WSL

Windows Subsystem for Linux (WSL) is a part of Windows 10, that allows the user to run Linux applications on Windows.

J-Link specifics

As of now WSL does not fully support USB devices.

In order to connect to a J-Link from WSL you either have to use the Ethernet / WiFi interface (if present, see Model overview) or make use of the J-Link Remote Server that runs on an another machine, capable of USB.

For more details please refer to the following article: Connecting to J-Link using J-Link Remote Server

Example setup with USB

J-Link Commander

In this example we will connect to our J-Link (connected via USB to the host) from WSL using the J-Link Remote Server on the host side and the J-Link Commander on the WSL side.

Requirements

• Windows 10 system which has the J-Link Software and Documentation Pack installed
• WSL system which has the J-Link Software and Documentation Pack installed
• J-Link connected via USB to the host Windows 10 system

Steps

1. Start the J-Link Remote Server in LAN mode on the Windows 10 host system and select the correct J-Link if prompted.
   
   

   J-Link Remote Server: Startup screen
   
   
2. The J-Link Remote Server will now wait for incoming connections:
   
   

   J-Link Remote Server: Started and waiting for connections
   
   
3. Switch to the command-line prompt of your WSL Linux system.
4. Insert your target device and interface into the following command and execute it: JLinkExe -device <your-device> -ip localhost -if <target-interface> -speed 4000 -autoconnect 1
   • In this example we will connect to the NXP Kinetis K66 device on our emPower board, so the command would be as follows: JLinkExe -device MK66FN2M0XXX18 -ip localhost -if SWD -speed 4000 -autoconnect 1
5. Now you should be able to make use of the commands of the J-Link Commander.
