MSPM0G1507: dma+ADC 转换,debug第一次运行正常，复位或者非debug状态dma输出全为0

mao wenqi

Part Number: MSPM0G1507

使用芯片：MSPM0G1507
目的：DAC输出指定信号，ADC根据定时器采样数据通过串口发出来
基于定时器触发dma进行adc采样，第一次debug运行都正常，脱离调试也正常，但是在调试中rest芯片，DMA输出数组值全为0，硬件脱离调试重新启动，DMA输出值也全为0，系统主时钟80M
与此同时DAC+DMA输出永远正常，部分时候会出现systick中断不触发的情况
具体配置如下：

syscfg:

不正常（调试界面点复位或者硬件上reset引脚给一次低电平脉冲）：

ccs和keil同样现象
