Converting ST-LINK on-board into a J-Link

SEGGER offers a firmware upgrading the ST-LINK on-board on the Nucleo and Discovery Boards. This firmware makes the ST-LINK on-board compatible to J-Link OB, allowing users to take advantage of most J-Link features like the ultra fast flash download and debugging speed or the free-to-use GDBServer.

Recommended Software

SEGGER Embedded Studio

SEGGER Embedded Studio is a streamlined and powerful C/C++ IDE (Integrated Development Environment) for ARM microcontrollers. It is specifically designed to provide users with everything needed for professional embedded development: an all-in-one solution providing stability and a continuous workflow.


SEGGER SystemView

SEGGER SystemView is a real-time recording and visualization tool that reveals the true runtime behavior of an application, going far deeper than the insight provided by debuggers. This is particularly effective when developing and working with complex systems comprising multiple threads and interrupts: SystemView can ensure a system performs as designed, can track down inefficiencies, and show unintended interactions and resource conflicts.
