Hi there,
I decided to try to create a quick patch to implement support for the bbtoys-wifi adapter board (wl1271/ls240) in the 2.6.37 kernel from Devkit 2.1 Gingerbread. I have attached the patch to add the wifi structures, dot config for the kernel and boot log.

wlan0 Interface doesn't support scanning : Network is down
I was successful in getting the wlan0 interface to show up. But I can't seem to get the interface to come up so that scanning and other iwconfig steps can occur. I checked for the following:
a) pinmux in u-boot
Recognized BeagleBoardToys WiFi board
(above sets up the correct pinmux for the use of MMC2 pins)

wlan0 Interface doesn't support scanning : Network is down
As can be seen, the first indication of failure is at step f. I'm not sure what the root cause is yet. I've tested that this same setup works with 2.6.39. Has anyone been successful in making Devkit 2.1 Gingerbread work on Beagleboard-XM with the BBtoys-Wifi adapter board?
Thanks,
jaya
