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

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.

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?
