Comes with Real Time Transfer (RTT) for interactive user I/O in embedded applications and High Speed Sampling (HSS) for data acquisition

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

J-Link EDU Mini is the educational model for non-commercial use only. J-Link BASE Compact is a 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 the most widely used debug probes on the market. J-Link opens the door 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 maximises 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. “We are excited to announce compatibility of SEGGER debugging solutions with Arduino Portenta.”

The tutorial “Using the SEGGER J-Link Debugger with the Portenta Breakout” helps 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 analyser.

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

Developers can now purchase the SEGGER J-Link devices and adaptors: J-Link EDU Mini, J-Link BASE Compact, J-Link PLUS Compact and J-Link PRO from the Arduino store.
