stm32f103ZET6 库函数中使用 ADC + DMA 循环模式时烧录失败

使用环境

操作系统版本：Windows10
操作系统平台(x86/x64)：x64
VsCode 版本：1.73.0
EIDE 插件版本：3.10.0
C/C++ 插件版本：v1.13.3
何种编译器(keil_c51/sdcc/armcc5/armgcc/...)：armcc5
编译器版本(非编译问题可忽略)：

描述问题

stm32f103zet6 库函数中使用 ADC + DMA 循环读取模式导致烧录失败
使用 CMSIS-DAP 仿真器
烧录配置为 OpenOcd
芯片配置 stm32f1x.cfg
接口配置 cmsis-dap.cfg

当使用 ADC + DMA 循环模式时, 第一次烧录成功且程序正确运行, 但再次烧录其他程序均出错
需要芯片复位后才能再次烧录
测试使用 USART + DMA 从内存到外设模式发送数据没有问题

具体代码

int main()
{
    uint16_t ADC_ConvertedValue = 0;

	ADC_InitTypeDef ADC_InitStructure;

	DMA_InitStructure.DMA_BufferSize = 1; //传输内容的大小
	DMA_InitStructure.DMA_PeripheralInc = DMA_PeripheralInc_Disable; //外设地址固定
	DMA_InitStructure.DMA_MemoryInc = DMA_MemoryInc_Disable; //内存地址固定
	DMA_InitStructure.DMA_PeripheralDataSize = 
	DMA_PeripheralDataSize_HalfWord ; //外设数据单位
	DMA_InitStructure.DMA_MemoryDataSize = 
	DMA_MemoryDataSize_HalfWord ;    //内存数据单位
	DMA_InitStructure.DMA_Mode = DMA_Mode_Circular  ; //DMA模式：循环传输
	DMA_InitStructure.DMA_Priority = DMA_Priority_High ; //优先级：高
	DMA_InitStructure.DMA_M2M = DMA_M2M_Disable;   //禁止内存到内存的传输
	
	DMA_Init(DMA1_Channel1, &DMA_InitStructure);  //配置DMA1的4通道
	DMA_Cmd(DMA1_Channel1,ENABLE);
 
	ADC_InitStructure.ADC_Mode = ADC_Mode_Independent; //独立ADC模式
	ADC_InitStructure.ADC_ScanConvMode = DISABLE;  //禁止扫描方式
	ADC_InitStructure.ADC_ContinuousConvMode = ENABLE;//开启连续转换模式 
	ADC_InitStructure.ADC_ExternalTrigConv = ADC_ExternalTrigConv_None; //不使用外部触发转换
	ADC_InitStructure.ADC_DataAlign = ADC_DataAlign_Right; //采集数据右对齐
	ADC_InitStructure.ADC_NbrOfChannel = 1; //要转换的通道数目
	ADC_Init(ADC1, &ADC_InitStructure);
	
	RCC_ADCCLKConfig(RCC_PCLK2_Div8);//配置ADC时钟，为PCLK2的8分频，即9Hz
	ADC_RegularChannelConfig(ADC1, ADC_Channel_11, 1, ADC_SampleTime_55Cycles5);//配置ADC1通道11为55.5个采样周期 
	
	ADC_DMACmd(ADC1,ENABLE);
	ADC_Cmd(ADC1,ENABLE);
 
	ADC_ResetCalibration(ADC1);//复位校准寄存器
	while(ADC_GetResetCalibrationStatus(ADC1));//等待校准寄存器复位完成
 
	ADC_StartCalibration(ADC1);//ADC校准
	while(ADC_GetCalibrationStatus(ADC1));//等待校准完成
 
	ADC_SoftwareStartConvCmd(ADC1, ENABLE);//由于没有采用外部触发，所以使用软件触发ADC转换
}

不清楚是什么原因，本来 openocd 问题也挺多的

你可以试一下最新版本的 0.12.0-rc2，后面将使用该版本

似乎还是不行, 不过错误信息倒是变了
测试用单独使用单通道 ADC 也没有问题
似乎找到问题的根源了, 应该就是 DMA_DeInit(DMA1_Channel1); 导致的问题, 注释掉之后就正常了
这句是按教程写的, 但越想越奇怪, 明明是第一次使用 DMA 没必要复位, 直接注释掉结果就正常了
虽然问题算是解决了, 不过还是挺好奇背后的原因是什么, 因为这个函数就只是复位 DMA1_Channel1

好吧, 还是有问题, 只是刚才以为解决了太激动就发出来了, 非常抱歉
冷静下来认真定位了一下出错的地方
当 DMA_Cmd, DMA_Init, ADC_Cmd, ADC_Init, ADC_DMACmd, ADC_SoftwareStartConvCmd 当中任意一个被注释时错误均消失
这函数功能分别是开启 DMA 功能, 初始化 DMA, 开启 ADC 功能, 初始化 ADC, 开启 ADC, DMA 功能, 开启 ADC 软件触发, 也就是说只要 ADC + DMA 没有被正常开启就不会出错
注释 ADC 扫描通道配置函数 ADC_RegularChannelConfig 与被读取引脚的 GPIO 的初始化, 问题仍然存在

今天早上再试了一下, 只要在再次烧录前关闭 DMA 或 ADC 或关闭ADC连续转换模式, 烧录就不会出错
