Embodiment Construction

[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0038] At present, for embedded system products, iterative upgrades with user needs and software versions are common basic functions during use. At the same time, embedded devices usually have high cost requirements, but the working environment is harsh, random power off, small memory, and small flash space , There may be no external storage and other resource constraints that bring many challenges to the upgrade. If the upgrade is not handled proper...

Abstract

The invention discloses an embedded system upgrading method and device, equipment and a medium. The method comprises the steps that a FLASH of a to-be-upgraded embedded system is divided into different partitions, and the partitions comprise a plurality of system program partitions and an upgrading backup partition; determining an upgrade partition from the system program partitions, and packaging and backing up the upgrade partition to the upgrade backup partition; and when the upgrading partition is successfully upgraded, clearing data in the upgrading backup partition, and upgrading a non-upgraded partition in the system program partition. In this way, the problem that products on the embedded system cannot be used due to the abnormal problem occurring in the upgrading process of the embedded system can be solved, and it is guaranteed that the embedded system can be normally used.

Description

technical field [0001] The present application relates to the field of embedded technology, in particular to an embedded system upgrade method, device, equipment, and medium. Background technique [0002] For embedded system products, iterative upgrades with user needs and software versions are common basic functions during use. At the same time, embedded devices usually have high cost requirements, but the working environment is harsh, random power off, small memory, small flash space, and possible Resource constraints such as lack of external storage bring many challenges to upgrades. If the upgrade is not handled properly, the embedded device will become a brick, making the products on the embedded system unusable. [0003] Therefore, it is an important problem for those skilled in the art to solve the problem that an abnormality occurs during the upgrading process of the embedded system and the products on the embedded system cannot be used. Contents of the invention ...
