Use of software

SEGGER J-Link software may only be used with original SEGGER products and authorized OEM products. The use of the licensed software to operate SEGGER product clones is prohibited and illegal.

Use of the software with 3rd party tools

For simplicity, some components of the J-Link software are also distributed by partners with software tools designed to use J-Link. These tools are primarily debugging tools, but also memory viewers, flash programming utilities as well as software for other purposes. Distribution of the software components is legal for our partners, but the same rules as described above apply to their usage: They may only be used with original SEGGER products and authorized OEM products. The use of the licensed software to operate SEGGER product clones is prohibited and illegal.

Original SEGGER products

The following products are original SEGGER products for which the use of the J-Link software is allowed:


J-Link PRO

J-Link PRO is a refined version of the regular J-Link. It has an Ethernet interface in addition to the USB interface, as well as two additional LEDs which are used as hardware status indicators.
It connects via Ethernet or USB to the Windows (2000 and later) PC host.

J-Link Pro is fully compatible with J-Link and can be used "out-of-the-box". J-Link Pro uses DHCP per default.

The built-in webserver makes manual configuration easy and convenient. Ethernet allows using the emulator far away from the PC in a development or production environment; download and debugging speed is higher and Ethernet provides electrical isolation from the PC.

All features of the regular J-Link also apply to this product.

J-Link OEM versions

There are several different OEM versions of J-Link on the market. The OEM versions look different, but use basically identical hardware. Some of these OEM versions are limited in speed, some of these can only be used with certain chips and some of these have certain add-on features enabled, which normally require a license. In any case, it should be possible to use the J-Link software with these OEM versions. However, proper function cannot be guaranteed for OEM versions. SEGGER Microcontroller does not support OEM versions; support is provided by the respective OEM.
