Problems solved by technology

[0002] Now more and more high-definition television (HDTV) set-top box solutions are using the LINUX system. Due to the large system characteristics, it takes a long time to upgrade the software; in the case of mass shipments of set-top boxes, function upgrades and bug fixes Finally, the software needs to be upgraded; when the software is upgraded, a sudden power failure will cause the set-top box (STB) to fail to start; if the software is upgraded in the startup boot program (U-BOOT), it will take a long time to wait and affect the user Unable to watch programs, causing inconvenience to users
[0003] At present, in the embedded system of general set-top boxes, data is restored in U-BOOT for program loss, and the data is obtained from the outside again. The operation is complicated, which is difficult for ordinary home users, and it takes a long time to restore data. time

Abstract

The invention discloses a method and a device for automatically restoring an embedded system of a set top box. The method comprises the steps of: carrying out power-on detection through a bootstrap loader so as to detect whether a first start system which is stored in a first program storage subarea and a second start system which is stored in a second program storage subarea are wrong or not; generating a first start system error flag and starting the second start system when detecting that the first start system which is stored in the first program storage subarea is wrong and the second start system which is stored in the second program storage subarea is correct; and automatically and completely copying the second start system which is stored in the second program storage subarea to the first program storage subarea to serve as a new first start system. In the invention, rapid restoration of system start of the set top box can be realized by using double systems, and automatic andrapid restoration can be realized without influencing the normal running time of the system, so that convenience is provided for users and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of set-top boxes, in particular to a method and device for automatically restoring an embedded system of a set-top box. Background technique [0002] Now more and more high-definition television (HDTV) set-top box solutions are using the LINUX system. Due to the large system characteristics, it takes a long time to upgrade the software; in the case of mass shipments of set-top boxes, function upgrades and bug fixes Finally, the software needs to be upgraded; when the software is upgraded, a sudden power failure will cause the set-top box (STB) to fail to start; if the software is upgraded in the startup boot program (U-BOOT), it will take a long time to wait and affect the user The program cannot be watched, causing inconvenience to the user. [0003] At present, in the embedded system of general set-top boxes, data is restored in U-BOOT for program loss, and the data is obtained from the outside again. The...
