Embodiment Construction
[0027] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0028] The invention provides a remote upgrade method of an embedded system, which is used to realize the remote upgrade of a server to a host, wherein the host refers to a hardware device installed with an embedded system, for example, a hardware device installed with a Linux embedded system. The invention provides The remote upgrade method of the embedded system, the main idea is: divide the system files into multiple categories according to the functions, the host partitions its storage medium, and the storage medium stores various system files by partitioning, for exa...

The invention provides a remote upgrading method of an embedded system. The method comprises the following steps: a host computer partitions a storage medium, and divides the storage medium into a boot file area, a kernel file area, a file system area, an application program area and an erasing protection area; The server sends the upgrade instruction to the host computer; The host downloads the corresponding upgrade data packet; The host computer checks the integrity of the downloaded upgrade packets, the host computer checks the file format of the upgrade packets, the host computer automatically restarts, and enters the upgrade program. The invention has the advantages that the host computer stores the boot files, the kernel files, the file system and the application programs of the embedded system in different partitions by partitioning the storage medium, so that the different partitions can be upgraded independently when the remote upgrading is performed, so as to reduce the dataquantity of the transmission upgrading package and reduce the operation complexity. Especially when the large number of hosts are upgraded remotely, the method can avoid network congestion and improvethe upgrade speed and efficiency.
Description
technical field [0001] The invention belongs to the technical field of system upgrading, and in particular relates to a remote upgrading method of an embedded system. Background technique [0002] Embedded systems are widely used in various information collection and automatic control fields. Embedded systems are usually located far away. Therefore, network-based remote upgrade methods are generally used. [0003] In the traditional remote upgrade method for embedded systems, the server needs to transmit the latest version of the application installation package to the host computer installed with the embedded system through the network, and the transmitted application installation package is a complete embedded system file, with The problem of large amount of transmitted data and complicated operation process is not conducive to the remote upgrade of the host. Contents of the invention [0004] Aiming at the defects in the prior art, the present invention provides a remo...
