U-link2 JTAG Debugger

Keil U-Link

The Keil ULINK2 of USB-JTAG Adapter connects your PC's USB port to your ARM processor-based target hardware (via JTAG,SWD or OCDS) allowing you to program and debug embedded programs on the target hardware

 

ULINK2 Features:

  • Plug-and-Play installation using standard Windows USB drivers, 

  • Serial Wire Debug (SWD) support for ARM Cortex-M3 based devices,  Real-Time Trace for Cortex-M3 using Serial Wire Viewer (SWV)

 

  • Real-Time Agent with memory R/W during execution, terminal emulation, and serial debug output.

  • 10-pin connector support (20-pin connector continues to be supported).

 

ULINK2 may be used for:

  • On-chip Debugging (using on-chip JTAG, SWD, or SWV),

  • Flash Memory Programming (using user-configurable Flash programming algorithms).

Using the Keil µVision IDE/Debugger with the ULINK2 adapter, you can easily create, download, and test embedded applications on actual target hardware.
