I am using CYW43907 for development. In this application, large amount of data is moving from SPI to memory and memory to memory. Currently, it take a lot of CPU time for such movement. Are there any SPI DMA and memory to memory DMA example for CYW43907 ?
You may find Re: Is there any example where it uses DMA SPI? this thread useful. The DMA for 43907 is not really exposed so applications on top can't really use that. The DMA engine is basically used for communication between APPS core and WLAN core but is not really use able by the CSC blocks
