我现在在使用S32K312开发，在使用DMA时遇到一些问题：
DMA在正常传输数据，但当我修改DMA源地址数据时，传输到目的地址的数据依旧是原先的值。
但是我发现在我改变DMA源地址数据后手动调用sys_m7_cache_clean()后，传输到目的地址的数据是更新值。
我想知道是不是我的工程有什么地方配置需要调整。
I am currently developing with S32K312 and am having some problems with DMA:
DMA is transmitting data normally, but when I modify the DMA source address data, the data transferred to the destination address is still the original value.
But I found that after I manually called sys_m7_cache_clean() after changing the DMA source address data, the data transferred to the destination address was the updated value.
I would like to know if there is any configuration of my project that needs to be adjusted.
