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:

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:

I tried that earlier, but got the same results. 

# ifconfig wlan0 hw ether 11:22:33:44:55:66
SIOCSIFHWADDR: Cannot assign requested address

Even trying to assign an IP address doesn't work. 

# ifconfig wlan0 inet 192.168.1.105 netmask 255.255.255.0
SIOCSIFFLAGS: Cannot assign requested address


Here's how my modified board-omap3beagle.c looks like, for the mainline wl1271 drivers. (The modifications for the board file and the board-wifi for the TI proprietary drivers are different, and that is a separate issue that I'm working on in parallel for android-2.6.32 kernel).

Ethernet addresses with the LSB of the first octet turned on are
considered multicast addresses. Please try:

ifconfig wlan0 hw ether 00:22:33:44:55:66

That worked, now the only thing is to put the firmware file in the appropriate place, I guess:

# ifconfig wlan0 hw ether 00:22:33:44:55:66

# ifconfig wlan0 up

[  153.843597] wl1271: ERROR could not get firmware: -2

Where should the firmware file be located? /etc/firmware ?

The firmware file should be called wl1271-fw.bin and the nvs file
should be called wl1271-nvs.bin. Both should reside in /etc/firmware
(if you're running a standard linux).

I got the files from this git repo 

git clone git://git.kernel.org/pub/scm/linux/kernel/git/dwmw2/linux-firmware.git

and copied them over to /etc/firmware

/etc/firmware# ls -l
total 276
-r--r--r-- 1 root root 271712 Dec 17  2010 wl1271-fw.bin
-rw-rw-r-- 1 root root    912 Dec 17  2010 wl1271-nvs.bin

But I still get a error saying the the nvs file could not be found:

[   63.852264] wl1271: ERROR could not get nvs file: -2

:-) Ok, that's understandable!! My final aim is to get this working with android-2.2.1. Have you done a port of the android kernel to 2.6.37 already ?

Where should the firmware file be located? What name should I give the firmware file : firmware.bin ? 

I get the following error after adding the following patch:
