Embodiment Construction
[0042] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0043] The system of the terminal device includes a running system and an expansion system. The terminal device includes non-volatile storage space and memory. The non-volatile storage space may include FLASH storage media, such as NOR storage media, NAND storage media, EMMC storage media, etc. Among them, the non-volatile storage space has a system partition and an extended partition, the system partition is used to store the running system, and the extended ...

The invention relates to an upgrading method of a system of terminal equipment. The system of the terminal equipment comprises an operating system and an extension system; a nonvolatile memory space of the terminal equipment is provided with a system sub-region and an extension sub-region; the system sub-region is used for storing the operating system; and the extension sub-region is used for storing the extension system. The upgrading method of the system of the terminal equipment comprises the following steps: acquiring a file of a recovery system and burning the recovery system to the extension sub-region; acquiring an upgrading file of the operating system and recording the upgrading file to the system sub-region to upgrade the operating system; if the upgrading of the operating system fails, starting the system through the recovery system burnt by the extension sub-region; obtaining the upgrading file of the operating system again and burning the upgrading file to the system sub-region; and if the operating system is upgraded successfully, downloading the upgrading file of the extension sub-region and burning the upgrading file to the extension sub-region. According to the upgrading method of the system of the terminal equipment, the terminal equipment with a relatively small nonvolatile memory space is stably upgraded, the storage space is saved, and the product cost is reduced.
Description
technical field [0001] The invention relates to the field of software, in particular to a method for upgrading a terminal equipment system. Background technique [0002] With the development of science and technology, OTA (Over the Air Technology) is widely used in various terminal equipment products, which improves the convenience of terminal equipment. OTA is a technology for remote management of SIM card data and applications through the air interface of mobile communication. Among them, the air interface can use WAP, GPRS, CDMA1X, short message and other technologies. [0003] At present, the upgrade of terminal equipment mainly adopts the following methods: [0004] Part of the physical space is divided in the non-volatile storage space of the terminal equipment product to store and restore the system. When the system is upgraded, the terminal device product downloads the upgrade file through OTA technology and upgrades. If the system upgrade fails, the system can be ...
