Embedded system construction method and storage medium

Abstract

The invention discloses an embedded system construction method and a storage medium, a disk is divided into four regions, and after a disk partition file system is mounted and detected, an automatic execution script file of a Ramdisk file system can also load a user-defined startup configuration script in a second disk partition for execution. When the user-defined startup script of the second partition is executed, a library file of the second partition is mounted under the library directory of the Ramdisk root file system, related configurations such as environment variables required by thesystem are added to execute the application program, and finally the application program of the third partition is loaded to execute. A user application program of the third partition performs read-write operation on the disk data in the fourth partition. According to the method, reliable operation of the system can be ensured, the system can automatically recover operation when started next timeeven under the condition that the system is illegally powered off, and dynamic configuration and flexibility of the whole system are greatly improved.

Description

technical field [0001] The invention relates to an embedded system, in particular to an embedded system construction method and a storage medium. Background technique [0002] The application scope of the embedded system is increasingly extensive, involving many aspects of human life, such as digital communication, information appliances, aerospace, industrial process control, engineering machinery control and military electronics. Embedded technology is becoming more and more closely related to all aspects of people's daily life, and the integration trend of consumer electronics, computers, and communications is becoming increasingly obvious, and it is an important part of the computer field. [0003] Embedded systems are application-centric, based on computer technology, and the software and hardware can be tailored, and are suitable for special systems that have strict constraints on function, reliability, cost, volume, and power consumption. [0004] Embedded systems ar...

Problems solved by technology

The existing conventional processing methods for embedded systems that use Emmc storage are: prohibiting forced power-off of embedded devices, such as mobile phone devices, the battery cannot be forcibly disassembled, and when the system battery is exhausted, a certain shutdown process , to deal with power failure; other embedded devices, the root file system may run directly on the disk, and all read and write operations will operate the disk, so in the case of illegal power failure, the possibility of disk damage is greatly increased In the case of disk damage, certain measures must be taken to repair or isolate the damaged disk
