IAR Systems boosts debugging and trace capabilities for ARM developers

JTAGjet-Trace is an in-circuit debugging probe with advanced trace features for complex application development. With support for Embedded Trace Macrocell, it provides developers with complete insight into their application’s behavior. Users can observe the effect of the program as it executes on the board and use techniques such as full instruction trace and function profiling to identify problems in the application. JTAGjet-Trace is based on the JTAG boundary scan port and can perform trace acquisition of up to 200MHz trace clock (400Msample/sec ETM trace acquisition speed) with a trace buffer capture capacity of up to 18MB. Auto-adjusting timing eliminates problems with data and clock skew, and 56-bit time stamping provides CPU cycle accuracy down to 5ns.

IAR Embedded Workbench now also supports the possibility of simultaneously connecting multiple serial wire debug devices. This considerably simplifies debugging of ARM Cortex multicore devices. By connecting to multiple cores on the same device at the same time, the complete multicore application can be concurrently debugged.

“The demand for extended debugging and trace possibilities is high,” confirmed Mats Ullström, Director of Products and Services, IAR Systems. “With the integration of JTAGjet-Trace, we offer expanded trace functionality, and continue to supply our existing and new customers with high-quality, well-integrated tools. By combining the advanced debugging functionality in IAR Embedded Workbench with JTAGjet-Trace, users gain new possibilities for powerful debugging with trace.”

IAR Embedded Workbench is a complete C/C++ development tool suite for embedded applications, including high-performing build tools and the comprehensive IAR C-SPY Debugger. Recognizing the importance of providing simplified, seamless development workflows, IAR Systems purchased Signum Systems in 2011 and now offers a product portfolio of completely integrated in-circuit debugging probes. In addition to JTAGjet-Trace, the portfolio includes I-jet, which offers full power profiling for all ARM cores. All products are delivered with access to IAR Systems’ extensive technical support.

JTAGjet-Trace is available in a specific ARM Cortex-M edition, as well as a full edition with support for all ARM7, ARM9, ARM11, Cortex-M, Cortex-A8/A9 and Cortex-R4 cores equipped with ETM trace logic.
