Making method of system mirror image and system installation method for electronic equipment

Abstract

The invention discloses a making method of a system mirror image and a system installation method for electronic equipment. The making method of the system mirror image includes the steps that system codes are written and include partition information and an expansion module, the partition information includes system partition information and user partition information, and the physical address of a user partition is located behind the physical address of a system partition; a label is set, stored in the system partition and used for being recognized when a system is started for the first time, and then the expansion module is triggered to carry out expansion operation on the user partition; the system codes and the label are backed-up to be the system mirror image. By the utilization of the making method of the system mirror image, edition development and verification time can be shortened, and the labor and material cost for testing and factory edition burning can be lowered.

Description

technical field [0001] The invention relates to the field of intelligent electronic equipment, in particular to a method for making a system mirror image and a system installation method for electronic equipment. Background technique [0002] During the production process of intelligent electronic equipment, the design unit of the intelligent operating system will hand over the designed system master image to the manufacturer, and the manufacturer will burn the system master image into the memory of the product to be produced for mass production product. [0003] The production method of the existing system master image is to make the corresponding master according to the size of the memory (EMMC) of the specific product. For example, for a product with 8G EMMC, an 8G master image is made; for a product with 16G , make a 16G master image, and so on. Then if the same type of product only differs in EMMC size, such as three products of 8G / 16G / 32G ROM, it is also necessary to...

Problems solved by technology

Then if the same type of product only differs in EMMC size, such as three products of 8G / 16G / 32G ROM, it is also necessary to make images of different sizes and send them to the factory, and the factory will burn them into different products in batches, for example, the 16G image The programming time is twice that of 8G, and the programming time of 32G is four times that of 8G, and the difference between them is only the size of the system user data partition and the size of the file system, which results in complex management and time-consuming constraints. Waste, which increases the complexity and time-consuming management of burning chips in the factory
