Abstract

The invention relates to the technical field of FOTA upgrading, and discloses an FOTA upgrading method based on a small space. The method comprises that: a first differential packet, a second differential packet and a third differential packet which are used for upgrading an intelligent terminal are obtained; the first differential packet, the second differential packet and the third differential packet are uploaded to an OTA server; the OTA server sends an instruction to the intelligent terminal to detect the size of the space, and returns the instruction to detect whether upgrading is carried out or not; if yes, an upgrading instruction is sent to the intelligent terminal by the OTA server, and a corresponding upgrading package is prepared; if the OTA server detects that the space of the intelligent terminal is a small space, the plurality of compressed packages in the first differential package are downloaded to the corresponding space of the intelligent terminal in sequence, and independent upgrading is carried out; after the current compressed packet in the first differential packet is successfully upgraded, a flag is sent to the OTA server to download a next compressed packet; and after the last compressed package in the first differential package is successfully upgraded, the upgrade package automatically deleted. Small-space upgrading of the intelligent terminal is facilitated.

Description

technical field [0001] The invention relates to the technical field of FOTA upgrading, in particular to a FOTA upgrading method based on a small space. Background technique [0002] The FOTA upgrade (Firmware Over-the-Air) technology mainly refers to a technology for remotely managing and updating firmware in a terminal device through an air interface. Through the FOTA upgrade operation, not only the application software can be downloaded and upgraded, but also the operating system of the device can be updated. In this way, the FOTA upgrade operation enables the device manufacturer to send the upgrade package to the user's terminal device through the network, thereby upgrading the firmware and software, which not only facilitates the user, but also saves costs for the device manufacturer. [0003] In the prior art, many embedded devices have very strict space requirements, and some have only a few M space. However, before development, it is necessary to reserve space for f...
