    May be bit hard to erase ROM - n'est pas, mon ami?

    As to somehow - suspect that "someone" (i.e. perpetrator) resides - this issuing thread.  (he's sure to know)

    Might the original file(s) be listed w/in one of the User Guides which accompany your board?  (or are always on-line)  Reloading that code into Flash (not ROM) should return your board to original functionality.  (until someone - somehow - wreaks next havoc...)

    Hello Jam,

    The default program on the DK-TM4C129 is in Flash and not the ROM. You cannot restore the same if it is erased but now could load any other program for TM4C129 using IDE's like CCS, Keil, etc.

    do remember to select the Debugger as Stellaris ICDI

    Regards

    Hi,

       Maybe you are not powering up your DK-TM4C129x correctly. If your DK is fresh out of the box, most likely the example program is there. See, Getting Started Guide and ReadMe First links below.

       If there are really no pre-loaded application at your DK, then you can load qs_weather using LM Flash Programmer or by using your IDE.
