Abstract

The invention provides an automatic dual-system guide method of an embedded device. The method comprises the following steps: reading an environment variable; determining whether to guide from the current sub-area based on the read environment variable; if yes, guiding the embedded device from the current sub-area; if no, determining whether to switch to another sub-area; if yes, guiding the embedded device from the switched sub-area; and if no, starting a remote network to guide the embedded device.

Description

technical field [0001] The invention relates to an embedded device, and more particularly, to a dual-system automatic booting method of an embedded device capable of adopting dual-system backup and remote network download. Background technique [0002] Currently, embedded devices are widely used in electronic products. In current embedded devices, generally there is only one set of boot systems. Therefore, when the embedded device fails to start normally due to failure, the user cannot solve the problem by himself, and can only wait for the maintenance personnel to deal with it. [0003] For an embedded device using dual systems, when the system fails to start, the user also needs to intervene to switch the system manually. When both the primary system and the backup system fail, they can only wait for the maintenance personnel to deal with it. For the maintenance personnel, it is necessary to download the system software manually to repair the equipment, which makes the m...
