一下，我的APP是能通过仿真器正常烧写的，而BOOTLOADER也是通过了APP测试的，但是加上了DMA配置的APP就通不过，头大！！！
请问各位高手，是不是我的DMA配置有误？像这样无法在线查看的情况，我应该使用什么样的调试方法？
多谢名位。
