    Hi,

     Can you clarify a few things for me?

    • Before the crash, you were able to flash the program successfully?
    • How did the crash happen? Did you lose power or something while you were trying to load a program in CCS?
    • If you try to load the program again in CCS, what did you see?

    Which debug probe to you have on your board? Depending on which debug probe you have, you may be able to unlock the device to factory setting. In CCS, see below image.

    You can do the same using Uniflash. See below.

    You can also use command line. Go to section 5.3.2. of this app note for detail.

    Hi, 

    Before crash i was able to flash the program there was no problem in flashing.

    The crash has occurred when i selected build all option instead of build project while building.

    It was showing not able to connect to the target.

    Hi,
    The building is only the compilation of the project and it does not involve the programming of the program image into the flash. But you are reporting you are not able to connect which is weird to me. Can you select the project that you want to program and do a 'clean project' first and rebuild the project and then load that program again? If you still have connection issue, can you try with another PC first? If another PC doesn't work either then do I as showed in my last reply to unlock (revert to factory setting) the device.

    Hi,
    Is this issue resolved? Have you tried with another PC and another TM4C device? Have you also tried to unlock the device?
