摘要:

为了实现嵌入式Linux操作系统在PXA270上的移植与应用,要求设计嵌入式引导程序。引导程序软件设计的重点和难点是内核和文件系统的下载与加载。文中通过网络传输实现下载功能,网卡芯片选用LAN91C111,设计了PXA270与该网卡芯片的硬件连接,数据接收与发送的软件流程,并借助网络数据监控软件对传输数据进行监控,保证了软件设计的正确性。详细分析了内核的加载过程与软件设计方法,实现了Linux操作系统的正常启动。该引导程序已成功运行于PXA270平台,可提供类似系统开发的直接借鉴

Abstract:

In order to realize the transplantation and application of the embedded Linux system on PXA270,bootloader is designed.The key of the bootloader software design is the download and loading of the kernel and file system.In this paper,the hardware PXA270 and the software programming of data-receiving and data-sending are designed based on LAN91C111 network card chip,which has fulfilled the download function of the file transmission with upper computer（VM Linux）.The software design is then examined as a real-time monitoring by using the data monitoring software.At last,the loading process of the kernel and the software design are described in detail which have started the Linux system successfully.The bootloader has aready succeeded in running on PXA270,which could be referenced directly in the other similar system
