ULINKpro Debug and Trace Unit

ULINKpro Debug and Trace Unit Image (View Larger ULINKpro Debug and Trace Unit Image)
The Keil 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-ARM, provides extended on-the-fly debug capabilities for Cortex-M devices. You are able to control the processor, set breakpoints, and read/write memory contents, all while the processor is running at full speed. High-Speed data and instruction trace are streamed directly to your PC enabling you to analyze detailed program behaviour.
