Atollic TrueSTUDIO for ARM Helps Developers Achieve Highest Software Quality

Atollic announced recently the latest release of the Atollic TrueSTUDIO®integrated development environment. Incorporating many new features, Atollic TrueSTUDIO v4.1 aims to even further assist embedded developers to write code of the highest quality.

A significant feature added to TrueSTUDIO v4.1 includes the ability to record and display instruction trace data. Other features include the addition of automatic software unit testing within the optional TrueVERIFIER® add-module, and a test case debugger within the optional TrueANALYZER® add-on module.

The new instruction tracing function records the execution flow in real-time for later analysis. In this way, should an error occur it is possible to interrogate the trace logs and ascertain exactly what the processor was doing before a software error occurred. TrueSTUDIO v4.1 support ETM tracing using a Segger J-Trace JTAG probe, and ETB tracing for compatible ARM® Cortex™ devices using any of the supported JTAG probes, such as the Segger J-Link. The recorded instruction trace log can be displayed in either C mode, mixed C and assembler mode, as well as in pure assembler mode. The trace log has graphical annotations on execution branches, and can be exported to a file for offline analysis.

Other improvements to TrueSTUDIO includes an updated kernel aware RTOS debugging function that now supports the Quadros RTXC and the TOPPERS µITRON RTOS. With this feature, RTOS-based applications can be developed with complete confidence since the internal state of RTOS objects such as tasks, semaphores, queues and mailboxes can be displayed in the debugger.
