Problems solved by technology

Traditional tablet computers only support the startup of a single system, that is, only carry Android system or Linux system, and cannot take into account the advantages of both systems to provide developers and users with the convenience of applications
However, the existing embedded boards are either only equipped with a single operating system, or need to perform complex dual-system implantation operations to achieve dual-system startup. This type of dual-system implantation operation is not only costly, but also generally At the expense of some functions in the original system

Embodiment Construction

[0022] The scheme of this application is further described in conjunction with the accompanying drawings as follows:

[0023] A method for realizing dual operating system startup on an embedded board, comprising

[0024] Initial setup steps:

[0025] 1) Install the Android system on the embedded board, establish a BOOT partition with the Android kernel and boot system, a RECOVERY partition with the Android kernel and emergency system, an idle BACKUP partition, and a MISC partition for partition boot settings.

[0026] 2) Move the Android emergency system in the RECOVERY partition to the BACKUP partition, and write the Linux kernel and its boot system in the RECOVERY partition;

[0027] 3) The boot command pointing to the Android system is written in the system MISC partition by default, so that the embedded board loads the Android system by default;

[0028] System switching steps:

[0029] 1) Operate under the Android system, rewrite the boot command in the MISC partition ...

Abstract

In order to implement startup and switching of both an Android system and a Linux system on an embedded board card, the present invention discloses a method for starting double operating systems. The method comprises the operation steps of an initial setting step, a system switching step and a reduction start-up step. Particularly, the method comprises: transferring a rescue system in a Recovery partition of the Android system to another idle partition, such as a backup partition; writing into a kernel and a booting system of the Linux system; and by modifying a script command of an MISC partition, guiding to switch and load the Android system and the Linux system. According to the method disclosed by the present invention, minimum modification on the systems is ensured, the problems of trouble transplanting process, high cost and the like of a dual-system startup mode are solved, the embedded board card supports the dual systems and retains an emergency mode of the Android system, and the Android system can carry out operations of restoring factory settings, OTA upgrading and the like.

Description

technical field [0001] The invention relates to a method for realizing dual operating system startup on an embedded board. Background technique [0002] Embedded boards equipped with an Android operating system (hereinafter referred to as Android boards) are widely used, including display driver boards, tablet computers, TV boards, multi-port test boards, etc. Although the Android system is more convenient to use and has a friendly interface, But its customization and functional scalability are not as good as traditional Linux systems. Traditional tablet computers only support the startup of a single system, that is, they only carry Android or Linux systems, and cannot take into account the advantages of both systems to provide developers and users with the convenience of applications. However, the existing embedded boards are either only equipped with a single operating system, or need to perform complex dual-system implantation operations to achieve dual-system startup. T...
