Free Software Updates
As a legitimate owner of a SEGGER J-Link, you can always download the latest software free of charge. Though not planned and not likely, we reserve the right to change this policy. Note that older models may not be supported by newer versions of the software. Typically, we support older models with new software at least 3 years after end of life.
Supports concurrent access to CPU by multiple applications
J-Link allows multiple applications to access a CPU at the same time. This has numerous applications. J-Link commander can be used in parallel to a debugger, a tool to communicate via DCC can be used in parallel to a debugger or a visualization tool such as the debugger Ozone, the RTTViewer, SystemView or the kernel viewer embOSView.
