SETUP AND INSTALLATION
Software
Before you can use I-jet Trace, you need to install IAR Embedded Workbench for Arm.
For information, see the Installation and Licensing Quick Reference Guide and the
Licensing Guide.
Probe setup
I-jet Trace does not require any special driver software installation. Normally, all drivers
for I-jet Trace are automatically installed as part of the IAR Embedded Workbench
installation.
If you need to install the USB driver manually, navigate to
\Program Files\IAR Systems\Embedded Workbench x.x\arm\drivers\jet
\USB3\32-bit
or 64-bit (depending on your system). Start the dpinst.exe
application. This will install the USB driver.
The USB LED will flash twice after enumerating on the USB2 ports, and three times on
USB3 ports.
For information about using multiple I-jet probes on the same host computer, see the
C-SPY® Debugging Guide for Arm.
CONNECTING THE TARGET SYSTEM
Power-up your I-jet Trace probe
1
Connect I-jet Trace to the host computer using the USB3 micro cable or any other
compatible high-quality USB3 cable.
2 Connect I-jet Trace to the target board using the cable that matches the target board
connector (MIPI-20, MIPI-10, or Mictor-38). If a standard JTAG connector is used,
you must first plug the ADA-MIPI20-ARM20 adapter into the JTAG connector.
Note: No harm is done if the above order is reversed.
To prevent damage, the target GND and the USB host GND must be at the same level.
When hot-plugging, make sure that the PC and the target board power supply are
connected to the same grounded wall outlet or a common grounded desktop power strip.
Supplying target power from I-jet Trace
I-jet Trace can only supply power to the target board through the MIPI-20 and Arm-20
connections. The Mictor interface does not facilitate powering targets from the debug
probes.
