Embodiment Construction

[0044] The core of the present invention is to provide a booting method, device, equipment and a computer-readable storage medium of a Linux system, which effectively solves the problem that the Linux system cannot be started normally due to the inability to correct multiple errors in a single Page of an image file.

[0045] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Abstract

The invention discloses a starting method of a Linux system. A backup image area file is set for the image area file of the Linux system in advance. After the request to start the Linux system is received, the main image area file is read first, and whether it is correct or not is judged. If not, the backup image area file is loaded to start the Linux system. According to the method, through the preset backup, when the mirror area file makes an error, the system can be started by loading the backup to avoid the situation that the system cannot be started because multiple errors occur in a single page of a mirror file cannot be corrected. In addition, the invention also provides a boot device and equipment of a Linux system, and a computer-readable storage medium the function of which corresponds to the function of the method.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a method, device, equipment and a computer-readable storage medium for starting a Linux system. Background technique [0002] At present, most embedded Linux systems store system image files in NandFlash, but due to the intrinsic characteristics of NandFlash's own hardware, it will occasionally cause bit inversion. The occurrence of bit inversion will cause damage to the system image file, which cannot be consistent with the original target file, thus causing the system to fail to start normally. Therefore, there is an urgent need for a method to solve the problem that the system cannot be started due to bit inversion in NandFlash. [0003] The current solution to this problem is mainly to check whether the file is abnormal by performing ECC verification on the entire page of NandFlash data, and make corresponding corrections. ECC, the full name is Error Checking and Correction...
