We often get asked what the benefits are upgrading from a older J-Trace CM (SN starting with 23) to a J-Trace PRO Cortex (SN starting with 75 or 93). The following list shows the improvements over the older J-Trace model:

  • Supports streaming trace, enabling live trace features like live code coverage, code profiling and execution counters.
  • Faster maximum Traceclock supported (150 MHz) for even the fastest target devices.
  • GBit Ethernet Interface for easier remote access to J-Trace + higher transfer speed than USB2.0.
  • USB3.0 interface for very fast transfer speeds to host PC for trace analysis.
  • Adjustable trace clock sampling timing for easier troubleshooting of trace connections with target devices that are out of Arm trace specification.
  • Tracing on Cortex-A, -R additionally to Cortex-M supported on the J-Trace PRO Cortex.
  • Making use of all debug features offered by Ozone.
  • Faster maximum SWO clock speed, 100 MHz instead of 6 MHz.
