TMS320C6670 - Blackhawk XDS560v2 USB Problem

Other Parts Discussed in Thread: TMS320C6670

Hi all;

I configured my board (TMS320C6670 - evaluation module) with necessary emulator drivers and debugged a simple program on it. But today when I powered on the board, pc could not communicate with the emulator. And LEDs on the integrated emulator also seems to be not working. 

What can be the cause ? I read on the forum that 10 consecutive power-offs may cause to make emulator go safe-mode. But I am also not able to see the emulator in Blackhawk Config Utility. Can there be a problem about power goes to the emulator ?

Thanks in advance.

    Hi Haken,

    Please provide below information.

    1. CCS Version?

    2. Have you tested the connection using "Test Connection" option?

    3. Please provide the log of error.

    Thanks.

    Hello Hakan,

    Are you referring to the the Blackhawk XDS560v2 Mezzanine card?

    In any case, if there is an issue with PC<->emulator communication, it could be an issue with the emulator HW. Did you try the emulator with another PC?

    Thanks

    Hi Rajasekaran,

    CCS version is 5.5

    Test Connection output is :

    [Start]

    Execute the command:

    %ccs_base%/common/uscif/dbgjtag.exe -f %boarddatafile% -rv -o -F inform,logfile=yes -S pathlength -S integrity

    [Result]


    -----[Print the board config pathname(s)]------------------------------------

    C:\DOCUME~1\ADMINI~2\LOCALS~1\APPLIC~1\.TI\
    213602635\0\0\BrdDat\testBoard.dat

    -----[Print the reset-command software log-file]-----------------------------

    This utility has selected a 560/2xx-class product.
    This utility will load the program 'bh560v2u.out'.
    E_RPCENV_IO_ERROR(-6) No connection: emulator was not found
    Download failed for file C:\ti\ccsv5\ccs_base\common\uscif\xds560v2.out

    An error occurred while soft opening the controller.

    -----[An error has occurred and this utility has aborted]--------------------

    This error is generated by TI's USCIF driver or utilities.

    The value is '-250' (0xffffff06).
    The title is 'SC_ERR_ECOM_EMUNAME'.

    The explanation is:
    An attempt to access the named emulator via USCIF ECOM has failed.

    [End]

    Hi Ki-Soo,

    Yes I am referring to Blackhawk XDS560v2 Mezzanine card.

    I did not have tested it with another PC. But it was OK with the current PC before.

    My concern is none of LEDs seem to be working at all so there may be a problem with the emulator.

    D3 on the emulator should first light up when you provide power to your board. Then D1 and D2 (with D3 turning off).

    If none of the LEDs ever light up, it does seem like a HW problem with the emulator. Look for any outward problems like bent pins on the connector and such. I've had an problem where L2 was physically broken and required some soldering work. You can also try contacting Blackhawk for some suggestions.

    I understand thanks.

    My other question, is there also another emulator on board ? When I plug into the usb on the board, I can see TI XDS100 CHANNEL A and TI XDS100 CHANNEL B in device manager. But I cant connect to it from CCS.

    Yes there is an XDS100v2 on the EVM itself. You can use that to connect to the target.

    My mistake, it is an XDS100v1.
