OMAP3530 evm - Wlan driver problem

Yusuf CERI

Other Parts Discussed in Thread: WL1271, OMAP3530

I have OMAP3530 evm, I want to use android wlan and bt properties. I downloaded TI Android FroYo DevKit V2.2 sources and I used WL1271_Linux_SDK 3_00_01_06 packed using WL1271 Android patches. while building wlan drivers I received some warnings but building was completed successfully. Then I copied created modules to the file system. I run android and I enabled wifi from menu but I received "failed to load wi-fi driver" error. I can't see wlan interface from adb. Otherwise Blutetooth is working.
What is the reason of this problem?

Are you able to load the wlan driver through command line? Try this..

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

I tried but I wasn't able to load,

# 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)

I assume that you are following the porting guide at http://processors.wiki.ti.com/index.php/Android_wireless_build_and_porting_guide

Can you verify in your init.rc file to see if this line is commented out (or not present)

insmod /system/etc/wifi/sdio.ko

In early test versions, two kernel modules were used for WLAN: sdio.ko and tiwlan_drv.ko. I'm wondering if you are using that. The updated method requires only tiwlan_drv.ko
