ULINKpro Debug and Trace Unit

Learning Platform

The ULINKpro debug and trace unit connects your PC's USB port to your target system (via a JTAG, Cortex Debug, or Cortex Debug + ETM connector). It allows you to program, debug, and analyze your applications using its unique streaming trace technology.

ULINKpro, together with MDK, provides extended on-the-fly debug capabilities for Cortex-M devices. High-Speed data and instruction trace are streamed directly to your PC enabling you to analyze detailed program behavior.

Broad Device Support

ULINKpro connects to a wide variety of processor targets, including ARM7, ARM9, and all Cortex-M processor based devices.

Run/Stop Debugging

Using ULINKpro, you can

  • download programs to your target hardware
  • examine memory and registers
  • single-step through programs and insert multiple breakpoints
  • run programs in real-time
  • program Flash memory

High-Speed Connections

ULINKpro offers fast and reliable target connections:

  • Data and event trace for Cortex-M up to 100 Mbit/s (Manchester mode)
  • Instruction trace for Cortex-M3, Cortex-M4, and Cortex-M7 up to 800 Mbit/s (not supported with ULINKpro D)
  • JTAG clock speed up to 50 MHz
  • ETM trace: supports Cortex-M devices running at up to 200 MHz (selected devices may have trace-port bandwidth limitations).
  • High-speed memory read/write up to 1 MBytes/s

Streaming Trace

The unique streaming trace capabilities of ULINKpro deliver sophisticated analysis features such as:

  • Complete code coverage information about your program's execution ensures thorough application testing and verification
  • Performance analysis using the Execution Profiler and Performance Analyzer enable you to identify program bottlenecks, optimize your application, and to isolate problems.
  • Streaming instruction trace requires the target device to have ETM (Embedded Trace Macrocell)


    Note Note

    The ULINKpro D has the same high debug performance as ULINKpro, but does not support instruction trace.
