    Hi,

    In order to work with the WL1271 module you will have to set the Muxing correctly to connect the WL1271 to the SDIO bus (need to verify which MMC is connected in that board), in addition WL1271 needs GPIO that will work as WLAN_en signal and IRQ line.

    Please refer to WiKi page on that subject http://processors.wiki.ti.com/index.php/OMAP_Wireless_Connectivity_Hardware_Porting_for_new_Platform

    Regards,

    Eyal
