J-Link Setup

The J-Link is a debug probe from Segger. It is available as a stand-alone product, but also integrated into evaluation boards directly.

Due to the proprietary nature of the J-Link, probe-rs will not achieve the same speed as the official J-Link tools.



No additional drivers are required to use a J-Link debug probe on Linux systems. To ensure that users without root privileges can use the debug probe, it is recommended to configure udev as described in udev rules.


Unfortunately, probe-rs doesn't work with the official drivers on Windows. To use probe-rs it is necessary to install a generic WinUSB driver. The recommended way of doing this is by using Zadig and selecting WinUSB as the driver for the J-Link probe. This will uninstall the official driver, which means that the official Segger tools will not work anymore after this.

Mac OS
