Subject: Problems with wl1271
Date: Wed, 29 Feb 2012 13:53:15 -0700 [thread overview]
Message-ID: <4F4E903B.2030501@mlbassoc.com> (raw)
I'm trying to bring up a new hardware platform which includes
the TiWi-r02 (wl1271). Since the kernel for my target device
(AM3874) is stuck in the dark ages, Luciano suggested that I
try compat-wireless + iw. I've managed to build these now
(after encountering many problems that I'll help iron out later)
and now have the system ready to start using the device. Note:
I'm using compat-wireless-2012-02-28 and iw-3.2
The kernel modules load and initialize now, with these messages:

wl12xx: loaded
When I try to bring up the device, I get this:

# ifconfig wlan0 up
wl12xx: firmware booted (Rev 6.3.5.0.98)

If I try to scan for an access point, I get nothing:
# iw wlan0 scan

I also see no additional messages in dmesg.
Further checking of the device:

WoWLAN support:
* wake up on anything (device continues operating normally)
Device supports AP-side u-APSD.
I don't know enough about this device to understand why it's not working.
Perhaps the line
Available Antennas: TX 0 RX 0
is a clue?
Any ideas what's not working & how I need to do to move forward?
Thanks in advance for all the help
