Unlimited Breakpoints
The unlimited breakpoints in flash memory feature can be used free of charge for evaluation. The evaluation period is not time limited. For commercial use a separate license is required.
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 Micrium's u/C-Probe or SEGGER's kernel viewer embOSView. This feature is currently not available for Cortex A and R cores.
Crossplatform support
runs on Windows, Linux, macOS. The MAC and Linux versions are fully usable, but limited to the following components:
J-Link Commander, command line GDBServer, shared library (DLL-equivalent)
