Problem to load code to TIVA TM4C123GH6PM (Tiva C series LaunchPad) in IAR 6.50

I tried to start debug the Tiva Launchpad board with example project in IAR 6.50 but I got following messages:

I see the uploading progress bar, it full up to 100% but then look like hang. As I see in log message communication with board do not succesfull. Can anybody help me?

    Hi Tankist,

         If any of your launchpad example program works, then that IAR example project, probably is not meant for the Tiva Launchpad.

    The problem is not in the project from the example, the problem is to download code to the processor (either my own or from the example). This is probably due to incorrect configuration files of TivaWare, because if I point out the type of processor LM4F230H5QR (which is a complete analog) and use StellarisWare, all loaded and working properly.

    Tankist,

    Try updating to the latest IAR and see if that problem goes away, I have a feeling it will. Also worst case scenario you could use the LMFlash Programmer tool that we provide to upload the code to the board.

    While in general TI Austin's, "update to latest/greatest" proves sound - perhaps not this time.

    Ours is paid IAR - and updated to ver 6.60.2.5507.   And this critical bit reveals:

    Unstated is whether JLink (JTAG probe) or PC to launchpad (via USB) is connection medium.  Note the yellow highlight - appears TI Stellaris is the only means (presently) to attempt to attach - if you are w/out JLink.

    Suspect the issue may be the (possible) new ICDI MCU employed under rebrand.  Or not - but perhaps worthy of consideration...

    After the IAR updating to 6.60 everything looks good, the project is downloaded into the board and executed.

    How do you get the IAR-compiled C code onto the Launchpad?  That minor detail doesn't seem to be mentioned anywhere I've found.
