Turning wifi on and searching for access point works fine but it fails to connect to any access point.

I marked it invalid for us, if there's some sign that it's a kernel issue please let us know and we'll look again.

Some suggestions for checking on rootfs side:

 - try association with unencrypted AP see if that is any different
 - if there is a wpa_supplicant app in android try running it by hand, with -dd to get debugging info
 - look in the android system logs to see if anything was told there

[vishal (vishalbhoj)]

unencrypted AP works on tracking-panda .

With Encrypted AP wifi is not able to associate even when we try standalone wpa_supplicant from command line :

The relevant logs from logcat :

W/wpa_supplicant( 2109): wlan0: WPA: Failed to set GTK to the driver (alg=2 keylen=32 keyidx=2)
I/wpa_supplicant( 2109): wlan0: RSN: Failed to configure GTK
I/wpa_supplicant( 2109): wlan0: CTRL-EVENT-DISCONNECTED bssid=00:00:00:00:00:00 reason=0

[warmcat (andy-warmcat)]

You need to use wpa_passphrase <ap name> to provide an encrypted passphrase in the config file for that AP... not sure if you did this.

Is it possible that more than one instance of wpa_supplicant is running and treading on each other?

Can you list firmware names and MD5SUM that's in the rootfs in ..../ti-connectivity ?

Do you have more than one Panda running at the same time?

[vishal (vishalbhoj)]

here is the wpa_supplicant.conf file which android maintains and works for stable panda:

ctrl_interface=wlan0
update_config=1
device_name=pandaboard
manufacturer=unknown
model_name=pandaboard
model_number=pandaboard
serial_number=
device_type=10-0050F204-5
config_methods=physical_display virtual_push_button keypad

network={
        ssid="NETGEAR"
        psk="XXXXXXXXXXX"
        key_mgmt=WPA-PSK
        priority=1
}

There is only one instance of wpa_supplicant running .

I attach a tarball in case it's anything to do with anything.

Previously IIRC patches were needed on wpa_supplicant for Android, did that need go away?

You might also try reducing wpa_supplicant.conf to just the passphrase stanza, that's all I had in mine when testing with Ubuntu above.

Andy,

I have tried with the binaries specified by you but it doesn't work. Android is still carrying few patches to wpa_supplicant,but the wifi driver and binary specific to 3.2 kernel works with wpa_supplicant with patches.

It could be something specific to the Android specific patches but shows up only against the tilt tracking kernel.
