Embodiment approach

[0061] As an implementation manner, the detection module 302 detects whether the single board of the program to be output is the master control board or the slave control board, specifically:

[0062] Obtain the identification number of the single board of the program to be output;

[0063] It is judged according to the identification number whether the single board of the program to be output is the master control board or the slave control board.

[0064] As another implementation manner, the detection module 302 detects whether the single board of the program to be output is the master control board or the slave control board, specifically:

[0065] The type and model generated by the single board that receives the program to be output;

[0066] It is judged according to the type signal whether the single board to output the program is the master control board or the slave control board.

[0067] The compilation module 301 loads the corresponding kernel program to the mai...

Abstract

The invention relates to the technical field of embedded type systems, and provides a method for dynamically loading programs of a kernel module of an embedded type system. The method comprises the following steps of compiling a kernel program for a main control board and a kernel program for an auxiliary control board; detecting whether a single board of a to-be-outputted program is the main control board or the auxiliary control board; when the single board is the main control board, loading the corresponding kernel program into the main control board; when the single board is the auxiliary control board, loading the corresponding kernel program into the auxiliary control board, adopting the dynamic kernel module loading scheme, and detecting the type of the single board, so as to enable the one-time compiling program to run on different single boards of the same hardware platform or on different versions of single boards. The method has the advantages that the version maintenance cost of the kernel programs is reduced, and the development efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of embedded systems, in particular to a method and device for dynamically loading a program of an embedded system kernel module. Background technique [0002] For embedded systems, kernel modules are generally loaded by defining precompiled macros. For example, in LINUX and VXWORKS systems, the kernel module decides whether to compile a particular module into the kernel and load it when the system is running through precompiled macro definitions. Among them, the precompiled macro definition is a static implementation method, and the behavior of the kernel has been determined during the compilation period, and cannot be modified after the compilation is completed. Under the same hardware platform, when there are multiple versions, it is necessary to maintain a set of compilation switches to compile the kernel files of each version separately, and at the same time, the kernel files of each version can only be...
