SEGGER announces a beta release of their new J-Link Debugger

SEGGER invites the J-Link/J-Trace community to join in testing a free Beta release of the new J-Link Debugger software, a full-featured graphical debugger for embedded applications.

With J-Link Debugger it is possible to debug any embedded application on the C source and assembly language level. It can load applications built with any toolchain/IDE or debug the target's resident application without any source.

J-Link Debugger increases development speed by extending the rich feature set and robust high performance of the J-Link/J-Trace family of debug probes. Scriptable project files automate setup making it easy to get started.

Ultra-fast flash downloads, an unlimited number of breakpoints even when debugging in flash memory and the SEGGER Real-Time-Terminal are all features which may be utilized from within the SEGGER J-Link Debugger. The SEGGER Real-Time-Terminal feature alone will drastically change the way in which debugging is done.

Used with one of the high-end trace models (J-Trace Cortex-M) the J-Link Debugger supports instruction trace.

“SEGGER J-Link Debugger is the latest addition to the extensive family of J-Link software tools which include J-Flash, J-Link Commander, J-Link GDB Server, J-Link RDI/RDDI, J-Scope, J-Link SWO Viewer, and J-Mem,” says Alexander Gruener, Product Manager of the SEGGER J-Link family of debug probes.

About J-Trace

J-Trace is the most feature rich offering of the J-Link family adding instruction trace capabilities using ARM’s Embedded Trace Macrocell (ETM). The J-Trace models have an internal trace memory. Their direct interface to the ETM allows maximum trace frequency. ETM instruction trace allows the developer to look at the history of a program’s execution. This is useful, for example, when a program crash is caused by an unexpected jump. In this case the developer can track back to where the program execution left its intended flow.

About J-Link

The SEGGER J-Link is the most popular debug probe on the market. It is tool chain independent and works with free GDB-based tool chains such as emIDE and Eclipse, as well as commercial IDEs from: Microchip (MPLAB® X), Atmel, Atollic, Coocox, Cosmic, Freescale, IAR, KEIL, Mentor Graphics, Python, Rowley, Renesas, Tasking and others. With the J-Link family, investments in the debug probe are preserved when changing compiler or even CPU architecture. J-Link supports multiple CPU families, such as ARM 7, 9, 11, Cortex-M0, M0+, M1, M3, M4, R4, A5, A8, A9 as well as Renesas RX100, RX200, RX610, 620, 62N, 62T, 630, 631, 63N and Microchip PIC32; there is no need to buy a new J-Link or new license when switching to a different yet supported CPU family or tool-chain. SEGGER is also continuously adding support for additional cores, which in most cases, only requires a software/firmware update. Unlimited free updates are included with even the baseline model of the J-Link family. SEGGER is excited to continue advanced development of its cutting edge embedded tool solutions to be utilized with pretty much any development environment you choose. All J-Links are fully compatible to each other, so an upgrade from a lower-end model to a higher-end model is a matter of a simple plug-and-play.
