DK-TM4C129X: I made a mistake in transferring the program, the display turned white, and the board could not be used.

Part Number: DK-TM4C129X

It seems that I transferred the program in the wrong way, the screen turned white, and the board became unusable after that.


Is there a way to get the board back to factory?
Also, is there a way to install the software (Open Weather Map or qs-wearther) that is installed by default?

    Hi,

      What program did you transfer the wrong way? 

      To restore the device to its factory setting you can use the LM flash programmer. See below. 

      The qs-weather example can be found in C:\ti\TivaWare_C_Series-2.2.0.295\examples\boards\dk-tm4c129x\qs_weather.

    I wrote the program without removing the jumper of the J3 connector mounted on the board.
    At that time, I failed to write the program and the screen became white.

    I executed the procedure you taught me, but when I try to write the "qs-weather" program, the error [** ERROR **: Unable to initialize target --0!] Occurs and the program cannot be written. ..
    Is there a solution for this error?

    There is no need to remove J3. Just to clarify one more time, are you using the on-board ICDI debug probe to program/debug the MCU?

    Also to clarify again one more time, was it working at one point of time that you could program and debug the device until you modified the program?

    Did you really unlock the device successfully? Did you follow the steps to perform the unlock operation?

    1. Un-power the board and press reset

    2. Power the board but do not release the reset

    3. Run the unlock sequence according to the LM programmer "dialog box"

    4. Power Cycle the board

    5. Do a Flash Erase Check or load a simple program to confirm the debugger can access the MCU again.

    I was able to recover by following the procedure I was taught.
