Problem with connecting 138/C6748 to CCS v5.2.1

Other Parts Discussed in Thread: TMS320C6748

Problem:

I have a TI C6748 Development Kit,  I am also running CCS v5.2.1, I am unable to connect the board to CCS.  I have tried different emulators including TI, 

Texas Instrument Simulator

C674x CPU Cycle Accurate Simulator, Little Endian

Texas Instrument  XDS100v2 USB Emulator

LCDKC6748 , TMS320C6748 , EVMC6748 

I have installed FTDI drivers as well.  one more thing,  the DSK board comes with a finger print example that works fine (which means the computer is connected with the board and interacts with the Tera Term, its just not connecting to CCS.  

Everytime I get the error below:

[Start]

Execute the command:

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

[Result]


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

C:\DOCUME~1\NIPINM~1\LOCALS~1\APPLIC~1\.TI\
1078663705\0\0\BrdDat\testBoard.dat

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

This utility has selected a 100- or 510-class product.
This utility will load the adapter 'jioserdesusbv3.dll'.

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 '-151' (0xffffff69).
The title is 'SC_ERR_FTDI_OPEN'.

The explanation is:
One of the FTDI driver functions used during
the connect returned bad status or an error.
The cause may one or more of: invalid emulator serial number,
blank emulator EEPROM, missing FTDI drivers, faulty USB cable.
Use the xds100serial command-line utility in the 'common/uscif'
folder to verify the emulator can be located.

[End]

I will add a little bit of my experience:

I have used Spectrum Digital board TMS320C6713 DSK with CCSv3.1, CCSv5.02, CCSv5.2.0, CCSv5.2.1, and SD board seems to work fine with everything.

I can connect, program, stop, start, reset, and see my results.

    If you're trying to connect to a board then you should not use the "simulator" configuration.  If you're using the JTAG that's built into the board then you should choose the XDS100v2 as your emulator and c6748 as your board.  Note that there are two different USB ports on the board.  One of the USB ports connects directly to the USB peripheral of the 6748 (don't use that one for JTAG by mistake!!!).  The other USB port connects to the FTDI chip for the XDS100v2 function.  Take a look in your device manager and make sure you can see the XDS100v2 emulator and/or FTDI chip in there (sorry, I forget exactly how it shows up off the top of my head).

    Mr. Griffis, Thank you for your response. Are you sure that L138/C6748 Dev board, I mentioned above comes with a XDS100 built in.  Nowhere in the documentation I could get any information about the inbuilt XDS.  As a matter of fact it has a JTAG connector for XDS.  I want to make sure that I have explored all possible ways of connecting DSK to CCS before I go and purchase another piece of hardware (XDS100v2) which is not required in the first place.  

    For the connection it shows USB COM port 3 in the Device manager.

    What board are you using and what JTAG?  You mentioned only "a development kit" which I assumed to be our EVM which has built-in emulation.  Now that I think about it, I believe those EVMs came out before XDS100v2, i.e. I believe the built-in emulation is in fact simpy XDS100.  Is that your issue?

    My issue is that the board (TMS320C6748 DSP Development Kit(LCDK)) is directly connected from USB to PC, but does not connect to CCS.  I am using the USB with FTDI chip.  I have also downloaded and installed FTDI drivers.  I have tried different setting on CCS (CCXML settings) using XDS100v1/2/3 but it still give me the error that I pasted above.  My only concern is that do I require XDS (external module connects with onboard JTABG to USB of PC ) or is the module built in accessed via USB.

    LCDK does not have integrated JTAG.  The FTDI chip is a UART-to-USB converter.  It's taking the UART signals from the c6748 and converting to USB so you can easily plug it into a PC.  You will need external JTAG such as XDS100v2 for debug.

    Thank you, thats all I wanted to know.
