Below is a comprehensive cheat sheet for the most essential VxWorks commands. 🛠️ Task and Process Management Manage and monitor tasks running on the kernel.
: Searches the system symbol table for symbols matching the string. : Displays a summary of system memory usage and statistics. moduleShow : Lists all downloaded or loaded object modules. printErrno(n) : Describes the specified error status value (use for the latest error). iosDevShow : Shows all loaded I/O devices. 3. Memory & Register Modification Interact directly with memory addresses and CPU registers. d (address, n)
Conclusion The VxWorks shell is a powerful on-target interface for real-time system control, debugging, and configuration. Mastering task management, memory and cache handling, device and network utilities, and synchronization primitives—along with careful attention to priorities, stack usage, and cache coherency—enables reliable and debuggable embedded systems development. The concise command categories and examples above provide a practical cheat-sheet-style overview for engineers working with VxWorks systems. vxworks command cheat sheet
