Embodiment

[0036] This embodiment provides a method for upgrading the operating system across partitions of a T card, such as figure 1 As shown, the method for upgrading the operating system across partitions of the T card includes:

[0037] Read the new version of the operating system software. The new version of the operating system software includes a first partition table; the first partition table indicates the partition address correspondingly written in the memory for each file in the new version of the operating system software. The partition address may be the partition where the file is located, or further be the location in the partition where the file is located, or further be the address of the space occupied by the partition where the file is located in the memory and the writing address of the file. It can be said that the address of the partition is not limited to a specific memory address, it can also be the size of the space occupied by the partition or other, as long ...

Abstract

The present invention provides a method and system for upgrading an operating system across partitions of a T card. The method includes: reading the new version of the operating system software; the new version of the operating system software includes a first partition table; start address; read the old version operating system software in the memory; include the second partition table in the old version operating system software; find the start address of each partition in the second partition table; set the start address of each partition in the first partition table The starting address is used as the starting address of each partition after the upgrade, and the file images of each partition of the new version of the operating system software are written into the partition addresses after the upgrade. The invention can directly upgrade the old version of the operating system when the system partition changes, and solves the problem that the traditional operating system upgrading method cannot be upgraded across regions.

Description

technical field [0001] The invention belongs to the technical field of computers and relates to an operating system upgrading method, in particular to a method and a system for upgrading an operating system across partitions of a T card. Background technique [0002] Android is an operating system based on the Linux kernel. It is a mobile phone operating system announced by Google on November 5, 2007. It was developed by Google in the early stage and later developed by the Open Handheld Devices Alliance. With the development of electronic technology, the version of Android is constantly updated and its functions are constantly improved. In order to make the obsolete mobile terminals meet the needs of users, it is necessary to upgrade the obsolete mobile terminals. [0003] With the development of mobile terminal software, its functions are becoming more and more complex, and there are more and more defects. At the same time, with the version update of the Android system, in...
