Abstract

A systematic one-key reset device applicable to an embedded Linux operating system belongs to the technical field of embedded systems. An embedded Linux operating on an ARM11 chip serves as a carrier. The systematic one-key reset device comprises a direct-current power supply module, a switch control module, a main processor module, a main processor start control module, a main processor reset module, a coprocessor module, a secure digital (SD) card module and a Nand Flash module. The systematic one-key reset device is characterized in that the direct-current power supply module supplies power to a whole system, and the switch control module is connected with the coprocessor module which is respectively connected with the main processor start control module and the main processor reset module through general input-output (IO) ports. The systematic one-key reset device adopts modular structures, is simple in hardware interface, convenient to debug and install, and is used on movable terminals. The systematic one-key reset device is short in development cycle, strong in practical applicability, applicable to one-key reset based on an embedded Linux operating system platform, and obvious in advantages on developing difficulty, working capacity and cost.

Description

technical field [0001] The invention relates to a hardware realization of a system one-key restore device suitable for an embedded Linux operating system, and belongs to the technical field of embedded systems. Background technique [0002] With the continuous development of information technology, many handheld devices have become popular Internet access devices because of their low power consumption and portability. Therefore, embedded operating systems applied to various handheld devices have gradually come into the public's field of vision. Linux is an operating system with a UNIX-like kernel that supports multi-users, multi-tasking, multi-threading, and multi-CPU with the network as the core. It is currently one of the most dynamic operating systems. In terms of stability and reliability, it has the characteristics of a server operating system. It is often used to build various server platforms and has a high cost performance. In addition, the Linux system has a great ...
