重新启动后adc采样概率性所有值为0，请问怎么解决

[ethan]

因为同时采样了芯片内部的温度adc，理论上不能所有adc的值都是0，请帮忙看看
代码如下：
typedef struct

};

};

重启后有部分概率发现包括mcu内置温度的adc以及其他所有adc通道数值为0，请问怎么调试和定位问题

[Diga]

.destAddr = (uint32_t)&ADC0_Control.ADC_ConversionBuff,//g_adc_result[0U],
这个是不是有点问题？ADC0_Control.ADC_ConversionBuff 已经是指针了，又对指针进行取址。
另外如果要调试的话，可以把ADC->FIFO 的高16bit也拿出来，里面显示了当前ADC转换结果的通道号，即DMA 一次搬运4个bytes

[ethan]

Diga 改过了这个以后，也是一样的问题。
详细描述一下，漏了一个提示，就是application单独这样运行没问题，从bootloader跳转到application以后，applicaiton里面的adc概率性不工作，bootloader程序没有对adc和dma进行任何操作

你可以把ADC->FIFO 的高16bit拿出来，check通道号有没有问题。
ADC只要使能了，触发一下就会工作，你可以check一下ADC的功能时钟是不是受到影响
