Abstract

The invention discloses an EXT4 file system firmware upgrading method based on an eMMC. The upgrading method has the advantages that through network upgrading, it is guaranteed that the network of equipment is always communicated with the outside world before upgrading and in the upgrading process, and other equipment can obtain a real-time state through the network; the eMMC can be upgraded simply, conveniently and quickly like JFFS, SQUAFS or ROMFS in NOR FLASH; normal upgrading of the eMMC can be guaranteed, the state can be obtained through the network, upgrading convenience is improved, needed manpower and material resources are reduced, the upgrading condition of each device can be conveniently known through the network, and upgrading of a single partition, multiple partitions and the whole FLASH partition of the device end is supported.

Description

technical field

[0001] The invention relates to eMMC computer technology, in particular to an eMMC-based EXT4 file system firmware upgrading method. 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. eMMC integrates a controller in the package, provides a standard interface and manages the flash memory, allowing related device manufacturers to focus on other parts of product development and shorten the time to market.

[0003] Different from SPI NOR FLASH, the commonly used jffs2 or squafs file system, this file system is the kernel decompresses the root system to the memory and then runs (in short, these file systems have nothing to do with flash when running), so this The system can directly burn flash to upgrade, but ext4 based on eMMC is different from them. In layman’s terms, ext4 is a flash-related file system. If ...

Embodiment Construction

[0028] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0029] refer to figure 1 , the present invention provides a method for upgrading the firmware of the EXT4 file system based on eMMC, comprising steps:

[0030] S1. The terminal device receives the eMMC firmware package information from the host through the network protocol;

[0031] As a preferred embodiment of the present invention, network protocols such as UDP / TCP are used in step S1. The firmware package information includes information about the hardware platform, hardware version, software version, and SDK version of the device to which the firmware is adapted.

[0032] S2. After the terminal device receives the eMMC firmware package information transmitted by the host for upgrading, the terminal device judges whether it meets the upgr...
