Abstract

The invention discloses an embedded board operating system backup startup method and an embedded system. The embedded board includes a board chip, and the board chip is connected to at least two storage media for communication, and each storage medium is a QSPI storage medium or EMMC storage medium, and each storage medium is installed with an operating system, one of which is the main medium, and the rest are backup media, the operating system on the main medium is the main system, and the operating system on the backup medium is the backup system; The method for backing up the operating system of the embedded board includes the following steps: after the embedded board is powered on, the main system is controlled to start; whether the main system is successfully started is detected; when the main system fails to start, the backup system is controlled to start. The technical solution of the present invention aims at avoiding the problem in the prior art that the operating system of the embedded board cannot be started due to abnormality of the storage medium.

Description

technical field [0001] The invention relates to the technical field of embedded board operating systems, in particular to an embedded board operating system backup startup method and an embedded system. Background technique [0002] The embedded board is a computer single board with a 3U VPX structure, and its operating system is a linux kernel, and the operating system is usually stored in a storage medium. Compared with the common desktop operating system, the operating system of the embedded board has the characteristics of compactness. The system can be installed using a storage medium with a smaller capacity. Generally, the capacity of the storage medium is required to be between several MB and several GB. The storage medium is generally firmly soldered to the motherboard. [0003] The operating system of the embedded board generally does not have a graphical desktop and cannot provide a user interface. In the event of a system startup failure, the desktop environme...
