Debug from home: SEGGER’s J-Link Remote Server adds encryption

Published: 25 March 2020 - Rachael Morling

Working from home has become a necessity for many of us. Given the ongoing changes in the working environment, it is very likely that some amount of work-from-home time will become not just more common but will be “the new normal”.

SEGGER’s J-Link Remote Server is a proven way to debug remotely. It has been used for years to debug target systems, thousands of miles away, even behind firewalls. Of its many uses in the past, a particularly important one was for system bring-up when hardware availability was limited, expensive, or otherwise difficult. Today an even more important application has moved into focus.

It is not only impractical for developers to carry hardware home, with J-Link Remote Server it is also unnecessary. Developers can simply connect from home and use any tool that supports J-Link. The J-Link operates exactly the same as if it were sitting right on the developer’s desk. J-Link Remote Server was first convenient, then very useful, and is now on its way to becoming indispensable.

Paired with authenticated access to the J-Link Remote Server, and the encrypted communication tunnel between software and probe, remote access is another rock-solid debug option for the J-Link based on the proven algorithms of emCrypt. The authentication uses challenge-response methods to ensure the password is never visible on the wire. The end-to-end encryption of the debug stream ensures that the application can be securely transferred via wire.

The J-Link Remote Server can be used at no cost with any J-Link model, including base models with only USB interface. The software is included in the “J-Link Software and Documentation Package” that comes with every model J-Link or J Trace.
