Problems solved by technology

Since the operating system kernel program, database program and driver program occupy a relatively large capacity and are not easily damaged, the cost of storing the above-mentioned programs will be very expensive, resulting in a waste of cost

Embodiment Construction

[0011] figure 1 Shown is a module diagram of the embedded device 10 in an embodiment of the present invention. In this embodiment, the embedded device 10 includes a Linux operating system. In other embodiments of the present invention, the embedded device 10 may also include other operating systems, such as Windows NT operating system.

[0012] In this embodiment, the embedded device 10 includes a program module 11 for storing working programs required for loading the Linux operating system, which includes a shared program submodule 110 , an application program submodule 111 and a backup application program submodule 112 . In this embodiment, the working programs stored in the program module 11 include operating system kernel programs (Kernel images), database programs (library images), driver programs and user application programs. In this embodiment, the program module 11 is a memory.

[0013] In this embodiment, the shared program sub-module 110 is used to store the kern...

Abstract

The invention relates to an embedded device, comprising a program module. The program module comprises a shared program submodule, an application program submodule and a backup application program submodule. The shared program submodule is used for storing a kernel program, a database program and a driver program of an operating system. The application program submodule is used for storing a user application program. The backup application program submodule is used for backing up the user application program. The invention also provides an embedded device loading method. The embedded device and the embedded device loading method not only reduce memories used for storing the kernel program, the database program and the driver program of the operating system, i.e. save memory cost, but also ensure that the kernel program, the database program and the driver program of the operating system only need to be called and run for one time when the embedded device loads the operating system, i.e. when the user application program is damaged, only a backup user application program needs to be called, and the kernel program, the database program and the driver program of the operating system do not need to be called and run again.

Description

technical field [0001] The invention relates to an embedded device. Background technique [0002] With the widespread use of the Linux system, the Linux system has attracted more and more attention. The Linux system includes a working program module, which is used to store the operating system kernel program (Kernel), database program (library), driver program and user application program . At the same time, the Linux system also includes a backup working program module for backing up programs in the working program module. Wherein, in the process of loading the Linux system, user application programs are often damaged. [0003] In the process of loading the Linux system, when calling and running all the programs in the working program module, if an error occurs in the user application program, then the Linux system can call and run all the programs in the backup working program module at this moment, that is Call and run operating system core program, database program, d...
