TMDX570LS12HDK Development kit stopped to co-operate

Other Parts Discussed in Thread: TMS570LS1227

I try to evaluate TMS570LS1227 using a TMS570LS12x/11x Hercules Development Kit that I received a couple of days ago.

At first the board worked ok i.e. I managed to launch demo SW and even to execute my own dummy application. But then the board stopped to co-operate with me: Flashing seems to be not working anymore. I can't upload my own application or demo SW.

If I start Hercules Demo Suite Launcher it says:

- "TMS570LS12x HDK Board Detected"

- "nowFlash has encountered an error while programming the device. Please ensure that the device is correctly connected and then try running the demo again."

Power cable is connected. USB cable is connected and the device is registered to PC (verified from Win device manager).

Is this a "known issue" ? ... anything I could try to do?  (yes, I have rebooted PC already)

Or could the HW board be just broken? 

This failure showed up first time during the debugger session without touching the board.

    Hello,

    Can you try erasing the flash using nowFlash? You may have to hold the reset button down, execute the nowFlash erase command via the GUI, and then release the reset button when nowFlash tries to connect to the CPU (halt it).

    Once you are successful in erasing the part, you can download the demo code again and then check if JTAG connection is okay. This is typically caused by the code inside the part causing an exception that is a higher priority than a debug mode entry request from a debugger.

    Regards, Sunil

     Thanks for your advice ... unfortunately it seems to be not helping.

    I executed nowFlash command (copied from GUI) through the command prompt so that I managed to copy error message:

    C:\ti\nowFlash\v3.42.3>nowFlash.exe -er -emu TIXDS100V2 -p 000 -cpu CORTEX_RXX -targets 1
    nowFlash version 3.42 Build (OFFICIAL)
    Config file C:\ti\nowFlash\v3.42.3\nowFlash.cfg Revision: 3
    Port address 0x000 target..initialize..connect....failed
    Error 199 - Unable to connect to target on port address 0x000.
    **************************************************************
    Emulator drivers compatible with CCS 2.21 and later contain
    a 'TRG_connect' function for connecting to the target after
    initialization. If you see this error, check to make sure
    all connections from the PC to the DUT are correct and the
    DUT power levels and clock frequency are within specification.

    You may need to use the tools provided by the emulator
    vendor to determine the layout of the scan chain and generate
    a custom board configuration. Contact the emulator vendor
    for more information.
