wlan_cu gets can't connect the socket

Hi,

could ypu please let me know which version are you using?

for linux the bringup sequence is:

insmode sdio.ko (that not always needed - depends on the verion you use)

insmode bmtrace.ko (that not always needed - depends on the verion you use)

insmode tiwlan_drv.ko

./tiwlan_loader

ifconfig tiwlan0 192.168.1.10 netmask 255.255.255.0 up

Now the Driver will come up and then operate the supplicant by:

./wpa_supplicant -Dwext -itiwlan0 -c wpa_supplicant.txt &

./wlan_cu

Hi Eyal,

i'm using prebuilt filesystem of DM37x from TI_Android_FroYo_DevKit-V2.2.tar.gz.

i found that there is no need to(and cann't) insmod sdio.ko: 

# insmod  /system/etc/wifi/sdio.ko 

# insmod  /system/etc/wifi/bmtrace.ko 

# insmod  /system/etc/wifi/tiwlan_drv.ko 

tiwlan_drv: exports duplicate symbol g_sdio_debug_level (owned by sdio)

insmod: init_module '/system/etc/wifi/tiwlan_drv.ko' failed (Exec format error)

# rmmod sdio

# insmod  /system/etc/wifi/tiwlan_drv.ko 

TIWLAN: driver init

#

And i cann't start wpa_supplicant by directly run the command(why?), but only start it as a service:

# wpa_supplicant -Dtiwlan0 -itiwlan0 -c/data/misc/wifi/wpa_supplicant.conf -dd &

# TIWLAN: 1832.439290: wlanDrvIf_Open()

mkdir[ctrl_interface]: Permission denied

TIWLAN: 1833.460099: wlanDrvIf_Release()

[1]+  Done(255)                  wpa_supplicant -Dtiwlan0 -itiwlan0 -c/data/misc/wifi/wpa_supplicant.conf -dd

# 

# wpa_supplicant -Dwext -itiwlan0 -c/data/misc/wifi/wpa_supplicant.conf -dd &

# TIWLAN: 1850.805135: wlanDrvIf_Open()

mkdir[ctrl_interface]: Permission denied

TIWLAN: 1851.820972: wlanDrvIf_Release()

[1]+  Done(255)                  wpa_supplicant -Dwext -itiwlan0 -c/data/misc/wifi/wpa_supplicant.conf -dd

# start wpa_supplicant 

# TIWLAN: 1875.506002: wlanDrvIf_Open()

#

another thing, can you tell me what does the option -D mean? my netcfg outputs:

# netcfg

lo       UP    127.0.0.1       255.0.0.0       0x00000049

eth0     UP    192.168.0.110   255.255.255.0   0x00001043

tiwlan0  UP    0.0.0.0         0.0.0.0         0x00001043

Hi,

I requested someone that has more experience with Android to answer, so you should get a follow-up answer early this week

Now there is something that got me more confused. ddms show the following messages:

01-01 01:39:31.437: ERROR/WifiHW(969): Cannot access "/data/misc/wifi/wpa_supplicant.conf": Permission denied

01-01 01:39:31.437: ERROR/WifiHW(969): Wi-Fi will not be enabled

while my /data/misc/wifi/wpa_supplicant.conf is:

# ls -l /data/misc/wifi/

drwxrwx--- wifi     wifi              2011-04-19 09:46 sockets

-rwxrwx--- wifi     wifi          134 2011-04-20 08:48 wpa_supplicant.conf

and sometimes it is possibe to enable Wi-Fi. but got another issue:

01-01 05:48:29.781: ERROR/WifiHW(1009): Unable to open connection to supplicant on "tiwlan0": Permission denied

01-01 05:48:34.781: ERROR/WifiHW(1009): Unable to open connection to supplicant on "tiwlan0": Permission denied

while /dev/socket/wpa_tiwlan0 shows:

srwxrwxrwx wifi     wifi              2000-01-01 02:54 wpa_tiwlan0

Please try changing the permissions for wpa_supplicant.conf and wpa_supplicant

cd /data/misc/wifi

chmod 777 wpa_supplicant.conf

cd /system/bin

chmod 777 wpa_supplicant

Thanks

Saurabh

Hi Saurabh,

I changed permissions of everything asosiated to 777 in init.rc and reboot it:

    chmod 0777 /system/etc/wifi

    chmod 0777 /system/etc/wifi/wpa_supplicant.conf

    chown wifi wifi /system/etc/wifi/wpa_supplicant.conf

    mkdir /data/misc/wifi 0777 wifi wifi

    mkdir /data/misc/wifi/sockets 0777 wifi wifi

    chmod 0777 /data/misc/wifi

    chmod 0777 /data/misc/wifi/wpa_supplicant.conf

    chown wifi wifi /data/misc/wifi

chown wifi wifi /data/misc/wifi/wpa_supplicant.conf

service wpa_supplicant /system/bin/wpa_supplicant -Dtiwlan0 -itiwlan0 -c/data/misc/wifi/wpa_supplicant.conf -dd

    socket wpa_tiwlan0 dgram 777 wifi wifi

    disabled

    oneshot

But it still says "Unable to open connection to supplicant on "tiwlan0": Permission denied"! what else can i do?

BTW, at first I'm using prebuild filesystem of DM37X of Android froyo, and then i build android gingerbread myself. I download and build Android filesystem using rowboat-gingerbread-dsp.xml and did no change to the source code. They all have this issue. 

I know it's unbelievable, but I suggest you do this youself and you'll know how strange it is.

There are lot of variables here. Please run he following commands and let me know the ouput -

cd /system/etc/wifi
insmod tiwlan_drv.ko
start wlan_loader
ifconfig tiwlan0 192.168.0.101 netmask 255.255.255.0 up
start wpa_supplicant
wlan_cu -itiwlan0

Please let me know the output for each step.

Thanks

Saurabh

Hi Saurabh,

I think I've followed your steps everytime!

I just do this again, here is the outputs:

# cd /system/etc/wifi

# insmod tiwlan_drv.ko

TIWLAN: driver init

# start wlan_loader

# init: starting 'wlan_loader'

init: waitpid returned pid 994, status = 00000000

init: process 'wlan_loader', pid 994 exited

# ifconfig tiwlan0 192.168.0.101 netmask 255.255.255.0 up

puyou lu,

Seems like you do not have root access on the shell. Try command "su" or any root access command that your platform supports. Thanks
