Embodiment 1

[0065] Such as figure 1 As shown, the present invention provides a kind of flash memory data management method, and this method comprises the following steps:

[0066] S101. Set the root file system of the wireless communication module as a read-only file system, and mount it to the memory file system;

[0067] Mounting the root file system to the memory file system ensures the reliability of the root file system. When the user performs temporary read and write operations on the root file system, the content is actually written to the memory file system, and the root file system has not been changed. After the system restarts, the temporary files of the memory file system disappear without affecting the system. start up.

[0068] S102. Set the root file system as a composite file system, and mount the configuration directory of the root file system to the readable and writable file system partition of the flash memory in the wireless communication module.

[0069] Wherein, ...

Embodiment 2

[0102] Such as Image 6 As shown, the hardware structure of a wireless communication device provided by the embodiment of the present invention uses a flash memory (NAND Flash) as a data storage medium. Specifically, the wireless communication device 40 includes at least a processor 41 and a flash memory 42 and data bus 43 . The data bus 43 is used to realize the connection and communication between the processor 41 and the flash memory 42. The flash memory 42, as a computer-readable storage medium, can store at least one computer program, which can be read and compiled by the processor 41. And execute, so as to realize the corresponding processing flow. In this embodiment, the flash memory 42 is used as a computer-readable storage medium, in which a flash data management program is stored, and the program can be executed by the processor 41, so as to implement the following steps of the flash data management method:

[0103] Mount the root file system of the wireless commun...

Abstract

The invention discloses a flash memory data management method and device and a computer readable storage medium, and relates to the technical field of data storage management. The flash memory data management method and device and the computer readable storage medium aims at solving the technical problem of an existing wireless communication device that the module stability and reliability are influenced since flash memory data is abnormal. The flash memory data management method comprises the following steps of setting a root file system of a wireless communication module as a read-only file system and mounting a laminated file system to a memory; setting the root file system as the laminated file system and mounting a configuration catalogue of the root file system into a readable and writable file system partition of a flash memory in the wireless communication module. According to the flash memory data management method and device and the computer readable storage medium, the laminated file system and a recovery mechanism of the file system are adopted to improve the stability and reliability of the wireless communication module, and after-sales maintenance work of a product of the type of the wireless communication module is also reduced.

Description

technical field [0001] The present invention relates to the technical field of data storage management, in particular to a flash memory data management method, device and computer-readable storage medium. Background technique [0002] Nand-flash memory is a kind of flash memory. In 1989, Toshiba Corporation published the NAND flash structure. It uses a non-linear macro-cell mode inside, which provides a cheap and effective solution for the realization of solid-state large-capacity memory. Nand-flash memory has the advantages of large capacity and fast rewriting speed, and is suitable for the storage of large amounts of data, so it has been more and more widely used in the industry. For example, embedded products include digital cameras, MP3 walkman memory cards, volume Small U disk, etc. [0003] For example, wireless communication devices that store data through Nand-flash memory are widely used in fields such as industrial control, security, smart city management, wirele...
