Embodiment
[0036] This embodiment provides a method for upgrading the operating system across partitions on 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 corresponding partition addresses of each file in the new version of the operating system software in the memory. The partition address may be the partition where the file is located, or further the location in the partition where the file is located, or 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 partition address is not limited to a specific memory address, but can also be the size of the space occupied by the partition or other, as long as repartitioning can be achieved...

The invention provides a method and system for updating an operating system of T cards in a trans-partition mode. The method includes the steps new version operating system software is read; the new version operating system software comprises a first partition table; initial addresses of all partitions in the first partition table are sought; old version operating system software is read; the old version operating system software comprises a second partition table; initial addresses of all partitions in the second partition table are sought; the initial addresses of all the partitions in the first partition table are used as initial addresses of all the updated partitions, and mirror images of files of all the partitions in the new version operating system software are written to the addresses of the partitions after being updated. According to the method and system, under the condition that the partitions of the system change, an old version operating system can be directly updated, and the problem that with a traditional operating system updating method, trans-partition updating can not be achieved is solved.
Description
Technical field [0001] The invention belongs to the field of computer technology, and relates to an operating system upgrade method, in particular to a method and system for upgrading an operating system across partitions by 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 days and later by the Open Handheld Device Alliance. With the development of electronic technology, the version of Android is constantly updated and the functions are constantly improved. In order to enable obsolete mobile terminals to meet the needs of users, it is necessary to upgrade 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 that follow. At the same time, with the version update of the Android system, in order to sol...
