TM4C1290NCPDT: XDS 10 pin adapter

This is using a custom board with a 10 pin ARM debug connector & 25MHz crystal.  Currently I have used a ulink2 successfully over multiple boards so I do not believe it is a board problem.

Using UniFlash I get this error using either the XDS110 or XDS200:

[ERROR] CS_DAP_0: Error connecting to the target: (Error -1170 @ 0x0) Unable to access the DAP. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 9.3.0.00042)

I've tried holding in reset and a few other configuration changes but it will not work. 

CCS generates this error:

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.

I believe the problem is that the XDS110 and XDS200 connector is not the same as the ARM 10 pin connector.  Both debuggers come with "20-pin to ARM 10-pin adapter" (516441 Rev A) but I cannot find any documentation about the adapter.  Certainly the XDS 20 pin pinout is not the same as ARM - the key on pin 6 indicates that.

A quick look at the "20-pin to ARM 10-pin adapter" looks like the NRST pin is not connected - there are some empty jumper positions on the bottom.  But again without documentation I do not know if this is the problem.
