MSP Debuggers
5.1
MSPDebugStack
The
is the host side interface to all MSP debug probes. It is a library for controlling and
debugging Texas Instruments MSP ultra-low power microcontrollers during software development phase.
For this purpose the MSP microcontroller is controlled by the MSPDebugStack using the MSP device's
JTAG interface. The MSPDebugStack provides device control (for example, run and stop), memory
programming and debugging functionality (for example, breakpoints).
The MSPDebugStack supports these operating systems:
•
Windows 10 32-bit or 64-bit
•
Windows 8 32-bit or 64-bit
•
Windows 7 32-bit or 64-bit
•
Ubuntu 32-bit or 64-bit
•
CentOS™ 6 64-bit
•
CentOS 7 64-bit
•
OS X 64-bit
The debug probe firmware for all field updatable tools is included in the MSPDebugStack. It automatically
detects if an update of the debug probe is required.

Ultra-Low-Power (ULP) Debug Support
ULP debug support enables users to debug in the low-power modes that are used in their application
software.
If this option is enabled during an active debug session in IAR EW430 or Code Composer studio, the
target MSP430 device enters the low-power modes. Wake-up times can be measured on F5xx, F6xx,
FR5xx, and FR6xx devices. For some MSP430 devices, special debug features are disabled in this mode;
for example, setting breakpoints (hardware and software) while device is running in ULP mode.
NOTE:
When debugging with Ener+ active, this mode must be used.
NOTE:
Measured currents might be slightly higher than in stand-alone mode (EnergyTrace) due to
the active debugger connection.
For more details and information, see the
MSP430 Ultra-Low-Power LPMx.5 Mode
section of
the
IAR Embedded Workbench Version v7+ for MSP430 User's Guide
and

EnergyTrace™ Technology
EnergyTrace technology is an energy-based code analysis tool that measures and displays the energy
profile of an application, which helps to optimize it for ultra-low power consumption.
MSP devices with built-in
Ener[CPU State]+[Peripheral States]
(or in short
Ener+
)
technology allow real-time monitoring of many internal device states while user program code executes.
Ener+ technology is supported on selected MSP devices and debuggers (see
).
EnergyTrace
mode (without the "++") is a fundamental part of
EnergyTrace technology
and enables
analog energy measurement to determine the energy consumption of an application but does not correlate
it to internal device information. The EnergyTrace mode is available for all MSP devices with selected
debuggers, including CCS (see
).
