Here is an example of interfacing the BCM43362 based SN8000 WiFi module (from Murata) with STM32F4-Discovery board (with STM32F407 MCU).
The schematic below illustrates the connections required to connect the SN8000 to the STM32F4-Discovery board. Since the SN8000 comes as a module to connect to a PCB, a carrier board is needed to connect the module to the STM32F4-Discovery board.
If you have the SN8000 module mounted on a SDIO carrier board, which comes with the SN800 evaluation board, the following connection schema can be used to connect the module to the STM32F4-Discovery board.
For terminal interface between the STM32F4-Discovery board and host PC the following serial (RS232) connection is needed.
To connect a JTAG debugger (Olimex_ARM-USB-TINY-H) to the STM32F4-Discovery board follow the below connection.

After setting up the hardware connections WICED SDK-3.x should be updated to run WICED applications on STM32F4-Discovery board with SN8000 WiFi module. Unzip the attached file with the following expected updates.
The STM32F407 directory goes to .../WICED/platform/MCU/STM32F4xx/GCC directory of the WICED SDK.
The STDiscovery407_BCM43362 platform files goes to .../platforms directory of the WICED SDK.
To build and run application using WICED SDK following Make Target could be used;
<Application>-STDiscovery407_BCM43362 JTAG=Olimex_ARM-USB-TINY-H download run
To build and run a sample scan app use the following Make Target:
snip.scan-STDiscovery407_BCM43362-debug JTAG=Olimex_ARM-USB-TINY-H download run
