Hello,

I am using LM4F232 and cc3000 module to bring Basic Wi-Fi device up.

When i debug,  at code point      MAP_SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOG); in Basic_wifi_application.c, i am getting this message

Can't find a source file at "C:/cygwin/sandbox/DriverLib/build/DriverLib.test/driverlib/sysctl.c"
Locate the file or edit the source lookup path to include its location.

What is the problem?

Regards

cc3000 cc300

    Hello,

    What toolchain and OS are you using?  The file in question is part of the Stellarisware library and should be installed in the default directory C:\StellarisWare (assuming windows).

    Hi Nikit,

    It seems like a stellaris environment issue.
    I suggest that you'll open a post in the stellaris general discussion forum.

    Thanks,
    Alon.S

    I feel so there is no interrupt handler routine in spi.c when tSLInformation.WriteWlanPin( WLAN_ENABLE ); is called.. 

    Please let me know..

    Hi,

    Are you using external power directly to the module as in the instructions?

    Hi,

    It is recommended to use external power directly to the module (3.3V)with Stellaris LM4F232H5QD.

    The board doesn't supply enough power to the module, therefore CC3000 can't turned on and you will stay stuck at wlan_start(0).

    All this information is in our wiki page plus explanation on how to connect the power to the module:
