J-Link DLL Updater

The J-Link DLL Updater is a tool provided by SEGGER to update the J-Link DLL used by applications that support J-Link, such as IDEs. Software that uses the J-Link DLL to include J-Link support usually comes with its own version of the J-Link DLL. While this provides a good out-of-the-box experience, it also means that support for new devices will not be automatically available in such applications. To update the J-Link DLL, you need to close all J-Link related applications, download the latest version of the J-Link software, and run the installer. At the end of the installation process, the J-Link DLL Updater will pop up and you can use it to update the J-Link DLL used by your application1. If the updater cannot find the DLL of your IDE installation, you may need to update it manually by locating JLink_x64.dll and/or JLinkARM.dll within the install directory of your IDE and replacing them with the ones that were just installed1.
