    Usage of WWD_PIN_SPI_IRQ in BCM943362WCD4

    hari.cr

      I'm trying to interface SN8000x module with my custom board using SPI, So I took BCM943362WCD4 platform file as reference

       

      In platform.c of BCM943362WCD4 I could see that

       

      /* Wi-Fi gSPI bus pins. Used by WICED/platform/STM32F2xx/WWD/wwd_SPI.c */

      const platform_gpio_t wifi_spi_pins[] =

      {

         [WWD_PIN_SPI_IRQ ] = { GPIOC,  9 },

          [WWD_PIN_SPI_CS  ] = { GPIOC, 11 },

          [WWD_PIN_SPI_CLK ] = { GPIOB, 13 },

          [WWD_PIN_SPI_MOSI] = { GPIOB, 15 },

          [WWD_PIN_SPI_MISO] = { GPIOB, 14 },

      };

      In I understood that WWD_PIN_SPI_IRQ is the line DAT1 from the SN8000x module board, But as per my schematics

      DAT1 is not connected to anywhere.. So Can I really interface the SN8000x module using SPI on my custom board ?
