Method and device for simulating single-board software operating environment

Abstract

The invention relates to a method and a device for simulating an operating environment of single-plate software. The method comprises the following steps of: configuring a virtual hard disk, and correcting an address mapping mode in single-plate software codes; compiling a mapping file which is matched with a virtual machine arranged on a personal computer (PC); and operating the mapping file on the virtual machine, starting a virtual single plate, and mounting the virtual hard disk on the virtual single plate. In the invention, by configuring the virtual hard disk for storing solidification information, simulating access of a hardware address and compiling the mapping file which is matched with the virtual machine, simulation of the operating environment of the single-plate software on the PC is realized, so the single-plate software can operate normally without hardware. The invention has the advantages that: the early development and debugging of the single-plate software can be finished by a developer before the development of the single-plate hardware is finished; and physical network elements are simulated when network elements are not enough in a networking test, so a development period of the single plate is reduced, and development cost is reduced.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and device for simulating a single-board software operating environment. Background technique [0002] In the communication equipment system, the system equipment is composed of a single board or a board. The single board is mainly composed of CPU (Central Processing Unit, central processing unit), watchdog circuit and peripheral key processing chips. According to different functions, FPGA (Field-Programmable Gate Array, field programmable gate array) or DSP (Digital Signal Processing, digital signal processing) can be added. device) device. [0003] Usually, the hardware development cycle of a board is relatively long, and software developers need to wait for the development of the board to be completed before developing and debugging the board software. As a result, the development cycle and development cost of the single board are increased. [0004] Moreove...

Problems solved by technology

This increases the development cycle of the board and the development cost

[0004] Moreover, in the networking process, when the physical network elements are insufficient, the network test cannot be completed in time because the virtual single board cannot be run in the simulation environment to simulate the network elements.
