Atollic adds fault analysis feature to TrueSTUDIO debugger for ARM Cortex-M3/M4 microcontrollers
Atollic today made available a new fault analysis feature for the Atollic TrueSTUDIO IDE when developing C/C++ projects for ARM Cortex-M3 or Cortex-M4 microcontrollers. 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.The
Within the debugger, after a fault has occurred, the code line where the fault happened will be displayed. The user can then view the reasons for the error condition. Faults are categorized broadly into bus, usage and memory faults. Bus faults occur when an invalid access attempt is made across the bus, either of a peripheral or memory location. Usage faults are the result of illegal instructions or other program errors. Memory errors can include attempts of access an illegal location or rule violations of the memory protection unit (MPU).
To further aid fault analysis, an exception stack frame visualization option provides a snapshot of MCU register values at the time of the crash. 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.
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.
Atollic 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. 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. Also available to ARM developers are Atollic’s professional code-quality analysis and test-automation toolbox. Atollic TrueSTUDIO also includes static source code analysis with MISRA-C compliance checking and code metrics features.
Complementing Atollic TrueSTUDIO are a family of code analysis and validation tools. Atollic TrueANALYZER facilitates in-target test quality measurement using MC/DC-level coverage using dynamic execution flow analysis. Finally, Atollic TrueVERIFIER provides an embedded test automation function using auto-generated and auto-executed unit test suites on the target board.
