    SPI MISO on CYW43907

    jahoc_3635086

      I am working with the spi_new example in the blog post :

      SPI in CYW43907

       

      The SPI MISO line does not respond for either SPI1 or SPI2 when using the spi_gsio_driver. When using the spi_bb_driver I can receive data IF I use an alternate GPIO for the MISO pin.

       

      The MISO for SPI1 also cannot be used as a GPIO, when configured as an IO (wiced_gpio_init), yet when SPI is not initialized this pin is toggling.

       

      The software BB driver works great but I need at least 5Mhz clock speed for my application.

       

      Does anyone have any idea why the MISO lines are dead with the spi_gsio_driver?
