CCS/TMDSLCDK6748: Having trouble getting started

Part Number: TMDSLCDK6748
Other Parts Discussed in Thread: TMS320C6748

Tool/software: Code Composer Studio

What am I doing wrong?

I have an TMDSLCDK6748 and a Olimex TMS320-XDS100-V3

I've got a 14 pin ribbon cable between the TI_JTAG_14 port on the XDS100 and the J6 JTAG port on the TMDSLCDK6748.

I have opened the ARM_JTAG_E jumper on the XDS100.

I'm using Code Composer Studio 5.1.1.00031

In my NewTargetConfiguration.ccxml window I've selected  "Texas Instruments XDS100v3 USB Emulator" and "tms320c6748".

When I "Test Connection", I get:

[Start]

Execute the command:

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

[Result]


-----[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'.
The library build date was 'Dec 19 2011'.
The library build time was '21:32:12'.
The library package version is '5.0.569.0'.
The library component version is '35.34.39.0'.
The controller does not use a programmable FPGA.
The controller has a version number of '4' (0x00000004).
The controller has an insertion length of '0' (0x00000000).
This utility will now attempt to reset the controller.
This utility has successfully reset the controller.

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

The scan-path will be reset by toggling the JTAG TRST signal.
The controller is the FTDI FT2232 with USB interface.
The link from controller to target is direct (without cable).
The software is configured for FTDI FT2232 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 occurred while hard 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 '-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]

I have verified with o'scope that TRST goes low.

I have verified pinouts on both devices and cabling looks right.

Here's some XML I don't quite understand:
