Abstract

The invention relates to electronic equipment, in particular to the initialization or configuration of a memory device in the electronic equipment. The invention provides the electronic equipment, which comprises a first initialization module, a second initialization module, a configuration file management module and a memory device detection module. The equipment has the advantages that a corresponding instruction can be automatically selected for initializing a memory according to the memory device concretely mounted on the equipment during the system initialization; the same series of equipment can be saved; and the problem that different versions of firmware need to be maintained during the mounting of different memory devices is solved.

Description

technical field [0001] The present invention relates to electronic equipment, and more particularly, the present invention relates to initialization or configuration of memory devices in electronic equipment. Background technique [0002] A storage device refers to a container that can accommodate certain transactions. Here it mainly refers to a memory device in a computer system, which is used to store programs and data. [0003] At present, the embedded linux operating system uses dtb (device tree blob) files to configure board-level resources. Device Tree is a data structure describing hardware, which originated from OpenFirmware (OF). After using DeviceTree, many hardware details can be directly passed to Linux through it, without the need for a lot of redundant coding in the kernel. Device tree information is recorded in the .dts file. DTC (device tree compiler) is a tool for compiling .dts files into .dtb files. refer to figure 1 , during the boot process, the fil...
