Partition image online upgrade method, device, device and medium of terminal equipment

Abstract

This application discloses a partition image online upgrade method of a terminal device. After determining the adjusted partition, first, the kernel update image and the Rootfs update image are backed up to the App partition to form two mutually backed-up Kernel and Rootfs partitions, and then Write the kernel update image and Rootfs update image to the merged partition, and then write the update of the App update image after the writing is completed. At the same time, mark the corresponding stages in each execution stage of the upgrade. In the case of abnormal restart such as power failure , according to the stage mark in the interactive partition, and the two mutually backed up Kernel and Rootfs partition mirrors, it can ensure that the system can perform remote upgrade again and ensure the stability of the system operation. The present application also provides an online upgrade device, device and a readable storage medium for a partition image of a terminal device, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the technical field of computer software, in particular to a method, device, device and a readable storage medium for online upgrade of a partition image of a terminal device. Background technique [0002] The Flash space (partition) layout of a terminal device (such as a camera) using Linux mainly includes: uboot, kernel, root file system (hereinafter referred to as Rootfs area), and business file code area (hereinafter referred to as App area). Due to the hardware characteristics of most CPUs, the CPU partially loads the uboot code from the fixed Flash, and upgrading uboot has unsafe features, so after the device leaves the factory, uboot will not be upgraded, but the kernel, Rootfs, and App three areas need to be upgraded after the device leaves the factory , and in order to maintain product upgrade management, usually these three partitions need to be updated at the same time. During the remote upgrade operation,...

Problems solved by technology

[0004] In the above method, capacity or equipment needs to be added, and the additional capacity and equipment need additional cost, resulting in an increase in the overall implementation cost; or the cooperation of the user (removing equipment or performing some complex operations) is required, which requires high technical requirements for the implementation personnel , which is not conducive to widespread promotion, and the user cooperation process is prone to errors, resulting in the failure of the upgrade process, which affects the stability of the system operation
