Embodiment 1

[0036] figure 1 The implementation process of the method for configuring the startup waiting time of the VxWorks operating system provided by the embodiment of the present invention is shown, and the details are as follows:

[0037] In step S101, the system is powered on, executes the boot code of the VxWorks operating system, and reads the startup configuration parameters of the VxWorks operating system.

[0038] In this embodiment of the present invention, the startup configuration parameters of the VxWorks operating system are stored in a non-volatile random access memory, such as NVRAM, in advance. The startup configuration parameters include not only startup configuration parameters of the VxWorks operating system in the prior art, but also startup waiting time.

[0039] In this embodiment of the present invention, the BOOT_PARAMS data structure may be used to store the startup configuration parameters of the VxWorks operating system. In the original design of the exist...

Embodiment 2

[0076] figure 2 The structure of the device for configuring the startup waiting time of the VxWorks operating system provided by the embodiment of the present invention is shown, and only the parts related to the embodiment of the present invention are shown for convenience of description.

[0077] The device can be used for the VxWorks operating system or other computers using the VxWorks operating system. It can be a software unit, a hardware unit or a combination of software and hardware running on these VxWorks operating systems, or it can be used as an independent pendant Integrate into the VxWorks operating system or run on the application system or device of the VxWorks operating system, where:

[0078] The system boot unit 1 executes the boot code of the VxWorks operating system after the system is powered on, and reads the startup configuration parameters of the VxWorks operating system.

[0079] In the embodiment of the present invention, the startup configuration ...

Abstract

The present invention is applicable to the computer field, and provides a VxWorks operating system and a method and device for configuring its start-up waiting time. The method includes: powering on the system, executing the boot code of the VxWorks operating system, and reading the start-up configuration parameters; Configure parameters to obtain the startup waiting time; if a button interrupt command is received before the startup waiting time countdown ends, when the configuration parameter modification command input by the user is received, the startup waiting time in the startup configuration parameter is updated, and the system image is received After loading the command, load the image file of the VxWorks operating system; if the button interrupt command is not received before the end of the start waiting time countdown, when the end of the start waiting time countdown, load the image file of the VxWorks operating system. The method provided by the invention can dynamically and flexibly configure the startup waiting time of the VxWorks operating system.

Description

technical field [0001] The invention belongs to the field of computers, and in particular relates to a VxWorks operating system and a method and device for configuring the startup waiting time of the VxWorks operating system. Background technique [0002] VxWorks operating system is an embedded real-time operating system (RTOS), which is widely used in communications, military, aviation, aerospace and other high-end, high-quality real-time requirements due to its good reliability and excellent real-time performance. technology fields, such as satellite communications, military exercises, missile guidance, aircraft navigation and other fields. [0003] Generally speaking, the VxWorks operating system includes boot codes and system images. The boot codes can be bootrom generated by source code compilation under the VxWorks operating system, or u-boot. The main function is to initialize the least hardware units so that VxWorks can be loaded. System image of the operating syste...
