Embodiment Construction

[0049] Explanation of related terms:

[0050] vxWorks: The vxWorks operating system is an embedded practice operating system (RTOS) designed and developed by Wind River Corporation of the United States in 1983. It is a key component of the embedded development environment. The operating system has good sustainable development capabilities and a high-performance kernel. As well as a friendly user development environment, it occupies a place in the field of embedded real-time operating systems;

[0051] out file: belongs to the ELF file type, it can be loaded to the file system (for example, using the copy command to load to the RAM disk) through the ftp tool, and then call the ld or loadModule function to load and run in the operating system;

[0052] loadModule: a system interface function provided by the vxWorks operating system, used for loading target files;

[0053] ld: The system interface function provided by the vxWorks operating system, used for loading the target fil...

Abstract

The invention discloses a method, a device and a system for loading an out file. The method disclosed by the invention comprises the following steps of reading an out file to be loaded in a memory from a storage; calling a vxWorks system function memDrvCreate(), and constructing the out file in the memory to form a pseudo I / O equipment file; and calling a vxWorks system function loadModule() to load the pseudo I / O equipment file, thus loading the out file. According to the invention, the out file is read in the memory from the storage; the out file in the memory is made into the pseudo I / O equipment file by utilizing a system function memDevCreate(), so that the pseudo I / O equipment file can be called by the loadModule() function, and therefore, loading of the out file is completed; a file system is unnecessary to use; the storage space of the storage can be effectively saved; and furthermore, the problem that the out file is lost or damaged due to the fact that the file system is damaged can be avoided.

Description

technical field [0001] The present application relates to the field of embedded technology, in particular to an out file loading method, device and system. Background technique [0002] The module executable file of the embedded vxWorks operating system is an out file, similar to the exe executable file in the Windows environment, and the out file is the target file format in the embedded vxWorks operating system environment. The embedded vxWorks operating system uses the out file module to release software, which is conducive to code confidentiality and system tailoring. [0003] In the traditional embedded vxWorks operating system, the loading of out files depends on the file system built based on the embedded vxWorks operating system. The loading of out files is to put each out file under the file system, and load the out files according to the configuration file when starting Or fix the loading and order of out files in the startup code. [0004] Usually, the resources...
