Embodiment Construction

[0045] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0046] At present, the disadvantage of this solution is that it needs a transit flash storage area. After the upgrade package is loaded into the flash, the system needs to be restarted to make the upgrade package take effect. Execute uboot-kernel (kernel)-root file system, that is to say, the upgrade time needs to add the time required for downloading to the time required for loading...

Abstract

The invention provides an upgrading method and device. The method includes: sending a confirmation response message to a host computer if an upgrading request sent by the host computer is received, wherein the upgrade request contains information of a to-be-upgraded partition; if the upgrading package sent by the host computer is received, writing the upgrading package into the to-be-upgraded partition corresponding to the information of the to-be-upgraded partition; and sending upgrading completion information to the host computer, and restarting a system. Technical effects that the upgrade package is directly written into the to-be-upgraded partition, time of loading the upgrading package from an SD card into flash can be omitted, and thus a technical effect of shortening upgrading timecan be realized are realized.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an upgrading method and device. Background technique [0002] At present, the UAV software upgrade solution of the Linux system is to obtain the upgrade package from the server to the SD card through network transmission, check whether there is an upgrade package in the SD card after restarting the system, and then load the upgrade package to the corresponding flash partition. [0003] The disadvantage of this solution is that a transit flash storage area is required. After the upgrade package is loaded into the flash, the system needs to be restarted to make the upgrade package take effect. After restarting, it will execute the unique steps that all Linux systems will execute: first execute uboot –kernel (kernel)-root file system, that is to say, the upgrade time needs to add the time required for downloading to the time required for loading, and the upgrade tim...
