Integration of WiFi Module from SAMSUNG based on Atheros AR6003 on R10.3.2 on i.MX53

[ShreeranganathG]

Hi All,

   We have build a custom tablet and are using WiFi module from Samsung SWL-A30H.

- Hardware Interface: SDIO interface

   Please find the log which i am getting when wifi is enabled on the Android Menu

AR6000: configuration opcode 7 is only used for RTOS systems, not Linux systems
AR6K: ** HIF layer does not support scatter requests (17)
wmi_control_rx() : Unknown id 0x101e
Add Filter 0 = 33:33:00:00:00:01
Keep Filter 0 = 33:33:00:00:00:01
Keep Filter 0 = 33:33:00:00:00:01
Add Filter 1 = 01:00:5e:00:00:01
ADDRCONF(NETDEV_UP): wlan0: link is not ready

Software: R10.3.2 SMD BSP customized for custom board

     Please help us in solving the issue.

Thanks and Regards,

The error log is like the following:

D/wpa_supplicant( 2348): ctrl_iface bind(PF_UNIX) failed: Address already in use
D/wpa_supplicant( 2348): ctrl_iface exists, but does not allow connections - assuming it was leftover from forced program termination
D/wpa_supplicant( 2348): Successfully replaced leftover ctrl_iface socket '/data/system/wpa_supplicant/wlan0'
D/wpa_supplicant( 2348): wlan0: Added interface wlan0

This is caused by permission. we should add the following in the init.rc. This bug has been fixed in our newest 53smd software R10.3.2. You can also get it from there.

mkdir /data/system 0775 system system
173 mkdir /data/system/wpa_supplicant 0771 wifi wifi
174 chmod 0771 /data/system/wpa_supplicant

Can you change the debug log level from info to debug in external/wpa_supplicant_ath/wpa_supplicant/main.c? Then recatch the logcat log.

params.wpa_debug_level = MSG_INFO;------------>params.wpa_debug_level = MSG_DEBUG;

Please find the netcfg output and attached the logcat file for the same.

bash-3.2# netcfg

Please review the same and let us know.

The log has no problem.

Please help to get more information through the following:

Firstly, running "netcfg" command in soncole to see if wlan0 net interface is on "up" state.

Secondly, If wlan0 is already on "up" state, please catch whole logcat information to me.
