XDS-200 connection error.

I've to connect XDS-200 emulator to a tiva-C series ARM Cortex M4 microcontroller. The target side connector is ARM-10 and emulator side connector is TI-20. I connected TDI, TDO, TMS, TCK and nReset pins as specified. I've the following error received on Test Connection with CCS Studio.

[Start]

Execute the command:

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

[Result]

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

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

This utility has selected a 560/2xx-class product.

This utility will load the program 'xds2xxu.out'.

The library build date was 'Aug 20 2013'.

The library build time was '23:33:52'.

The library package version is '5.1.232.0'.

The library component version is '35.34.40.0'.

The controller does not use a programmable FPGA.

The controller has a version number of '12' (0x0000000c).

The controller has an insertion length of '0' (0x00000000).

This utility will attempt to reset the controller.

This utility has successfully reset the controller.

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

This emulator does not create a reset log-file.

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

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

The value is '-235' (0xffffff15).

The title is 'SC_ERR_PATH_DR_BROKEN'.

The explanation is:

The data scan-path cannot circulate bits, it may be broken.

An attempt to scan the JTAG data registers has failed.

The target's JTAG data path appears to be broken

with a stuck-at-ones or stuck-at-zero fault.

[End]

I don't have external pull ups to TDI, TDO. Is that the problem. Else What?
