Setting up the IP interface

Some emulators of the J-Link family have (or future members will have) an additional
Ethernet interface, to communicate with the host system. These emulators will also
come with a built-in web server which allows configuration of the emulator via web
interface. In addition to that, you can set a default gateway for the emulator which
allows using it even in large intranets. For simplicity the setup process of J-Link Pro
(referred to as J-Link) is described in this section.
3.4.1

Connecting the first time

When connecting J-Link the first time, it attempts to acquire an IP address via DHCP.
To get information about which IP address is acquired, you have to possibilities:
• Connecting J-Link via USB and via Ethernet and read out the IP address via
JLink.exe.
• Connecting J-Link only via Ethernet and read out the IP via the DHCP IP Assign-
ment table of your DHCP Server.
In the following, both ways to get the IP address assigned to J-Link via DHCP, are
explained.
3.4.1.1 Connecting via USB and Ethernet
When using JLink.exe in order to read out the IP address, J-Link has to be con-
nected to your host system via Ethernet and via USB. When starting JLink.exe, it
will show information about the IP address (static / dynamic) when connecting to J-
Link.
To get more detailed information about the current configuration of the J-Link (such
as subnet mask and MAC address), you can use the conf command in JLink.exe.
After reading out the IP address you can connect to J-Link via Ethernet, using the IP
address.
