SEGGER’s J-Link now compatible with Arduino

SEGGER and Arduino have announced that SEGGER’s J-Link debugging solutions are now fully compatible with Arduino Portenta boards and IDE.

Developers will be able to purchase a J-Link from the Arduino store. At the moment, Arduino can offer four of the SEGGER J-Link models: J-Link EDU Mini, J-Link BASE Compact, J-Link PLUS Compact and J-Link PRO.

J-Link EDU Mini is the educational model for non-commercial use only. J-Link BASE Compact is the much faster model for commercial applications. J-Link PLUS Compact includes an unlimited number of flash breakpoints plus the Ozone J-Link debugger, SEGGER’s full-featured graphical debugger for embedded systems. The J-Link PRO is full-featured and even faster. In addition to USB it also has an Ethernet connection.

SEGGER J-Links are widely used debug probes and are able to provide access to all major development tools, from commercial toolchains to GDB-driven ones. With unique features such as Real Time Transfer (RTT) for interactive user I/O in embedded applications, and High Speed Sampling (HSS) for data acquisition, J-Link has been designed to maximise the visibility of the target system in a non-intrusive way.

“By offering our J-Link debug probes, Arduino is raising the level of professional development tools and methods available to its community,” said SEGGER CEO Ivo Geilenbruegge. “J-Link makes application development on Portenta boards faster, easier and more efficient.”

“Our partnership with SEGGER marks a step forward to further support developers in creating their own embedded systems,” commented Stefano Implicito, Product Marketing Manager at Arduino.

The tutorial “Using the SEGGER J-Link Debugger with the Portenta Breakout” has been created to help the user get started quickly. It shows how to debug an Arduino sketch by connecting the Portenta Breakout to the SEGGER J-Link device and using the Ozone debugger and performance analyzer.

To connect the Portenta boards with J-Link debug probes, two adapters are available. SEGGER’s 50-Mil 10-Pin Patch Adapter and the 19-pin Cortex-M Adapter. The 50-Mil 10-Pin Patch Adapter allows custom connections/wiring between the 20-pin and 10-pin side. The 19-Pin Cortex-M Adapter allows JTAG, SWD, and SWO connections between J-Link and Cortex-M-based target hardware systems.
