Atollic has announced the latest release of the Atollic TrueSTUDIO integrated development environment. Atollic TrueSTUDIO v4.1 aims to assist embedded developers to write code of high quality.

A significant feature is 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 instruction-tracing function records the execution flow in real time for later analysis. 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.

The product supports ETM tracing using a Segger J-Trace JTAG probe and ETB tracing for compatible ARM Cortex devices using any of the supported JTAG probes. The recorded instruction trace log can be displayed in either C mode, mixed C and assembler mode and pure assembler mode. The trace log has graphical annotations on execution branches and can be exported to a file for offline analysis.

Other improvements include an updated kernel-aware RTOS debugging function that supports the Quadros RTXC and the TOPPERS µITRON RTOS. 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.
