ULINK Debug and Trace Adapters

Learning Platform

A ULINK debug adapter connects your PC's USB port to your target system (via JTAG or a similar debug interface) and allows you to debug, trace and analyze embedded programs running on the target hardware. All ULINK adapters enable you to:

  • 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
  • Connect to a target via JTAG or serial wire modes
  • Debug ARM Cortex-M devices on-the-fly
  • Examine trace information from ARM Cortex-M3/M4/M7 devices
