Embodiment Construction

[0028] The specific process of the remote software update method proposed by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] The realization of the scheme of the present invention is divided into two stages—that is, the U-boot customization before the deployment of sensor nodes and the software update stage after the deployment of the entire sensor network.

[0030] (1) Before deploying each node, customize U-boot and write it into the memory of the node;

[0031] (2) After deployment, use the supporting development tool chain to compile and generate the software image file used for updating, send update instructions to each node of the sensor network through the background server, and update the software of the non-U-boot part on each node in turn, so that Realize the software update of the whole sensor network node.

[0032] Technical scheme of the present invention is specifically as follows:

[0033] U-boot ...

Abstract

Disclosed is a remote software updating method. Under the environments of target hardware and U-boot guiding software, a software image is downloaded to the target hardware in a remote communication mode, and software updating, on the target hardware, of non-U-boot parts comprising operation systems and application programs is realized. According to the remote software updating method, updated software version record management and software updating state management, in wireless networking, of all nodes with identical hardware configuration are realized in upper computer software. By the application of the remote software updating method, updating, at target hardware nodes, of the operation system and the application program can be realized under specific target hardware environments, the manual operation of conducting software updating on each hardware point is avoided, the workload of development personnel and maintenance personnel is effectively reduced, and the operation cost and the maintenance cost are lowered.

Description

technical field [0001] The invention belongs to the fields of computer embedded software and the Internet of Things, and in particular relates to a method for remotely updating software on multi-node hardware of the Internet of Things based on U-boot. Background technique [0002] Software update means that when the software developer writes the software, because the designer does not consider comprehensively or the program function is not perfect, after the software is released, after the software is released, the program is modified or new functions are added, and the software is released again and deployed to the target system. the process of. [0003] U-boot, or Universal BootLoader, is an open source system boot software. Developed from the open source project PPCBoot, ARMboot is incorporated into PPCBoot, and it is collectively called U-Boot with some other arch loaders. The first version U-Boot-0.2.0 was released on December 17, 2002. U-Boot provides two modes of o...
