Introduction
This chapter gives a short overview of the I-jet in-circuit debugging probe.
More specifically, this means:
●The I-jet In-Circuit Debugging Probe
●Requirements
●Supported ARM core families
●Supported operating systems
●Connections.
The I-jet In-Circuit Debugging Probe
I-jet is an in-circuit debugging probe, which connects to the target board via a JTAG or
SWD connection, and to the host PC via the USB port. I-jet is also referred to as a debug
probe, debug adapter, or JTAG in-circuit emulator by different tool vendors.

User Guide
Besides the typical JTAG debugging, I-jet is capable of providing power to the target
board and measuring it with sufficient accuracy to provide a power profile during
program execution in real time. This feature is referred to as power debugging.
Figure 2: Communication overview
For debugging Cortex-M devices, I-jet supports the SWO (Serial Wire Output) feature,
which can be used for tracing the program execution and sending variables at predefined
points in your code. I-jet streams the program counter, variables, and power
measurement data to the host PC to provide a much better view into program execution
in real time.
Requirements
I-jet needs to be controlled by the IAR C-SPY® Debugger which comes with the IAR
Embedded Workbench® IDE.

Working with I-jet
This chapter describes how to work with I-jet. More specifically, this means:
●Setup and installation
●Connecting the target system.
For information about debugging using I-jet, see the C-SPY® Debugging Guide
for ARM.
Setup and installation
SOFTWARE
I-jet requires IAR Embedded Workbench for ARM to be installed.
PROBE SETUP
I-jet does not require any special driver software installation. All drivers for I-jet are part
of the installation of IAR Embedded Workbench for ARM.
If you need to install the driver manually, navigate to
\Program Files\IAR Systems\Embedded Workbench x.x\arm\drivers\jet
\USB\32-bit or 64-bit (depending on your system). Start the dpinst.exe
application. This will install the driver.
For information about using multiple I-jet probes on the same PC, see the C-SPY®
Debugging Guide for ARM.
Connecting the target system
POWER-ON SEQUENCE
When the target power is not provided by I-jet, you do not need to follow any special
powering sequence. Connect I-jet to a powered and running target board and start
debugging.
When hot-plugging, the target GND and the USB host GND must be at the same level.
To prevent damage due to GND differences, make sure that the PC and the target board
power supply are connected to the same wall outlet or a common desktop power strip.

User Guide
POWER UP YOUR EVALUATION BOARD
If you have an evaluation board that is prepared for it, you can power the board via I-jet
through pin 19 on the 20-pin 0.1 in pitch JTAG connector, or pin 11/13 on the small 0.05
in pitch MIPI-20 connector. Target power of up to 400 mA can be supplied from I-jet
with overload protection. Most of the IAR Systems KickStart Kits contain an evaluation
board that can be powered this way.
Note: The target board will get power via I-Jet once you start the compile and
download routine, but not before.
