Introduction
This document describes the features and hardware details of the XMC™ Link. XMC™ Link is an isolated debug
probe for all XMC™ microcontrollers.
The debug probe is based on SEGGER J-Link debug firmware, which enables use with DAVE™ and all major
third-party compiler/IDEs known from the wide ARM® ecosystem. Table 1 shows its specification.

Getting started
To operate the XMC™ Link the installation of the J-Link Driver is required.
1. Please download the latest version from
https://www.segger.com/jlink-software.html
and install it on your
PC/laptop.
Note: The J-Link driver is also part of the typical installation of DAVE™ and 3rd party tools supporting SEGGER J-
Link.
2. Connect XMC™ Link with your PC/laptop using the Micro USB cable.
3. A proper connection and installation of the J-Link driver is indicated by a constantly illuminated DEBUG
LED.
4. Connect your XMC™ target board with XMC™ Link using one of the enclosed cables.
5. Select SEGGER J-Link as debugger in your preferred IDE e.g. DAVE™
6. Start the flash programming and debugging session

Hardware description
The following chapters provide a detailed description of the hardware and how it can be used. The hardware is
depicted in Figure 2.

Known limitation
XMC Link™ V1 has a minor known limitation which could occur only during programming the BMI of a XMC1000
device in ASC-BSL mode to another BMI mode. This limitation is solved in the PCB version V1.1. The version
number is printed on the bottom side of the PCB below the USB connector.
The limitation can be avoided if the XMC™ Link V1 is powered before the target XMC™ will be powered.

Debug connector
The XMC™ Link can be connected to the XMC™ target microcontroller by either of the debug connectors:
