Problems solved by technology

The upgrade process of the second upgrade method conforms to the specification, but if the upgrade fails, the terminal device will not be able to start normally and cannot continue to be used, and the software needs to be reprogrammed
[0006] To sum up, the OTA upgrade method in the prior art cannot simultaneously meet the requirement that the upgrade process conforms to the standard process, and still ensure the normal startup of the terminal device in the case of an upgrade failure.

Abstract

The invention discloses a system software updating method and a device in a terminal appliance. The method comprises that a first software partition of a terminal device is used as a main software partition, wherein the first software partition is indicated according to software partition information. A system software which is located in the first software partition can be initiated. When the initiated system software receives updating commands of the system software, a system software which is located in a second software partition can be updated according to a downloaded system software in a new edition, wherein the initiated system software is in an operational process. After the updating is completed, the main software partition which is indicated by the software partition information is modified from the first software partition to the second software partition. When the system software in the main software partition (such as the first software partition) is operated, the system software in a backup software partition (such as the second software partition) can be updated. Therefore, even though the updating is failed, the normal operation of the system software of the main software partition can be not affected. The terminal device can be guaranteed to initiate and operate normally as usual.

Description

technical field [0001] The invention relates to embedded system technology, in particular to a method and device for upgrading system software in terminal equipment. Background technique [0002] At present, embedded system software is widely used in the field of communication, industrial control, home smart devices, national defense, medical treatment and other fields. For example, mobile phones, smart TVs, set-top box terminal equipment, and handheld computers all use embedded systems to provide intelligent functions with better human-computer interaction performance. [0003] At present, the system software upgrade method based on OTA (Over-the-Air Technology, space download technology) is widely used in various terminal devices because of its convenience of upgrading; , such as WIFI, 3G, etc., automatically download the OTA upgrade package, and automatically upgrade the system software of the mobile phone or set-top box terminal equipment. [0004] At present, there ar...
