Also available to ARM developers are Atollic’s professional code-quality analysis and test-automation toolbox. The tool suite delivers a leap in software development team collaboration and developer productivity, and offers advanced features including ARM build and debug tools and Serial Wire Viewer (SWV) tracing. The fault analyzer feature within Atollic TrueSTUDIO’s debugger significantly aids embedded developers to quickly understand why the system has crashed thus improving productivity, speeding development time and quickening time to market.Ītollic TrueSTUDIO is a world-class development and debugging tool that offers a state-of-the-art editor, an optimizing C/C++ compiler and a multiprocessor-aware debugger with real-time tracing. By isolating the fault to an individual instruction allows the developer to reconstruct the MCU to the condition they were at the time the faulty instruction was executed. To further aid fault analysis, an exception stack frame visualization option provides a snapshot of MCU register values at the time of the crash. Memory errors can include attempts of access an illegal location or rule violations of the memory protection unit (MPU). Usage faults are the result of illegal instructions or other program errors. Bus faults occur when an invalid access attempt is made across the bus, either of a peripheral or memory location. Faults are categorized broadly into bus, usage and memory faults. The user can then view the reasons for the error condition.
Within the debugger, after a fault has occurred, the code line where the fault happened will be displayed. Typically, this may include division by zero errors, accessing invalid memory locations or accessing memory locations on misaligned boundaries. The fault analyzer feature interprets information extracted from the Cortex-M nested vector interrupt controller (NVIC) in order to identify the reasons that caused the fault. Added to the debugger, the fault analyzer functions aid developers to identify and resolve hard-to-find system faults that occur when the CPU has been driven into a fault condition by the application software. Jonkoping, Sweden, 9th January 2013 – Atollic® today announced the availability of a new fault analysis feature for the Atollic TrueSTUDIO IDE when developing C/C++ projects for ARM Cortex-M3 or Cortex-M4 microcontrollers.
