    Hello Taekin,

    Did you try to program the DK-TM4C129X board using LMFlash Programmer?

    If yes, then please share if that was successful.

    If no, then try to program an existing binary from TivaWare into DK-TM4C129X board, using LM Flash Programmer. LM Flash Programmer can be downloaded from www.ti.com/.../lmflashprogrammer.

    Also share the "Debug Configuration" that is being used when you start debug.

    If you starting new development, then I would recommend that you use the latest version of TivaWare and CCS.

    Thanks,
    Sai
