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

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

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:

# ifconfig wlan0 up

What could the reason be?
