16 CHAPTER 2 Licensing

2.1

Introduction

J-Link functionality can be enhanced by the features RDI, flash download and flash breakpoints. These features do not come with J-Link and need additional licenses. In this chapter the licensing options of the software will be explained.

2.2

Software components requiring a license

There are three software components which need an additional license:

• J-Link RDI

• Flash download

• Flash breakpoints

The RDI license is essential for using the RDI feature. A license for flash download and flash breakpoints is optional, but both of them require a RDI license in order to use them.

2.3

License types

For each of the software components which require an additional license (RDI, flash download, flash breakpoints), there are three types of licenses:

Built-in License

This type of license is easiest to use. The customer does not need to deal with a license key. The software automatically finds out that the connected J-Link contains the built-in license(s). This is the type of license you get if you order J-Link and the license at the same time, typically in a bundle.

Key-based license

This type of license is used if you already have a J-Link, but want to enhance its functionality by using RDI, flash download and flash breakpoints. In addition to that, the key-based license is used for trial licenses. To enable this type of license you need to obtain a license key from SEGGER. Free trial licenses are available upon request from

www.segger.com

This license key has to be added to the RDI license management.

How to enter a license key is described in detail in the section Key-based license on page 17. Every license can be used on different PCs, but only with the J-Link the

license is for. This means that if you want to use J-Link RDI, flash download and/or flash breakpoints with other J-Links, every J-Link needs a license.

Device-based license

The device-based license comes with the J-Link software and is currently available for NXP LPC devices from LPC21xx to LPC24xx. It includes a license for RDI, flash download and flash breakpoints. The device-based license has to be enabled by the customer via the J-Link RDI configuration dialog. How to enable a device-based

license is described in detail in the section Device-based license on page 17.

2.3.1

Built-in license

This type of license is easiest to use. The customer does not need to deal with a license key. The software automatically finds out that the connected J-Link contains the built-in license(s). To check what licenses the used J-Link have, simply open the

J-Link commander (JLink.exe). The J-Link commander finds and lists all of the J-

Link’s licenses automatically, as can be seen in the screenshot below.

This J-Link for example, has built-in licenses for RDI, flash download (FlashDL) and flash breakpoints (FlashBP).

2.3.2

Key-based license

When using a key-based license, a license key is required in order to enable the J-

Link features RDI, flash download and flash breakpoints. License keys can be added via the RDI license management. The RDI license management can be found in the

RDI configuration dialog. For more information about how to use the RDI license

management, please refer to chapter License (J-Link RDI License managment) on page 43. Like the built-in license, the key-based license is only valid for one J-Link,

so if another J-Link is used it needs a separate license.

When using RDI and no license is found by the software, it will ask for a key. The error dialog should look like in the screenshot below.

If Enter license is chosen, the RDI license management dialog opens and the license

key can be added as described in chapter License (J-Link RDI License managment) on page 43.

If one of the features flash download and flash breakpoints is used and no license is found, an appropriate error dialog appears.

2.3.3

Device-based license

The device-based license is a free license, available for NXP LPC devices from

LPC21xx to LPC24xx. It’s already included in the J-Link RDI software, so no keys are necessary to enable this license type. To activate a device based license, a supported device needs to be selected. The device-based license includes a valid license for

RDI, flash download and flash breakpoints.

2.3.3.1

Enabling a device-based license

In order to enable a device-based license, flash programming has to be enabled and the appropriate device has to be selected. For example if the device-based license for

RDI and flash download for a NXP LPC2378 shall be enabled, the J-Link RDI configuration dialog should look like in the screenshot below.

For more information about the J-Link RDI configuration dialog, please refer to chap-

ter Configuration dialog on page 43.
