您可以尝试在Halcogen中 TMS570LC4357 > R5-MPU-PMU > Cortex-R5 > 取消选中 Enable Cache 或者将缓存配置为write through 模式，以确保RAM和缓存中的数据匹配 启用
To handle this situation, I break up the DMA initiation calls to the size of the block the DMA can send with larger blocks being at least 256 bytes so the call to "DSPI_MasterTransferEDMA" that is located within the Callback can complete before the DMA interrupt is requested again...
