In this article, we will delve into the features and benefits of the J-Link ARM suite, exploring its capabilities and how it can enhance your debugging experience.

What is J-Link ARM?

The J-Link ARM suite is a software package that complements the J-Link product line, providing a range of advanced features and capabilities. By installing the J-Link ARM suite, users can unlock the full potential of their J-Link products, enabling them to debug and develop their applications with greater ease and precision. The suite consists of two DLLs (Dynamic Link Libraries) that need to be copied to the same folder and selected in the debugger to function properly.

Key Features of J-Link ARM

The J-Link ARM suite offers a range of key features that make it an indispensable tool for developers. Some of the most notable features include:

Unlimited Flash Breakpoints: Unlike traditional ICE (In-Circuit Emulator) debuggers, which are limited to two hardware breakpoints, the J-Link ARM suite allows users to set an unlimited number of flash breakpoints. This enables developers to debug their applications with greater precision and accuracy.
RDI Compliant Debugger Support: The J-Link ARM suite is designed to work seamlessly with any RDI (Real-Time Debug Interface) compliant debugger. This ensures that users can integrate the J-Link ARM suite with their existing debugging tools and workflows.
Stabilization and Control of Debug Scenarios: The two DLLs included in the J-Link ARM suite are designed to stabilize and control debug scenarios, providing a more stable and reliable debugging experience.
