Which ULINK?

ULINK2 is an entry-level debugger for Cortex-M devices. Control the processor, set breakpoints, and read/write memory contents, all while the processor is running at full speed.

ULINKplus combines isolated debug connection, power measurement, and I/O for test automation. Function, timing, and power consumption visibility enables developers to optimize applications further.

This sophisticated unit enables developers to program, debug and analyze applications using high-speed streaming trace, which is required for code coverage and performance analysis.
