mini2440新版移植.doc

Mini2440（128M）环境下面的操作环境见下表：目 录说 明OSRedhat 企业版 5交叉编译工具arm-linux-gcc 4.3.2Uboot获取u-boot.tgz，将其拷贝至虚拟机的工作目录下。编译步骤如下：rootlocalhost jj# tar xzvf u-boot.tgzrootlocalhost jj# cd u-boot-2010.03/rootlocalhost u-boot-2010.03# make distcleanrootlocalhost u-boot-2010.03# make smdk2440a_configConfiguring for smdk2440a board.rootlocalhost u-boot-2010.03# make烧写首先，安装开发板的USB驱动，并将USB接口线与主机相连。同时，使用串口线连接开发板与主机。将开发板的启动模式选择为nor，开发板上电后输出信息如下：# FriendlyARM BIOS 2.0 for 2440 #x format NAND FLASH for Linuxv Download vivi k Download linux kernel y Download root_yaffs image a Absolute User Applicationn Download Nboot for WinCE l Download WinCE boot-logow Download WinCE NK.bin d Download & Run z Download zImage into RAM g Boot linux from RAM f Format the nand flash b Boot the system s Set the boot parameters u Backup NAND Flash to HOST through USB(upload) r Restore NAND Flash from HOST through USB q Goto shell of vivi i Version: 0945-2KEnter your selection:键入“f”，完成nand flash的格式化。随后，键入“n”：Enter your selection: nUSB host is connected. Waiting a download.此时，开发板完成烧写uboot-bin文件的准备工作。在主机中打开“dnw”：顶部显示USB:OK，即表示usb驱动正常，可以实现文件下载。点击“USB Port”-“Transmit/Restore”，在弹出的对话框中，选择uboot的镜像文件“u-boot.bin”，点击“打开”后完成文件的烧写。此时，串口的输出信息如下：Enter your selection: nUSB host is connected.
