Hi James,

DMA is enabled by default when SDIO is initialized but for SPI, DMA can't be enabled with CYW54907.

Thanks.

Hi James,

By default, block mode is enabled with DMA and we don't recommend making changes in the default implementation.

Can you please provide us some more insights about your requirement.

Thanks.

hi

We want spi and dma working parallelly

we will get data from ACIS continually through SPI bus.

In the meantime, the data need to write back to sd card

in CYW54907

By the way, can we set spi SCK duty cycle

Hi James,

I regret to inform you that we can't set SPI SCK duty cycle as it is fixed by hardware.
Also, we don't have any provision to change the duty cycle for SPI SCK. 

Thanks.
