    'Permission denied' errors are generally due to incomplete/incorrect setup in init.rc.

    Are you trying this on omap3evm or a custom device? I recommend that you compare init.rc for your device with init.rc for AM37x provided with the TI Android Devkit v2.2 for Froyo.

    BTW, please ask Android questions at the Android e2e forum @ e2e.ti.com/android

    Thanks. This permission issue is solved by (1) By loading the NVS_MAP.bin file and (2) Moving the RFS from the NFS to Flash card. Now WiFi interface is up, able to see the list of APs and able to transmit packet with (80%) loss.
