J-Link EDU – The Educational J-Link

Low-cost J-Link for educational purpose J-LINK EDU is identical to J-Link BASE and offers the same functionality. It has been designed to allow students and educational facilities as well as hobbyists access to top of the line debug probe technology.

Supports a broad range of microcontrollers
Multiple CPUs supported—8051, PIC32, RX, ARM7/9/11, Cortex-M/R/A, RISC-V
Download speed up to 1 MB/s
Supports unlimited breakpoints in flash memory, additional license required.
Built-in VCOM functionality

Full J-Link Support

The J-Link EDU license includes the unlimited breakpoints in flash memory feature. With the Flash Breakpoints, developers may set an unlimited number of breakpoints in flash memory helping to debug applications that run from flash memory.

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)

Limitations - Licensing and Support

J-Link EDU may only be used for non-commercial purposes.
J-Link EDU does not come with support. In case of questions / problems, you can visit our community forum. However, there is no claim for guaranteed support in the forum. View forum rules for more information.
