J-Trace PRO for Cortex-M

JTAG debug probe with trace support for Cortex-M cores J-Trace for Cortex-M

J-Trace PRO for Cortex-M is setting a new standard for trace probes. It enables continuous streaming trace via its Gigabit Ethernet interface, lifting the limitations by internal buffers and slow data transmission.

J-Trace PRO can capture complete traces over long periods - thereby enabling the recording of infrequent, hard-to-reproduce bugs. This is particularly helpful when the program flow 'runs off the rails' and stops in a fault state. 

It also supports extended trace features, such as code coverage (so engineers have visibility of which parts of the application code have been executed) and execution profiling (providing visibility as to which instructions have been executed and how often - so hotspots can be addressed and optimisation opportunities identified).


  • Supports Streaming Trace (trace data is streamed to PC/debugger in real time, unlimited trace buffer)
  • Has all the J-Link functionality
  • Gigabit Ethernet interface
  • Hi-Speed-USB 2.0 interface (480 MBit/s)
  • JTAG speed: 50 MHz
  • Works with all currently available Cortex-M devices up to 150 MHz ETM trace clock (300 MHz CPU clock)
  • Supports Cortex-M0/M0+/M1/M3/M4/M7 targets
  • Supports ARM's Embedded Trace Macrocell (ETM)
  • Supports ARM's Embedded Trace Buffer (ETB)
  • Supports ARM's Micro Trace Buffer (MTB)
  • Free software updates, two years of support
  • 64 MB on-board trace buffer for legacy one-shot tracing mode
  • pdf Documentation download
