J-Trace Overview

SEGGER’s J-Trace is a professional streaming trace probe that offers the best possible trace experience, boasting an extensive list of features that fulfill any embedded developers’ debugging needs. With unlimited streaming trace, Live Code Profiling and Live Code Coverage, developers can isolate and identify hard-to-find code defects.

The J-Trace offers multi-platform support for Windows, macOS and Linux making it very versatile. This is also reflected in its support for most popular IDEs. The free, stand-alone debug software Ozone can be used for any toolchain to enable tracing. For quick and easy first steps, there are trace reference boards available.

The J-Trace series comprises different models. Equipped with full J-Link debug functionality, the J-Trace PRO is designed to support the advanced tracing features of all popular cores and architectures. Specialized models provide support for Cortex-M-based microcontrollers (J-Trace PRO Cortex-M), Cortex-A/R/M-based microcontrollers (J-Trace PRO Cortex-A/R/M), and RISC-V-based microcontrollers (J-Trace PRO RISC-V). All of them deliver large trace memory capacities and high-speed communication via USB SuperSpeed 3.0.
