Other Parts Discussed in Thread: AM3517

I am planning ro use wifi on AM3517 , the OS is Android FroYo, Now I have downloaded the firmware into wifi module, but when start to scan the network, it could not scan any networks.Then it will unload the driver of wifi from OS.  Is anybody know why? The following message is from the console when I turn on the wifi on seetings.

    Can you also paste the relevant portions from the logcat output?

    Something appears to have caused the driver to stop

    Perhaps your init.rc is not seup fully for wlan

    Have a look at the init.rc for omap3evm in the TI Android DevKit v2.2 to see how wifi is setup for omap3evm rev G

    here's the direct link for the community version http://gitorious.org/rowboat/vendor-ti-omap3evm/blobs/rowboat-froyo/init.rc
