Other Parts Discussed in Thread: TM4C123GH6PM

Sir

             I am using TIVA Launchpad TM4C123GXL. While working in Win 7 I have not find any problem with my launchpad. But Now I have installed CCS V5 in Win XP 2 and also tivaware in my PC.

         I have wrote a program for blinking LEDs in the Launchpad built without error. But while writing to Flash an error is coming, "error connecting to the target : Frequency is out of range " in a popup window with heading "Stellaris In Circuit Debug Interface/CORTEX_M4_0"

Please guide me to get out of this problem

thanking you

    Hi Prasanth,

    Check your "Device Manager" for the drivers to be installed properly or not. If you observe a yellow alert signal in front of the Launchpad driver then there is some issue while loading the drivers.

    Regards,

    If it does turn out to be a driver installation issue as pointed out by Gautam, you can refer to this post for more information on reinstalling the drivers.

    When you insert you kit, check for emulator version in device manager as follows:

    Hi Thiva,

         Have you made your launchpad work before to any example programs? There should be a readme first file for this launchpad that will guide you to run the pre-loaded example program.

    Connect your Tiva launchpad to your PC and post a picture of you Device Manager here. If you have not installed the Stellaris ICDI drivers, download from the TI website and install the drivers.
