[FAQ] CCS/LAUNCHXL-F280049C: Issues with LAUNCHXL-F280049C and XDS110

Part Number: LAUNCHXL-F280049C
Other Parts Discussed in Thread: C2000WARE

Tool/software: Code Composer Studio

Hello, I've recently bought a Launchxl- F280049c launchpad from TI. I am trying to Flash example code from C2000-device support present in C2000ware but I am unable to do so. 

I am getting the following error-   

The version of CSS installed---- Version: 8.3.0.00009 

I've tried to Test the connection from VERIFY option in properties and got the following script.-

[Start]

Execute the command:

%ccs_base%/common/uscif/dbgjtag -f %boarddatafile% -rv -o -S integrity

[Result]


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

The scan-path will be reset by toggling the JTAG TRST signal.
The controller is the XDS110 with USB interface.
The link from controller to target is direct (without cable).
The software is configured for XDS110 features.
The controller cannot monitor the value on the EMU[0] pin.
The controller cannot monitor the value on the EMU[1] pin.
The controller cannot control the timing on output pins.
The controller cannot control the timing on input pins.
The scan-path link-delay has been set to exactly '0' (0x0000).

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

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

The value is '-233' (0xffffff17).
The title is 'SC_ERR_PATH_BROKEN'.

The explanation is:
The JTAG IR and DR scan-paths cannot circulate bits, they may be broken.
An attempt to scan the JTAG scan-path has failed.
The target's JTAG scan-path appears to be broken
with a stuck-at-ones or stuck-at-zero fault.

[End]

would like to know, how I can repair this error!. Is my Board damaged??

  • Archit,

    Please see the LauncPad User's Guide:

    www.ti.com/lit/spruII7

    On page 25:

    Ensure that the target configuration is set up to use cJTAG in 2-pin advanced mode.
    Open the Target Configuration file (.ccxml) in Code Composer Studio. Click on the Advanced
    tab and select cJTAG (1149.7) 2-pin advanced modes from the drop-down labeled
    JTAG/SWD/cJTAG Mode. Leave the Target Scan Format as OSCAN2 format.

    I hope this helps. If this answers your question, please click the green "Verified Answer" button. Thanks.

  • I read the Guide and made the above-mentioned changes 

    I performed test connection and still getting the same issue--

    I checked my device manager and found XDS110 Class Application/User UART listed-

    Please help me identify the issue so I can get started with the launchpad.
