基于QEMU的嵌入式系统仿真环境的构建

摘要

Take the open source instruction-level simulator QEMU as the hardware simulation platform. And simulate the development board named MINI2440 who is the representative of the ARM9 embedded platform. It's easily to used with different OS porting experiment under the situation of no hardware in ARM. Firstly,QEMU simulator was used to simulate the S3C2440 embedded environment. And then realize the embedded simulation system who takes U-Boot as the boot loader,ARM-LINUX as the kernel,and rootfs_qtopia_qt4 as the file system. We can also research and develop the QT4 application in this graphics system. This emulation environment provided an effective and inexpensive study and development platform for the embedded software developer.%以QEMU开源指令级仿真软件作为硬件仿真平台,对以MINI2440开发板为代表的ARM9嵌入式平台进行模拟仿真,实现在没有ARM硬件的情况下进行各种系统移植实验和基于该嵌入式系统环境的应用程序开发.首先使用QEMU仿真软件对S3C2440嵌入式环境进行仿真,然后移植实现了以U-Boot为引导程序、ARM-LINUX为内核、rootfs_qtopia_qt4为文件系统的嵌入式仿真系统.在该系统图形环境中,可以进行基于QT4的应用程序研究开发.该仿真环境的构建,为嵌入式软件开发者提供了高效且廉价的学习开发平台.
