搭建mips平台编译环境及生成相关

一、搭建mips平台编译环境及生成相关
准备工作
1、在home目录下建立一个mute目录，用于项目开发相关开发的一个目录
2、 拷贝西格码公司提供的SMP8634平台相关开发源码包到刚才新建的目录mute下。
第一步：建立编译环境
1、在mute目录下解压 smp86xx_toolchain_2.8.0.1.tar.bz2 包
debian:/home/mute# tar jxvf smp86xx_toolchain_2.8.0.1.tar.bz2
2、进入解压后的目录
debian:/home/mute# cd smp86xx_toolchain_2.8.0.1
3、拷贝以下源码包到dl目录下（说明：）
binutils-2.15.91.0.2.tar.bz2  gcc-3.4.2.tar.bz2  linux-libc-headers-2.6.11.0.tar.bz2
ccache-2.3.tar.gz             gdb-6.5.tar.bz2    uClibc-0.9.27.tar.bz2
debian:/home/mute/smp86xx_toolchain_2.8.0.1# cp -ar /8634/smp86xx_toolchain_2.8.0.1/dl/* ./dl/
4、配置交叉工具链
debian:/home/mute/smp86xx_toolchain_2.8.0.1# make menuconfig

5、编译
debian:/home/mute/smp86xx_toolchain_2.8.0.1# make
debian:/home/mute/smp86xx_toolchain_2.8.0.1# source toolchain-path.env
第二步：编译bootloader
1、
debian:/home/mute#tar zxvf CPU_KEYS_SMP8634_xosMc0-1.tar.gz
debian:/home/mute# cd CPU_KEYS_SMP8634_xosMc0-1
debian:/home/mute/CPU_KEYS_SMP8634_xosMc0-1# source CPU_KEYS.env
debian:/home/mute# tar jxvf smp86xx_boot_loader_2.8.0.1.tar.bz2
debian:/home/mute# cd smp86xx_boot_loader_2.8.0.1
debian:/home/mute/smp86xx_boot_loader_2.8.0.1# ls
Makefile  README  inc.gnxnv.Makefile  inc.yamon.Makefile  inc.zboot.Makefile  pf  tools  zboot
debian:/home/mute/smp86xx_boot_loader_2.8.0.1# ln -s tools/genxenv/configs/852-E2.config  xenv.config

debian:/home/mute/smp86xx_boot_loader_2.8.0.1# ls /8634/smp86xx_boot_loader_2.8.0.1/reference/
eBIOS_v1.5_LED  eBIOS_v1.5_LED.tar.gz
debian:/home/mute/smp86xx_boot_loader_2.8.0.1# mkdir reference
debian:/home/mute/smp86xx_boot_loader_2.8.0.1# cp /8634/smp86xx_boot_loader_2.8.0.1/reference/eBIOS_v1.5_LED.tar.gz  reference/

debian:/home/mute/smp86xx_boot_loader_2.8.0.1# make yamon

debian:/home/mute/smp86xx_boot_loader_2.8.0.1# cp bin/* /tftpboot/mute/

第三步：建立文件系统
debian:/home/mute# tar jxvf smp86xx_rootfs_2.8.0.1.tar.bz2
debian:/home/mute# cd smp86xx_rootfs_2.8.0.1
debian:/home/mute/smp86xx_rootfs_2.8.0.1# ls
Config.in  Makefile  README  package  target  test_if_zlib_is_available.sh  toolchain  tools  xbin
debian:/home/mute/smp86xx_rootfs_2.8.0.1# mkdir dl
debian:/home/mute/smp86xx_rootfs_2.8.0.1# ls
Config.in  Makefile  README  dl  package  target  test_if_zlib_is_available.sh  toolchain  tools  xbin
debian:/home/mute/smp86xx_rootfs_2.8.0.1# cp /8634/smp86xx_rootfs_2.8.0.1/dl/* ./dl/
debian:/home/mute/smp86xx_rootfs_2.8.0.1# ls dl
bash-3.0.tar.gz        cramfs-1.1.tar.gz  linux-libc-headers-2.6.11.0.tar.bz2  uClibc-0.9.27.tar.bz2
busybox-1.5.0.tar.bz2  gdb-6.5.tar.bz2    ncurses-5.2.tar.gz
debian:/home/mute/smp86xx_rootfs_2.8.0.1# make menuconfig
Package Selection for the target  --->
