Embodiment Construction

[0026] refer to figure 1 , the present invention includes for the generation method embodiment of NAND Flash burning file:

[0027] 101. Obtain a partition description file and its corresponding configuration information and user data;

[0028] When it is necessary to generate a NAND Flash burning file, obtain the partition description file and its corresponding configuration information and user data. The partition description file includes the partition description information of one or more partitions, and the configuration information includes the generated number of burning files. User data is the main data to be burned;

[0029] Among them, the partition description file and corresponding configuration information and user data can be stored locally in advance, or can be obtained by user input, and there is no limitation here;

[0030] 102. Determine the file format to which the corresponding partition file belongs according to the partition description file;

[0031]...

Abstract

The embodiment of the invention discloses a NAND Flash writing file-orientated generating method and a corresponding device, as well as a generation device corresponding to the method. The method comprises the following steps: obtaining a partition description file including partition description information, as well as configuration information and user data corresponding to the file; judging the format of the partition file according to the partition description file; and generating the writing file according to the partition description information and the corresponding number of the writing file to be generated. Due to the adoption of the method provided by the invention, files of different formats can be identified to automatically generate the writing files, so that the practicability is strong, the flexibility is high, and efficiency of writing the writing file into a NAND Flash is greatly improved.

Description

technical field [0001] The invention relates to the field of computer data storage, in particular to a method for generating a NAND Flash programming file and a corresponding device. Background technique [0002] Non-volatile flash memory (NAND Flash) is more and more widely used as a carrier for storing data in the embedded field due to its large capacity, fast access speed and low cost per unit capacity. [0003] Currently, there are two main file formats of NAND Flash: Memory Technology Device (MTD, Memory Technology Device) and Unsorted Block Images (UBI, Unsorted Block Images). Among them, UBI is an open source NAND management software, which can effectively improve the reliability and product life of using NAND. UBI will add its own management information to the head of each user data. Among them, user data is an independent bin file organized in the form of partitions. The partition size is aligned with the size of the storage block when setting. The partitions of ea...
