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: cfg80211: Updating information on frequency 5200 MHz for a 20 MHz width channel with regulatory rule: cfg80211: 5170000 KHz - 5250000 KHz @ 40000 KHz), (600 mBi, 2000 mBm) cfg80211: Updating information on frequency 5210 MHz for a 20 MHz width channel with regulatory rule: cfg80211: 5170000 KHz - 5250000 KHz @ 40000 KHz), (600 mBi, 2000 mBm) cfg80211: Updating information on frequency 5220 MHz for a 20 MHz width channel with regulatory rule: cfg80211: 5170000 KHz - 5250000 KHz @ 40000 KHz), (600 mBi, 2000 mBm) cfg80211: Updating information on frequency 5230 MHz for a 20 MHz width channel with regulatory rule: cfg80211: 5170000 KHz - 5250000 KHz @ 40000 KHz), (600 mBi, 2000 mBm) cfg80211: Updating information on frequency 5240 MHz for a 20 MHz width channel with regulatory rule: cfg80211: 5170000 KHz - 5250000 KHz @ 40000 KHz), (600 mBi, 2000 mBm) cfg80211: Disabling freq 5260 MHz cfg80211: Disabling freq 5280 MHz cfg80211: Disabling freq 5300 MHz cfg80211: Disabling freq 5320 MHz cfg80211: Disabling freq 5500 MHz cfg80211: Disabling freq 5520 MHz cfg80211: Disabling freq 5540 MHz cfg80211: Disabling freq 5560 MHz cfg80211: Disabling freq 5580 MHz cfg80211: Disabling freq 5600 MHz cfg80211: Disabling freq 5620 MHz cfg80211: Disabling freq 5640 MHz cfg80211: Disabling freq 5660 MHz cfg80211: Disabling freq 5680 MHz cfg80211: Disabling freq 5700 MHz cfg80211: Updating information on frequency 5745 MHz for a 20 MHz width channel with regulatory rule: cfg80211: 5735000 KHz - 5835000 KHz @ 40000 KHz), (600 mBi, 2000 mBm) cfg80211: Updating information on frequency 5765 MHz for a 20 MHz width channel with regulatory rule: cfg80211: 5735000 KHz - 5835000 KHz @ 40000 KHz), (600 mBi, 2000 mBm) cfg80211: Updating information on frequency 5785 MHz for a 20 MHz width channel with regulatory rule: cfg80211: 5735000 KHz - 5835000 KHz @ 40000 KHz), (600 mBi, 2000 mBm) cfg80211: Updating information on frequency 5805 MHz for a 20 MHz width channel with regulatory rule: cfg80211: 5735000 KHz - 5835000 KHz @ 40000 KHz), (600 mBi, 2000 mBm) cfg80211: Updating information on frequency 5825 MHz for a 20 MHz width channel with regulatory rule: cfg80211: 5735000 KHz - 5835000 KHz @ 40000 KHz), (600 mBi, 2000 mBm) wl12xx: loaded When I try to bring up the device, I get this: # ifconfig wlan0 hw ether 2a:00:24:01:02:03 # ifconfig wlan0 up wl12xx: firmware booted (Rev 6.3.5.0.98) ADDRCONF(NETDEV_UP): wlan0: link is not ready If I try to scan for an access point, I get nothing: # iw wlan0 scan --- Nothing prints # I also see no additional messages in dmesg.

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
Any ideas at all? Is there some debug info I can get to find out what's going on? Note: I compared the output of 'iw list' from my non-functional system to that of a working one (OMAP4430 PandaBoard) and they are virtually identical, even the line about the antenna... -- ------------------------------------------------------------ Gary Thomas | Consulting for the MLB Associates | Embedded world ------------------------------------------------------------ -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
