Vxworks Command Cheat Sheet ((top)) ✦ Confirmed

In the world of real-time operating systems (RTOS), by Wind River stands as a titan. For over three decades, it has powered mission-critical systems: from the Mars rovers (Curiosity and Perseverance) and NASA’s James Webb Space Telescope to avionics systems, industrial robotics, and network infrastructure.

ifconfig — Configure and display network interfaces.

h [size] : Displays the command history or sets the history buffer size. reboot or CTRL+X : Restarts the target system.

: Displays a summary of all active tasks, including their IDs and status. sp(entryPt, arg1, ...) : Spawns a new task starting at the specified function. td(taskId) : Deletes a task by its ID or name. ts(taskId) : Suspends a task, pausing its execution. tr(taskId) : Resumes a suspended task. ti(taskId) vxworks command cheat sheet

Happy debugging. Keep your tasks running and your deadlines real-time.

Best practice: keep watchdog callbacks short and deterministic; use tick rate appropriate for timing resolution vs. CPU overhead.

: Searches the system symbol table for functions or variables containing the specified string. This is invaluable for finding "Show" routines. In the world of real-time operating systems (RTOS),

Spawns a new task with a designated name, priority, options, and stack size. taskSuspend(task_id) taskSuspend Pauses execution of the specified task. taskResume(task_id) taskResume Resumes a suspended task. taskDelete(task_id) taskDelete Terminates and deletes a task from the system. taskPrioritySet() taskPrioritySet

The VI editing mode (default) is optimized for low overhead, whereas Emacs mode offers GNU-like keybindings.

Before you fix anything, you need to know what is running and what hardware is present.

Memory & Register Modification Interact directly with memory addresses and CPU registers. d (address, n)

VxWorks relies heavily on multitasking. Monitoring task states, priorities, and stack usage prevents deadlocks and stack overflows. Task Monitoring
