TMS570LS04x LaunchPad and Windows 8.1

Trying to run "Demo Suite Launcher", it reports: "Demo software not detected on microcontroller. .... Would you like to program the demo software into the microcontroller's flash memory now?"

If I click "Yes", Demo says "Now Programming...", the LP's LED "D8" lights and appears to flicker for a few minutes then goes off and nothing else happens and Demo Suite Launcher has to be killed in task manager.

Every executable in the Safety Demo folder has been set to WinXP SP3 compatibility and "Run as Administrator".

Pressing "POR RESET" does nothing as well.

If I build the project in CCS 5.5, it will work, 'sort of'- LED "D10" lights, but when I try to run the demo it says the firmware is not installed and prompts to install it, even if I close CCS, disconnect the LP, then reconnect the LP and run the Demo.

    Strange thing is task manager reports the Demo launcher is using near 1% of the CPU, and this is a Core 2 Quad 8200.

    Started the demo directly, bypassing the launcher after uploading the project from within CCS.

    Demo said something about lost communications, similar to http://processors.wiki.ti.com/index.php/Hercules_LaunchPad:_Safety_Demo

    I exited the demo, and restarted as suggested and had a blue-screen and had to reboot- first time I've had a blue screen on this computer in over a year.

    Let the demo launcher run, which was started just after the previous post (and I notice the time isn't my zone so keep it relative) and after selecting to update the firmware since that wasn't loaded, it popped a dialog box again (not sure when but within the last 1 hour & 30 minutes), saying that the firmware wasn't loaded and asked if I wanted to install it.

    Loading via the demo program or nowflash doesn't work for me either.

    what worked:

    in ccsv5, when in debug mode, pause and load the precompiled binary file via the load menu. The binary file is in the tms570ls04x subdir of the security demo install.

    Or

    in ccsv5, import the project located in that same tms570ls04x subdir, modify the build steps so that the path to your version of the ecc loader version is correct. Compile and debug And start.

    only start the demo program after the launchpad is running the uploaded program.

    good luck.
