Vxworks Command Cheat Sheet |work| Guide

(running on your development station), these commands are essential for debugging, task management, and system interrogation. 1. Task Management & Information Manage the lifecycle and execution of real-time tasks. : Displays a synopsis of all running tasks in the system. sp (entryPt, args) : Spawns a task with default parameters. sps (entryPt, args) : Spawns a task and leaves it in a suspended state. td (taskId) : Deletes a specific task. ts (taskId) : Suspends a task. tr (taskId) : Resumes a suspended task. ti (taskId)

Here’s a detailed , focused on the most useful shell and kernel commands for day-to-day debugging, system inspection, and task management. VxWorks versions differ slightly (especially pre-6.x vs 6.x/7.x), but these commands work in most VxWorks shell (CMD mode) environments.

: Task Trace. Generates a stack backtrace, showing the chain of function calls leading to the current state. vxworks command cheat sheet

: Spawns a new task. taskSuspend : Pauses a running task. taskResume : Resumes a suspended task. taskDelete : Terminated a task and frees memory.

This quick reference guide covers common VxWorks shell (C interpreter) commands for task management, system diagnostics, and memory manipulation. Task Management Manage real-time tasks and execution flow: sp(entryPt, args) — Spawn a task with default parameters. sps(entryPt, args) — Spawn a task in a td(taskName|taskID) a specific task. ts(taskName|taskID) tr(taskName|taskID) a suspended task. System & Task Information Monitor system resources and task states: — Display a brief synopsis of all active tasks. ti(taskName|taskID) — Show detailed information from the Task Control Block (TCB) tt(taskName|taskID) — Show a stack trace for the specified task. checkStack(taskName|taskID) — Show the current stack usage for a task. (running on your development station), these commands are

Use these utilities to benchmark system performance, inspect hardware timers, and view the error log subsystem. C-Expression Shell (Csh) Command Shell (Cmd) Description checkStack; checkStack Analyzes all task stacks to verify safety margins. Show CPU Load spyReport; spy report

sysMemTop / memPartInfo — Inspect partitions and region sizes (implementation dependent). : Displays a synopsis of all running tasks in the system

Before diving into the commands, it is crucial to understand that the VxWorks shell operates in two distinct modes, each with its strengths.

: Spawn Task . Spawns a new task with default parameters and starts execution.
