rismi Question

Hi,

We are trying to implement SPI DMA operation in BF609 board.where SPI will communicate with SPI_FLASH and reads N data through DMA. We are not able to configure and read data in SPI DMA mode. But we have achieved this with NON DMA mode.The reference manual also doesn't gives a clear explanation on this.

Could you please provide an simple example code to operate SPI read operation in DMA mode?

We also tried the SPI DMA Driver given by analog devices,where we getting ADI_SPI_CONFIGURATION_ERROR while executing adi_spi_SubmitBuffer(hDevice, &Transceiver1) present in that driver.

Thank You..

Hi Rishi,

I could find one example in my code-box. It was written in some particular context for BF707; so not sure how much it would help you. But please go through it and let me know if you need more details.
