Instruction Tracing with SEGGER J-Link/J-Trace and Atollic TrueStudio
ETM instruction trace allows the developer to look at the history of program 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 the intended flow of the program.
“By adding instruction trace, Atollic’s TrueStudio becomes one of the top players in the tool-chain market for embedded systems”, says Dirk Akemann, Marketing Manager of SEGGER.
“SEGGER is the leading provider of debug probes and the combination of Atollic TrueSTUDIO and J-Trace provides engineers market-leading debugging and programming tools”, says Magnus Unemyr, Atollic. “Additionally, the SEGGER debug probes enable the Atollic TrueVERIFIER unit test system, and the Atollic TrueANALYZER test quality measurement system, to test the embedded application in the target board, thus providing developers with an unrivalled tool solution for improving the software quality.”
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.
