*These software components require a separate license (each component). To make it as simple as possible, there are J-Link models available which already come with built-in licenses for these components. For more information, please refer to www.segger.com/jlink-debug-probes.html. For users who already own a J-Link without built-in licenses for these software components, a license key may be purchased separately: www.segger.com/pricelist-j-link-related.html

J-Link Configurator

The J-Link Configurator makes it easy to manage all the J-Links in your development and product environments. A screenshot of J-Link Configurator shows the main application while several J-Links are connected via USB and Ethernet.

J-Link GDB Server

J-Link GDB Server is an application acting as a server for debuggers or IDEs communicating with the J-Link debug probe via TCP/IP using the GDB protocol. It allows using J-Link with GDB and the growing number of debuggers and IDEs that use the same protocol.

J-Link Remote Server

The J-Link Remote Server is a small server application that allows using J-Link remotely via TCP/IP.

J-Link Commander

J-Link Commander (JLink.exe) is a command line based utility that can be used for verifying proper functionality of J-Link as well as for simple analysis of the target system. It supports some simple commands, such as memory dump, halt, step, go etc. to verify the target connection.

J-Mem

J-Mem displays memory contents of ARM-systems and allows modifications of RAM and sfrs (Special function registers) while target is running.

J-Link SWO Viewer

J-Link SWO Viewer is a tool which allows showing terminal output of the target performed via the SWO pin.

J-Flash

J-Flash is a PC software running on Windows systems, which enables you to program the internal and external flash of your microcontroller via J-Link.

J-Link Unlimited Flash Breakpoints

The J-Link software comes with an additional feature, called Unlimited Flash Breakpoints. Unlimited Flash Breakpoints allow the user to set an unlimited number of breakpoints when debugging in flash memory.
