Embodiment approach

[0081] In this specific implementation manner, using the check code to determine whether the currently obtained merged file is correct is only a preferred implementation manner, and other implementation manners may also be used to determine the correctness of the merged file.

[0082] Introduced below figure 2 The specific implementation process of the preferred embodiment shown, such as image 3 shown, including:

[0083] Step 301, before merging the sub-files into one file according to the installation order of the sub-files, generate a check code for each sub-file according to a preset algorithm.

[0084] Step 302, during the process of merging sub-files into one file according to the installation order, each time a sub-file is merged, according to a preset algorithm, a check code A of the merged file d obtained after the current merging is completed is generated;

[0085] Step 303, calculating the sum B of the check codes of all sub-files that have been merged before be...

Abstract

The invention discloses a method and a device for burning a file into an EMMC (Embedded MultiMedia Card). The method comprises the following steps that: according to a model of user equipment, a system file corresponding to the model is obtained, and the system file comprises at least one sub file which is positioned in the same file folder; the installing sequence of the at least one sub file is determined according to the model of the user equipment, and the at least one sub file is merged into one file according to the installing sequence; and the merged file is converted into a set format and is burned into the EMMC corresponding to the user equipment. The method and the device have the advantages that a plurality of sub files can be merged into one file; the merged file is directly burned into the EMMC; and the defect that system sub files are installed into the EMMC only after the bare machine production completion of the user equipment is avoided, so the production efficiency of the user equipment is improved.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and device for burning files into an EMMC chip. Background technique [0002] At present, many mobile phone (a user equipment) manufacturers use EMMC (embedded MultiMedia Card, embedded multimedia chip) chip as the storage chip of the mobile phone, and the memory size of the chip determines the size of the mobile phone memory. The system of the mobile phone will be installed in the EMMC chip. At present, during the production process of the mobile phone, the method of installing the mobile phone system into the EMMC chip is as follows: [0003] Utilize the USB (Universal Serial Bus, Universal Serial Bus) data line to connect the bare metal of the mobile phone with the computer installed with the software platform corresponding to the model of the bare metal CPU of the mobile phone. After the bare metal production of the mobile phone is completed, use the software ...
