Problems solved by technology

However, Linux embedded systems generally do not have physical hard disk devices. One technology is to store data in flash memory (flash) block devices, which seems to solve this problem, but flash block devices must be erased before writing, and erase The number of divisions is relatively limited, so this method becomes not completely reliable, and it is difficult to meet the reliability requirements of telecom-grade equipment

Abstract

The embodiment of the invention discloses an operation method of a non-volatile RAM, a data operation method and a relevant device. The operation method of the non-volatile RAM comprises the following steps: a block device file corresponding to a non-volatile RAM area is generated; the block device file is formatted so as to enable the formatted block device file to support a first file system; the formatted block device file is mounted under the catalog of the first file system. The technical scheme provided by the embodiment of the invention facilitates the realization of no loss of data after the system is subjected to warm start or abnormal reset on the premise of being safe and reliable as far as possible.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method for operating nonvolatile memory, a method for data operation and related devices. Background technique [0002] In the personal computer system, data storage is an extremely important and necessary function, and the data will not be lost after the system is abnormally reset, which is convenient for the subsequent positioning of the problem. At present, personal computers store data on physical hard disks. [0003] With the widespread application of Linux embedded systems in telecommunication equipment, it is also required to store the Linux system data and ensure that the data will not be lost after the system is hot-started or abnormally reset. However, Linux embedded systems generally do not have physical hard disk devices. One technology is to store data in flash memory (flash) block devices, which seems to solve this problem, but flash block devices must be erase...
