Problems solved by technology

Therefore, it is very important to identify the version information in the firmware. In the existing technical solutions, it is necessary to designate a special area in the firmware for saving the firmware version. This solution increases the file size of the firmware file virtually; in addition, When using a remote method such as the network to update the firmware, the existing technical solution needs to download the firmware first, and then obtain the version information from the firmware, and the downloaded firmware version may be older than the current one, resulting in a redundant download

Embodiment Construction

[0032] The present invention provides a firmware version update method and system. In order to make the object, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0033] Such as figure 1 A method for updating a firmware version is shown, wherein the method includes the following steps:

[0034] S100. The mobile terminal detects new firmware in the memory card or detects new firmware information on the server through the network, and acquires file size information of the new firmware.

[0035] There are generally two ways for the mobile terminal to detect the newly added firmware information. One of them is that the mobile terminal detects whether the file type of the file in the memory card has a firmware file type, and if it exists, o...

Abstract

The invention discloses a firmware version updating method and system. The firmware version updating method comprises the steps that A, when a mobile terminal detects that newly-added firmware exists in a memory card or information of the newly-added firmware on a server is detected through a network, the information of the file size of the newly-added firmware is obtained; B, the obtained information of the file size of the newly-added firmware is compared with the information of the file size of current firmware which is stored in advance, judgment is conducted, and if the file size of the newly-added firmware is larger than that of the current firmware, the step C is executed; C, the firmware is updated with the newly-added firmware. According to the firmware version updating method and system, due to the fact that the correspondence relation between the firmware version and the file size of the firmware is set, the purpose that the firm version can be identified just according to the file size of the firmware in the process of updating the firmware is achieved, the problem that due to the fact that version information is stored, the file is increased or the newest firmware version cannot be obtained remotely is solved, and timely updating of the firmware is facilitated.

Description

technical field [0001] The invention relates to firmware update technology, in particular to a firmware version update method and system. Background technique [0002] The mobile terminal often needs to update the firmware, and before the update, the version of the firmware needs to be obtained first, and compared with the firmware version in use, if the version of the firmware is newer than the version of the firmware in use, the firmware will be updated, otherwise the firmware will not be updated. Therefore, it is very important to identify the version information in the firmware. In the existing technical solutions, it is necessary to designate a special area in the firmware for saving the firmware version. This solution increases the file size of the firmware file virtually; in addition, When using a remote method such as the network to update the firmware, the existing technical solution needs to download the firmware first, and then obtain the version information from ...
