Example Embodiment

[0051] In order to describe in detail the technical content, structural features, achieved objectives and effects of the technical solution, the following detailed description will be given in conjunction with specific embodiments and accompanying drawings.

[0052] See figure 1 This embodiment provides an eMMC firmware upgrade method. This method can run in electronic equipment with eMMC. The electronic equipment should also include processing modules that can calculate and process, such as CPUs, and include , EMMC and other power supply modules. Users can use electronic devices to upgrade the firmware of eMMC. The upgrade specifically includes the following steps: first enter step S101 to obtain the firmware information of the eMMC. This firmware information can be part of the firmware information, file information (such as MD5 feature information, creation time, modification time, size, etc.), version information, etc., which can distinguish different firmware information. A...

Abstract

The invention discloses a firmware upgrade method and device for an eMMC. The firmware upgrade method can be applied to electronic equipment and includes the following steps of obtaining information of firmware of the eMMC, obtaining information of firmware to be upgraded from a server, comparing the information of the firmware to be upgraded with the information of the firmware of the eMMC, downloading the firmware to be upgraded from the server if the information of the firmware to be upgraded is inconsistent with the information of the firmware of the eMMC, and storing the firmware to be upgraded in a firmware storage area of the eMMC. By the adoption of the method, the firmware of the eMMC can be upgraded, and upgrade of firmware of an existing eMMC is achieved.

Description

technical field [0001] The invention relates to the field of stored data security, in particular to an eMMC firmware upgrade method and equipment thereof. Background technique [0002] eMMC (Embedded Multi Media Card) is an embedded memory standard specification established by the MMC Association, mainly for products such as mobile phones or tablet computers. It consists of an embedded storage solution with an MMC (Multimedia Card) interface, fast Flash memory (nand-flash) and eMMC controller. A clear advantage of eMMC is the integration of an eMMC controller in the package, which provides a standard interface and manages flash memory, allowing handset manufacturers to focus on other parts of product development and shorten the time to market. More and more mobile devices adopt eMMC as storage unit. [0003] Version 5.0 of the eMMC protocol starts to support firmware (Field firmware) upgrades, which requires additional support for eMMC firmware upgrades for operating syste...
