THE I-JET TRACE CM AND I-JET TRACE A/R/M IN-CIRCUIT

DEBUGGING PROBES

I-jet Trace CM and I-jet Trace A/R/M are in-circuit debugging probes, designed to take

full advantage of the speed and current delivery of the USB3 communication ports.

USB 2.0 is also supported, but not recommended due to slower speed and smaller power

delivery.

I-jet Trace CM and I-jet Trace A/R/M have all the features of I-jet, but with enhanced

performance and ETM (Embedded Trace Macrocell) support, which allows for

real-time tracing of the instruction and data over a 1, 2 or 4-bit trace bus on Cortex-M

devices.

I-jet Trace A/R/M provides extensive debug and trace functionality for Arm Cortex

devices equipped with the CoreSight

debug interface. I-jet Trace A/R/M is equipped

with up to 16-bit wide trace data collection.

Note: Whenever I-jet Trace is mentioned in this document, both the I-jet Trace CM and

the I-Jet Trace A/R/M probes are referred to, unless otherwise explicitly specified.
