1.4 XDS110 ETHDR Parts List
The XDS110 ETHDR system consists of the following hardware:
• The XDS110 ETHDR add-on pod
• USB cable (only used for auxiliary power to the ETHDR)
1.5 PCB Breakoff Sections and Compliance
The different sections of the EVM may be broken apart for ease of prototyping and development. Note that
breaking apart the sections voids the warranty. In addition, the stated performance and compliance
specifications of the EVM cannot by guaranteed when sections have been broken apart.
If provided, the shielded USB cable is longer than 3m in length. If not, and one is to be purchased for use
with this EVM, it is required to be no logner than 3m to retain the stated performance and compliance.

2 Probe Interfaces
2.1 USB Power Interface
Additional power for the XDS110 ETHDR add-on is provided through a female Micro-USB B-type
connector. The USB interface provides additional power to the entire system, and no additional
functionality. For target systems drawing more than 400 mA, connect this USB connector to a power
source providing at least 500 mA at 5 V DC.
2.2 Probe Expansion Header
The XDS110 ETHDR interfaces to the XDS110 system through the probe expansion header. The header
exposes a number of functional interfaces of the TM4C129 debug control CPU, as shown in Figure 2. The
use of these signals is reserved for the ETHDR or other add-on modules designed by TI, or designated
third parties.
2.2.1 Physical Connection for the Expansion Interface
The XDS110 ETHDR supports a 30-pin IDC male socket with .100-inch pitch. The signal mapping for this
connection can be found in Figure 2.

XDS110 EnergyTrace™ HDR Debug Probe Add-On
The target power and debug connections are managed through the existing debug and AUX connectors
on the XDS110 Probe. No direct connection between the ETHDR and the debug target exists.
3.2 Basic Setup for the Debug Connection
The presence of the XDS110 ETHDR does not impact the basic debug connectivity of the system, and the
instructions in Section 3.1 of the XDS110 Debug Probe Users Guide (SPRUI94) are still valid.
3.2.1 Probe Supplied Power and ETHDR
The addition of the ETHDR enables the XDS110 Debug Probe to supply current up to 800 mA. No
additional steps are required to support this, and the power configuration steps in Section 3.1.2.2. of the
XDS110 Debug Probe Users Guide (SPRUI94) are still valid.
3.3 Energy Trace HDR
3.3.1 Introduction
When combined with the XDS110 Debug Probe, the XDS110 ETHDR provides an enhanced system that
can be used for measuring the current consumption of the target. These current consumption
measurements can be used to develop power and energy use profiles of the target system. The ETHDR
expands the ET capabilities of the XDS110 Debug Probe, and these may be required for higher current
use cases, or when precise temporal correlation of power transitions is required. Table 1 shows a high
level comparison of the capabilities of the two ET capture types.
Table 1. Base ET and ETHDR Comparison
Capability Base ET on XDS110 Probe ETHDR
Measurement range 500 nA to 100 mA • 1 µA to 120 mA – low current high accuracy
• 1 µA to 800 mA – high current range lower accuracy range
Sampling frequency 2 ksps 256 ksps
Supply ripple Some ripple due to SW DCDC None
3.3.2 Specifications
Other than accuracy and sampling frequency, the specifications for a system utilizing the XDS110 ETHDR
are identical to the ET specifications found in the XDS110 Debug Probe Users Guide (SPRUI94).
3.3.2.1 Accuracy
Table 2 lists the accuracy and range of the ETHDR.
Table 2. ETHDR Measurement Performance
Low Range High Accuracy High Range Low Accuracy
Range Accuracy Range Accuracy
1 µA to 15 µA ±700 nA 1 µA to 70 µA ±3.5 µA
15 µA to 120 mA ±5% 70 µA to 800 mA ±5%
3.3.2.2 Sampling Frequency
The XDS110 ETHDR samples target current consumption a 256k samples per second. Thus, the system
can reliably catch target power transitions that last 10 microseconds or longer.
3.3.3 Hardware Setup
Other than the stacked connection of the XDS110 Probe and the XDS110 ETHDR, the hardware setup is
identical to that which is described in Section 3.1 of the XDS110 Debug Probe Users Guide (SPRUI94).

3.3.4 XDS110 ETHDR Usage in Code Composer Studio
When the XDS110 ETHDR is attached to the XDS110 Debug Probe, the ETHDR is used as the power
measurement system. The procedure for configuring an ET session, capturing, and displaying data are
identical to that defined in Section 3.6 of the XDS110 Debug Probe Users Guide (SPRUI94), with the
exception noted below.
3.3.4.1 CCS Setup for ETHDR
The ETHDR supports two capture ranges, as noted above. The selection changes the size of the shunt
resistor used to measure the target current consumption. The desired range must be specified in the
EnergyTrace Technology Preferences dialog that is reached through CCS →Advanced Tools →
EnergyTrace Technology. Figure 5 shows this dialog, and highlights the selection radio buttons.

3.3.5 XDS110 ETHDR Usage Usage With Command Line Utility – soctune
The Windows-based CCS installation has an interactive command line utility called stune which can be
used for capturing EnergyTrace data to a CSV file. The procedure for using stune is the same as defined
in Section 3.6.5 of the XDS110 Debug Probe Users Guide (SPRUI94), with the addition that the ETHDR
capture range can be specified using the range option –r “lo | hi” with the energytrace command. The “lo”
range selection maps to “Low current, narrower range higher accuracy” and the “hi” range selection maps
to “High current, wider range lower accuracy”. If the range option is not specified, the range is set to “lo”
by default.
