FreeRTOS™, from Real Time Engineers Ltd, is a popular real time operating system (RTOS) that is free to use in commecial products and supports ARM7, ARM9 and Cortex-M microcontrollers. The ARM® DS-5™ toolchain users can benefit from in-built task-aware debugging and visibility into internal data structures of FreeRTOS.
Integrated Debug Control
DS-5 Debugger has full visibility of processor cores, tasks and call stack. The Debug Control view displays all this information in an intuitive layout, on a per debug connection basis, making it extremely easy for you to identify the current context and switch between stack frames. Additionally, also DS-5 breakpoints are customized for the specific OS, enabling task-specific conditions for breaking the execution.
FreeRTOS Data Views
The OS Data view in DS-5 offers great flexibility for visualization of internal FreeRTOS data structures. As is standard to most DS-5 views, you can view as many instances of the OS Data view as necessary. Each of them can be configured to display different pieces of information about the internal kernel state. For instance, you can select to simultaneously see the lists of tasks, queues and more.
