Problems solved by technology

[0007] At present, this method of determining the kernel startup parameters in the boot compilation stage has an obvious deficiency, that is, the boot must be recompiled whenever the kernel startup parameters need to be modified; When multiple versions of the system require different kernel startup parameters, the boot version cannot be unified, which increases the cost of product maintenance

Abstract

The invention discloses a method, a system and a device for realizing guide of an operating system kernel. The method comprises the steps of: writing a kernel start parameter into a compiled configuration file, packaging the configuration file with the operating system kernel into a version packet, storing in a version machine of a wireless base station system; and after electrifying the wireless base station system, guiding a loading program to analyze the configuration file from the version packet downloaded from the version machine, setting an environment variable according to the configuration file, and writing the kernel start parameter extracted from a range of the environment variable into a memory region. The invention realizes the demand of products of various systems on the kernel function difference through changing the configuration file, thereby greatly enhancing maintainability of a boot version and being easier to realize smooth switching and evolution among multi-system base station systems.

Description

technical field [0001] The invention relates to a method for guiding the kernel of an embedded linux system in a wireless communication product, in particular to a method, a system and a device for realizing guiding of the kernel of an operating system. Background technique [0002] With the development of mobile communication technology, it has become a trend for multiple wireless communication standards to share hardware and software platforms, thereby greatly reducing costs, thereby achieving smooth switching and evolution among multiple wireless communication standards. [0003] In the software development of wireless base stations, the linux operating system is used more and more widely. The open source U-boot boot loader (hereinafter referred to as U-boot) developed by German engineer Woldgang Denk is a program commonly used to guide the kernel of the Linux operating system in embedded systems. The U-boot supports processors with multiple architectures, and has been a...
