Image file, method for making the image file, and method for starting and guiding multiple systems

Abstract

The invention discloses multisystem image file producing method, an image file and a multisystem start guiding method. The producing method comprises the following steps: S11, producing a bootloader, and writing the bootloader into an object file; S12, establishing a corresponding global structure for one operating system corresponding to the unestablished global structures in a plurality of operating systems of a multisystem; S13, writing the global structure established in the S12, and a root file system and core of the operating system corresponding to the global structure into the object file; and S14, judging whether the global structures are established for all global structures correspondingly or not, if yes, taking the object file as an image file and finishing the flow, otherwise, executing the S12 again. According to the invention, intelligent start guiding of the systems can be realized, and further the stability and maintainability of the system can be obviously improved.

Description

technical field [0001] The present invention relates to a method for starting and guiding a multi-system, in particular to a method for making a multi-system image file, an image file produced by the method, and a multi-system system implemented by using the image file. Start the bootstrap method. Background technique [0002] At present, embedded devices are widely used in various industries. However, most of the current embedded devices only have a single system. Therefore, when the embedded device fails to start the system normally due to various possible reasons, it is difficult for the user to solve the problem of the system crash, and the user can only hope that the corresponding maintenance personnel can handle it. [0003] However, for some embedded devices with dual systems, the situation is not satisfactory. [0004] After the bootloader (bootloader) fails to guide the first system image, the user needs to intervene with the help of serial port tools, such as te...
