Abstract

The invention relates to an embedded software multi-version control system and method, and belongs to the technical field of vehicle electronic information systems. According to the invention, a plurality of independently published versions of application software are integrated into the program memory; the selection of the application software version is realized by starting the bootstrap program, so that the switching of the working state of the product in the same software through complex judgment logic is avoided, the basic reliability of the software is improved, the development cost andthe later manual maintenance cost can be saved to a great extent, and the method has important engineering application value and economic benefit. The method can be implemented in various embedded chips, and the system adaptability is good; a plurality of application program versions can be added and switched, the expandability is good, and the reliability of software is ensured.

Description

technical field [0001] The invention belongs to the technical field of vehicle electronic information systems, and in particular relates to an embedded software multi-version control system and method. Background technique [0002] With the rapid development of electronic technology, more and more embedded products have begun to penetrate into every corner of our lives. From tiny smart sensors to vehicle systems to large-scale industrial production systems, embedded products all play an extremely important role. The role of the core, etc. In the application process of embedded products, in order to reduce development costs, it is often necessary to reuse products, typically as follows: [0003] 1) Increased product reliability. When a released product has a reliability problem, but the function has no impact, after the test is confirmed, the reliability increase of the product needs to be implemented. For products with increased reliability, the general requirement that m...
