第19章移植2內核和根文件系統(tǒng)

北風網項目實戰(zhàn)培訓第19章：系統(tǒng)移植2：內核和根文件系統(tǒng)移植講師：老夫子（北風網)基于QT的PMP媒體播放器內核移植根文件系統(tǒng)移植NFS設置本講大綱一、解壓tar-xvflinux--mini2440-20100921.tar.gz二、設置交叉編譯工具cdlinux-exportPATH=/usr/local/arm/4.3.2/bin:$PATH三、編譯cpconfig_mini2440_x35.configmakemenuconfigmakezImage

內核移植步驟1四、制作uImage../../uboot/tekkamanninja-u-boot-2010.03-tekkaman-052d395/tools/mkimage-n'linux-2.6.32'-Aarm-Olinux-Tkernel-Cnone-a0x30008000-e0x30008040-darch/arm/boot/zImagearch/arm/boot/uImage.img五、通過UBoot下載內核tftp0x30008000uImage.imgnanderase0x80000300000nandwrite0x300080000x80000300000setbootcmd'nandread0x300080000x80000300000;bootm0x30008000'saveenvreset內核移植步驟2一、解壓打包工具tarxvzfmkyaffs2image.tgz-C/二、創(chuàng)建文件系統(tǒng)mkdir/root/rootfscd/root/rootfsmkdirbindevetcusrlibsbinprocmkdirusr/binusr/sbinusr/lib三、解壓busyboxcd/root/yizhi/rootfstar-xvfbusybox-1.13.3-mini2440.tgzcdbusybox-1.13.3根文件系統(tǒng)移植步驟1四、配置busyboxmakemenuconfigBusyboxsetting ->buildsoptions ->[*]buildbusyboxasastaticbinary（a） ->installitationoptions ->[*]don’tuse/usr（b）根文件系統(tǒng)移植步驟2五、編譯makeARCH=armPILE=arm-linux-CONFIG_PREFIX=/root/rootfsallinstall六、制作配置文件cd/root/rootfs/etcviprofile內容如下#!/bin/shecho"Setseaechlibraryin/etc/profile"exportLD_LIBRARY_PATH=/libecho"Setuserpathin/etc/profile"exportPATH=/bin:/sbin:/usr/bin根文件系統(tǒng)移植步驟3七、創(chuàng)建設備文件cd/root/rootfsmknoddev/consolec51mknoddev/nullc13mknoddev/tty1c41mknoddev/tty2c42mknoddev/tty3c43mknoddev/tty4c44

八、拷背庫文件cp/usr/local/arm/4.3.2/arm-none-linux-gnueabi/libc/armv4t/lib/*-a/root/rootfs/lib/九、壓制文件系統(tǒng)cd/root/mkyaffs2image-128Mrootfsrootfs.yaffs2根文件系統(tǒng)移植步驟4十、設置flash啟動setbootargs'noinitrdroot=/dev/mtdblock3rootfstype=yaffs2rwconsole=ttySAC0,115200init=/linuxrcmem=64M'Saveenvreset十一、設置NFS啟動setenvbootargsroot=/dev/nfsnfsroot=1:/root/rootfsip=init=/linu
