Abstract

The invention discloses embedded device firmware and a firmware upgrading method and device.The embedded device firmware divides a root file system into two partitions, one partition is a miniRootfs partition, and the other partition is a rootfs partition; the mini Rootfs partition occupies extremely small space and only has a network function and an upgrading function; once the upgrade of the rootfs partition with the full function fails, the mini Rootfs partition is started to carry out upgrade recovery; moreover, a public module of the miniRootfs partition and a public module of the rootfs partition are extracted, and a public baseLibs library partition is set. In this way, under the condition of a small memory, the functions of the embedded device are not reduced, the flash space is saved, and therefore the production cost of products is reduced, it is guaranteed that firmware is rapidly and safely upgraded, and remedial measures can be executed when problems occur in firmware upgrading.

Description

technical field [0001] The present application relates to the technical field of embedded devices, in particular to an embedded device firmware, a method and a device for upgrading the firmware. Background technique [0002] Because of its small size, high reliability, strong function, flexibility and convenience, the application of embedded devices has penetrated into various fields such as industry, agriculture, education, national defense, scientific research and daily life. , product upgrading, accelerating the automation process, and improving productivity have played an extremely important role in promoting. Especially in the use of smart terminal electronic products more and more frequently, functions are often iterated, so firmware upgrades are becoming more and more important. [0003] However, embedded devices usually have high cost requirements, but the existing embedded devices not only have a harsh working environment, but also suffer from random power outages,...
