Hello.
My Platform is BCM9WCDUSI09 and SDK 3.1.2
I have downloaded "BCM9WCDUSI09.zip" file.
below are 233 line and 238 line of platform.c file
const platform_gpio_t wifi_control_pins[] =
{
[WWD_PIN_POWER ] = { GPIOC, 7 },
[WWD_PIN_RESET ] = { GPIOC, 1 },
//#if defined ( WICED_USE_WIFI_32K_CLOCK_MCO )
[WWD_PIN_32K_CLK ] = { GPIOB, 1 }, -----> 233 line
//#else
// [WWD_PIN_32K_CLK ] = { GPIOA, 11 },
//#endif
[WWD_PIN_BOOTSTRAP_0] = { GPIOB, 0 },
[WWD_PIN_BOOTSTRAP_1] = { GPIOB, 1 }, -------> 238 line
};
{GPIOB, 1} is duplicated.
Is it right?
Thanks.

The WiFi chip selects the mode of communication SPI / SDIO by cheking the status of Bootstrap pins at the start up , and I think this wont be needing later. The 32 K MCO is used supply the clock while the WiFi chip is in power saver mode to wake up properly which can be enabled after chosing the mode of communication..
