Problems solved by technology

The main problem of this system-wide upgrade method is that the upgrade time is relatively long, which may last tens of seconds to several minutes. If the embedded device encounters a sudden power failure or other reasons during the upgrade process, the entire system will not be able to recover. The manufacturer needs to reprogram the system
For embedded devices placed in the suburbs or high places (such as various monitoring devices), the repair cost of the system due to upgrade failure will be even higher

Embodiment Construction

[0037] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0038] see figure 1 , the present invention relates to a kind of embedded equipment system upgrading method, it comprises steps,

[0039] A), load the upgrade package to the upgrade partition, and store the obtained upgrade package in the upgrade partition;

[0040] B) Create an upgrade logo in the upgrade partition;

[0041] C), system restart;

[0042] D), start the boot loader;

[0043] E), mount the upgrade partition in the boot loader;

[0044] In this step, the upgrade partition can be mounted through related commands in the bootloader.

[0045] F), the boot loader checks whether there is an upgrade logo in the upgrade partition, if so, continue the steps, otherwise start the system normally;

[0046] G), verify the upgrade pac...

Abstract

The invention provides a method and a device for upgrading an embedded device system. Different from the traditional method for upgrading the system after starting the operation system, the method is characterized in that the upgrading is completed through a preliminarily-started boot loader program of the embedded device system, the upgrading flow can be restarted repeatedly and safely as long as the boot loader program is not damaged in the upgrading process even when the upgrading process encounters the problems such as power failure and errors, so that the upgrading can be enabled to be successfully completed.

Description

technical field [0001] The invention relates to the field of embedded system processing, in particular to a method and device for upgrading an embedded device system. Background technique [0002] Existing embedded systems are composed of multiple parts, including boot loader (bootloader), kernel, root file system and application programs. These four parts are usually in separate partitions. When existing embedded devices need to be upgraded , usually after the system is started, that is, the upgrade operation is performed after the operating system is up. In this way, when the system is upgraded, the four partitions will be erased in sequence, and the upgraded firmware will be written to the corresponding partitions. The main problem with this system-wide upgrade method is that the upgrade time is relatively long, which may last tens of seconds to several minutes. If the embedded device encounters a sudden power failure or other reasons during the upgrade process, the enti...
