The Keil ULINK family of debug and trace adapters connects the host computer via USB to your target system. ULINK uses on-chip debug interfaces and supports application debugging and flash programing.
The ULINK family supports traditional features like simple and complex breakpoints, watch windows, and execution control. Using the Serial Wire Output (SWO), additional trace features like system analyzer are supported.
ULINKpro interfaces to ETM trace connectors and uses streaming trace technology to capture the complete instruction trace for code coverage and execution profiling.
ULINKplus additionally offers power measurement for energy optimization and I/Os for test automation.
