Wiced DMA use...

[Anonymous]

WICED WiFi(2.4.1)-> sample code," Apps/Snip/Spi_Flash_Read " on the above code SPI Use DMA is given, What all changes do  need so that DMA could enable?

In option  wiced_spi_init(&wiced_spi_flash); in wiced_spi_flash bydefault they have used SPI_NO_DMA and SPI can read flash.

Instae I changed it to SPI_USE_DMA. What else I need to do?

Hi,

Did you look at the "const platform_spi_t platform_spi_peripherals[]" in SDK-3.x for setting up DMA usage in platform.c.

For SDK-2.4.1 similar setup is in platform.c with "const platform_spi_mapping_t spi_mapping[]" definitions.
