AM6442: BCDMA数据搬运回写失败

Part Number: AM6442

我这边是想初始化5个BCDMA出来,每次需要用DMA搬运数据的时候会自动调用空闲的一个,现在问题在于在StructDMA.c中,我调用BCDMA_MemoryCopy()搬运数据之后在BCDMA_CheckCopyStatus()里面调用Udma_ringDequeueRaw()检测数据是否搬运完成,完成之后进行CacheP_inv()数据的回写,但是这里如果回写了这个程序就跑乱了,如果这里不调用CacheP_inv()在目标地址&data又看不到更新的数据,怎么弄struct_am64x-evm_r5fss0-0_nortos_ti-arm-clang.rar
