Hi Elvis,
This because you havent set the mac address for wlan0
wlan0 Link encap:Ethernet HWaddr 00:00:00:00:00:00
You can do by using the following command:
ifconfig wlan0 hw ether 11:22:33:44:55:66
OR
add the following patch

Subject: Problem bringing up wlan0 interface up with mainline wl1271 drivers

The linux-omap community can help you with mainline drivers, but no so
much with proprietary ones. Why don't you use the upstream wl12xx
driver ?
I've built linux kernel 2.6.37-rc6, and patched board-omap3beagle.c to
interface with MMC2 SDIO controller,
but I'm unable to bring the wlan0 interface up.
Here are the messages during kernel boot:
