Discussion created by Swaraj vutturi on Jun 6, 2012
Hi,  I am building android 4.0.4 for imx53 board. I'm stuck with wifi porting issue. I'm able to scan and connect using command prompt, but i'm unable to use GUI for wlan0 and not able to start supplicant properly with GUI.  The following is the error message:   D/NetworkManagementService( 1144): Registering observer I/WifiService( 1144): WifiService starting up with Wi-Fi enabled I/WifiHW ( 1144): ************* wifi.c insmod is called********** I/ethernet( 1144): User ask for device name on 0, list:B7F740, total:2 I/ethernet( 1144): User ask for device name on 1, list:B7F740, total:2 I/WifiHW ( 1144): ************* wifi.c insmod is called********** D/NetworkManagementService( 1144): rsp <213 00:23:a7:00:01:58 0.0.0.0 0 [down broadcast multicast]> D/CommandListener( 1066): Setting iface cfg D/CommandListener( 1066): Trying to bring down wlan0 D/CommandListener( 1066): broadcast flag ignored D/CommandListener( 1066): multicast flag ignored D/NetworkManagementService( 1144): flags <[down broadcast multicast]> E/WifiHW ( 1144): ctrl_interface is = /data/misc/wifi E/WifiHW ( 1144): Unable to open connection to supplicant on "wlan0": E/WifiHW ( 1144): Unable to open connection to supplicant on "wlan0": No such file or directory E/WifiHW ( 1144): Unable to open connection to supplicant on "wlan0": E/WifiHW ( 1144): Unable to open connection to supplicant on "wlan0": No such file or directory W/EthernetStateMachine( 1144): Could not stop DHCP I/EthernetSta[ 66.122325] init: no such service 'dhcpcd_sit0:-h android-45fe3c772cef2905 sit0' teMachine( 1144): trigger dhcp for device sit0 I/SystemServer( 1144): Throttle Service E/WifiHW ( 1144): Unable to open connection to supplicant on "wlan0": E/WifiHW ( 1144): Unable to open connection to supplicant on "wlan0": No such file or directory I/SystemServer( 1144): Backup Service D/dalvikvm( 1144): GC_CONCURRENT freed 182K, 4% free 8037K/8327K, paused 3ms+47ms I/SystemServer( 1144): SamplingProfiler Service E/WifiHW ( 1144): Unable to open connection to supplicant on "wlan0": E/WifiHW ( 1144): Unable to open connection to supplicant on "wlan0": No such file or directory I/SystemServer( 1144): NetworkTimeUpdateService I/WindowManager( 1144): SAFE MODE not enabled W/RecognitionManagerService( 1144): no available voice recognition services found E/WifiHW ( 1144): Unable to open connection to supplicant on "wlan0": E/WifiHW ( 1144): Unable to open connection to supplicant on "wlan0": No such file or directory D/dalvikvm( 1144): GC_CONCURRENT freed 252K, 4% free 8311K/8647K, paused 5ms+5ms I/ActivityManager( 1144): Start proc org.linaro.wallpaper for service org.linaro.wallpaper/.LogoWallpaper: pid=1236 uid=10019 gids={} W/InputManagerService( 1144): Ignoring setImeWindowStatus of uid 1000 token: null E/WifiHW ( 1144): Unable to open connection to supplicant on "wlan0": E/WifiHW ( 1144): Unable to open connection to supplicant on "wlan0": No such file or directory E/WifiStateMachine( 1144): Failed to setup control channel, restart supplicant I/ActivityManager( 1144): Start proc com.android.inputmethod.latin for service com.android.inputmethod.latin/.LatinIME: pid=1248 uid=10028 gids={} D/SystemUIService( 1221): loading: class com.android.systemui.statusbar.tablet.TabletStatusBar D/SystemUIService( 1221): running: com.android.systemui.statusbar.tablet.TabletStatusBar@4112ff98 sms: com.android.providers.telephony.MmsSmsProvider I/Process ( 1144): Sending signal.
