# FreeRTOS

## Contract

| Field | Bound contract |
|---|---|
| Trigger | A FreeRTOS application needs tasks, inter-task communication, stack overflow detection, a `FreeRTOSConfig.h`, or thread-aware debugging through OpenOCD and GDB. |
| Authority | Reversible local: writes only the application sources and `FreeRTOSConfig.h` in the project directory the user names; rollback is reverting those files in version control. No remote mutation. |
| Side effect | New or edited C sources and configuration in the project. A debug session halts and resumes the target. |
| Done | The scheduler starts, every task runs at its intended priority, shared resources are guarded by a mutex, `configCHECK_FOR_STACK_OVERFLOW` and `configASSERT` are on with hooks that stop the core, and `info threads` in GDB lists the tasks. |

## Inputs

- FreeRTOS kernel version (`tskKERNEL_VERSION_NUMBER` in `task.h`; V11.3.1 is the current release on 2026-09-05).
