ULINK Family of Debug Adapters

The Keil ULINK family of Debug Adapters connect your PC's USB port to your target system (via JTAG or similar debug interface) and allow you to debug embedded programs running on target hardware.

The 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 using JTAG or Serial Wire modes
• On-the-fly debug of ARM Cortex-M based devices
• Examine Trace information from ARM Cortex-M3 and Cortex-M4 devices
