Subject: Troubles with wl12xx
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
Sender: linux-wireless-owner@vger.kernel.org
List-ID: <linux-wireless.vger.kernel.org>

I'm having some issues getting my [newly designed] board to run
with wl12xx (wl1271 on SDIO)  My kernel is 2.6.37 and I'm using
a compat-wireless snapshot from 2012-02-28

Here's what I see when I boot - looks OK:
   Compat-wireless backport release: compat-wireless-2012-02-28
   Backport based on linux-next.git next-20120228
   cfg80211: Calling CRDA to update world regulatory domain
   wl12xx: loaded

If I bring up the wlan0 interface manually, I can talk to the
device, scan for access points, etc.  All looks good.

The problem comes when I try to negotiate for an address with
WPA security.
   # ifup wlan0
   wl12xx: firmware booted (Rev 6.3.5.0.98)
   ADDRCONF(NETDEV_UP): wlan0: link is not ready
   udhcpc (v1.19.3) started
   Sending discover...
   wl12xx: down
   Sending discover...
   Sending discover...
   No lease, failing

A few seconds later, everything falls apart.  Sorry for the verbosity, but
the messages changed at the end and I wanted to make sure you saw it all.

Any ideas what causes this problem & how I can solve it?

Note: I'm using the very latest TI firmware
