稚晖君您好，我最近在使用stm32f103c8t6开发的时候，遇到了 cubemx生成的工程uart dma传输失败的问题，经过debug发现是cubemx生成的工程的初始化部分 dma初始化在uart初始化之后，如图，我手动将其调整到uart初始化之前，就好使了。如

但是比较郁闷的是，这个问题好像是随机出现的，我的另一个工程就是dma在uart初始化之前，如图

请问您遇到过这个问题吗，如果遇到过，是怎么避免的呢，我现在好像只能每次都手操将其位置改变一下，但如果使用cubemx重新生成代码，还要再次手动改变位置

cubemax是可以修改初始化顺序的，在project Manager -> Advanced settings 中可以设置
