Embodiment Construction

[0034] The present invention will be further described below with reference to the accompanying drawings and in combination with preferred embodiments.

[0035] The Android system has its own Recovery system, which is used to complete system upgrades, recovery and other functions. However, the existing Android system’s built-in Recovery and the Android system share the same root file system. When the root file system image on the storage device is damaged , unable to enter the Recovery system for recovery. Strictly speaking, Android Recovery cannot be completely separated from the main Android system, and it is not a real dual system. For this, as figure 1As shown, the present invention improves the embedded system of the smart set-top box based on Android, and adopts the dual system framework of the auxiliary Android system 300 (hereinafter referred to as the Android small system) and the main Android system 200 (hereinafter referred to as the Android large system), and the ...

Abstract

The invention discloses an embedded system of an intelligent set top box based on the Android and a recovery method of the embedded system. The system comprises a guide system and a main Android system used for providing functions required by application of a user. The system is characterized in that the system further comprises an auxiliary Android system, the auxiliary Android system and the main Android system share a kernel, a root file system of the auxiliary Android system and a root file system of the main Android system are mutually independent and are stored in different physical regions in a storage device of the intelligent set top box; the auxiliary Android system comprises a recovery unit used for conducting system recovery on the main Android system; the guide system comprises a counter, a switching module and a guide module and used for starting the auxiliary Android system to conduct recovery on the main Android system when the number of start failure of the main Android system reaches the rated number. The embedded system of the intelligent set top box based on The Android has the advantages of being stable in operation and reliable in recovery function.

Description

technical field [0001] The invention relates to an embedded system, in particular to an embedded system of an Android-based intelligent set-top box and a recovery method thereof. Background technique [0002] The Android (Android) system is an open source mobile phone operating system based on the Linux kernel announced by Google in November 2007. It is a set of mobile software developed for mobile terminals. Google established a global alliance organization composed of many mobile phone manufacturers, telecom operators, and chip manufacturers to jointly develop the Android system. Since then, the Android system has been continuously upgraded and its functions have become more and more perfect. At present, Samsung, HTC, and Motorola have all launched their own Android phones, and Google has also launched Google TV based on the Android system, coupled with Hong Kong Huafeng's e-way M7 navigator, and MIPS' high-definition set-top box, all of which make the Android system big. ...
