Facing UART  connection problem:

when I tried to do one of the workshop programs on UART in Tivaware Launchpad.

I m getting following errors in debug mode:

ComPort: File Loader: Verification failed: Target failed to write 0x00000000

    Hello Sudharsan,

    There is not a lot of detail here to work with. Help provide more background please:

    Do you see any compile errors with the code?

    What version of CCS are you using?

    Are you just using device Debug? Because those messages do not look familiar to me for a typical CCS Debug Session. If not doing a Debug session in CCS, explain what you are doing please.

    Have you been able to load other example projects to the LaunchPad?

    Hello Sudharsan,

    I haven't heard back from you, so I’m assuming you were able to resolve your issue.

    I will close this thread now, but if you have not solved this issue then post a reply below (or open a new thread if the thread has locked due to time-out).
