Simple and convenient log recording method for VxWorks operating system system

Abstract

The invention relates to a simple and convenient log recording method for a VxWorks operating system system, and belongs to the field of embedded software development. The method comprises the following steps: adding a system log library source file logLib.c attached to a VxWorks operating system development environment into a VxWorks Image project; modifying logLib.c in a VxWorks Image project, and adding a mounting point of a self-defined log processing function into the logLib.c; developing a related system log recording program on the basis of the function format of the self-defined mounting point, and integrating the related system log recording program into a VxWorks Image project; and modifying the compiling sequence of each source file in the VxWorks Image project, moving the logLib.o to the forefront, and compiling and running the VxWorks Image project. According to the log recording method for the VxWorks operating system, related configurations such as write-in frequency, error processing and timeout of logs can be simply and conveniently controlled, a user-defined log recording function can be easily achieved, and the invention is simple in configuration, low in cost, high in safety and capable of being conveniently used.

Description

technical field [0001] The invention belongs to the field of embedded software development, and in particular relates to a simple VxWorks operating system system log recording method. Background technique [0002] System logs are important data for recording and analyzing the running process of the operating system. As a commonly used operating system in the embedded field, VxWorks operating system provides its own system log library LogLib, and can mount standard file IO file descriptors in the log library to write system logs into persistent storage such as hard disk, media such as memory cards. [0003] However, the file writing function of the system's built-in log library does not provide configuration properties about writing frequency, error handling, etc., which is very inconvenient to use. If the user wants to customize the file writing method of the system log, there are two general methods. The first is to customize the VxWorks Source Build project, edit and mo...
