Vxworks Command Cheat Sheet

| Command | Description | |---------|-------------| | ifconfig | Show network interface config | | ifAddrSet <ifname>, <ip> | Set IP address (e.g., ifAddrSet "fei0", 192.168.1.10) | | routeShow | Show routing table | | ping <ip> | Send ICMP echo | | inetStatShow | Show all TCP/UDP connections | | arpShow | Show ARP cache | | tftpGet <host>, <filename>, <dest> | TFTP download | | tftpPut <host>, <src>, <filename> | TFTP upload |

VxWorks 7 introduced a newer, more modular shell with additional commands (often C++ aware).

| Command | Description | | :--- | :--- | | kernelVersion | Shows detailed kernel version info. | | moduleShow | Lists dynamically loaded modules (.out files). | | moduleUnload | Unload a module. | | rtpShow | Shows Real-Time Processes (RTPs) – VxWorks 7’s process model. | | rtpSuspend / rtpResume | Control RTP execution. | | devShow | Detailed device tree walk. |

Important: In VxWorks 7, you often need to prefix legacy commands with cmd (e.g., cmd "i") if you are in the new Python-based shell. vxworks command cheat sheet

| Command | Description | |---------|-------------| | help [command] | Show help (or help for specific command) | | print <value> | Print value (e.g., print 0x1234) | | printf "<fmt>", <args> | Formatted print (like C printf) | | logShow | Show system log messages | | timex <function> | Time execution of a function | | period <seconds>, <function> | Run function periodically | | repeat <count>, <command> | Repeat command N times |

| Command | Description | |---------|-------------| | intShow | Show interrupt vector usage (counts per vector) | | intConnect <vector>, <isr>, <arg> | Connect ISR to vector (shell use limited) | | excShow | Show exception handling vectors | | excHookAdd <func> | Add exception handler |

Real-time scheduling and timers are essential. VxWorks 7 introduced a newer, more modular shell

  • timer routines (sysClkRateGet / sysClkRateSet) — System clock configuration.

  • tickLib — Tick-related utilities.

    • Best practice: keep watchdog callbacks short and deterministic; use tick rate appropriate for timing resolution vs. CPU overhead. | Command | Description | |---------|-------------| | help
