Embodiment Construction

[0040] Hereinafter, preferred embodiments of the present invention are given in conjunction with the drawings to illustrate the technical solutions of the present invention in detail.

[0041] This embodiment takes an embedded dual system as an example for description.

[0042] Such as figure 1 As shown, the entire flash memory space of the embedded device is divided into four parts. The first part is used to store the bootloader. The second part is used to store data related to the first operating system, including the global structure image tag1 used to record the detailed information of the first system image corresponding to the first operating system and the first operation The root file system and kernel of the system. The third part is used to store the data related to the second operating system, including the global structure image tag2 used to record the detailed information of the second system image corresponding to the second operating system and the second operation...

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 invention relates to a multi-system booting method, in particular to a method for making a multi-system mirror file, a mirror file made by the making method, and a multi-system implementation using the mirror file Start the boot 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 normally due to various possible reasons, it is difficult for users to solve this type of system crash, and they 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 fails to boot the first system image, the user needs to use the serial tool to intervene, such as telling the location of the second system image in the bootloader system and whether to start th...
