PowerPC平台 Linux移植二
来源：互联网 发布：橡塑保温板 淘宝 编辑：程序博客网 时间：2024/05/21 07:14
继PowerPC平台 Linux移植一，制作busybox文件系统，目的实现单板挂载nfs文件系统。
1.制作busybox文件系统
（1）交叉编译busybox
a.make menuconfig
配置Cross Compile prefix 位powerpc-linux-gnu-
Installation Options 路径指定为/home/freescale/work/source/fs_mini
b.make
DOC busybox.pod
DOC BusyBox.txt
DOC BusyBox.1
DOC BusyBox.html
freescale@freescale-sdk:~/work/source/busybox-1.1
c.安装
freescale@freescale-sdk:~/work/source/busybox-1.13.3$ make install
..........
/home/freescale/work/source/fs_mini/usr/sbin/telnetd -> ../../bin/busybox
/home/freescale/work/source/fs_mini/usr/sbin/udhcpd -> ../../bin/busybox
--------------------------------------------------
You will probably need to make your busybox binary
setuid root to ensure all configured applets will
work properly.
--------------------------------------------------
freescale@freescale-sdk:~/work/source/busybox-1.13.3$
（2）安装glibc库
freescale@freescale-sdk:~/work/source/busybox-1.13.3$ cd ..
freescale@freescale-sdk:~/work/source$ mkdir fs_mini/lib
freescale@freescale-sdk:~/work/source$ echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/home/freescale/work/tools/freescale-2010.09/bin
freescale@freescale-sdk:~/work/source$ cp /home/freescale/work/tools/freescale-2010.09/powerpc-linux-gnu/libc/te500v2/lib/*so* /home/freescale/work/source/fs_mini/lib -d
freescale@freescale-sdk:~/work/source$ mkdir fs_mini/usr/lib -p
freescale@freescale-sdk:~/work/source$ cp /home/freescale/work/tools/freescale-2010.09/powerpc-linux-gnu/libc/te500v2/usr/lib/*so* /home/freescale/work/source/fs_mini/usr/lib -d
freescale@freescale-sdk:~/work/source$
（3）构建etc目录
freescale@freescale-sdk:~/work/source/nfs_root/rootfs_dir$ mkdir etc
freescale@freescale-sdk:~/work/source/nfs_root/rootfs_dir$ vim etc/inittab
console::askfirst:-/bin/sh
::sysinit:/etc/init.d/rcS
保存退出
freescale@freescale-sdk:~/work/source/nfs_root/rootfs_dir$ vim etc/init.d/rcS
#!/bin/sh
ifconfig eth0 172.16.1.111
mount-a
freescale@freescale-sdk:~/work/source/nfs_root/rootfs_dir$ chmod +x etc/init.d/rcS
freescale@freescale-sdk:~/work/source/nfs_root/rootfs_dir$ vim etc/fstab
proc /proc proc defaults 0 0
（4）构建dev目录
freescale@freescale-sdk:~/work/source/fs_mini$ ls -l /dev/console /dev/null
crw------- 1 root root 5, 1 2015-05-18 14:28 /dev/console
crw-rw-rw- 1 root root 1, 3 2015-05-18 14:28 /dev/null
freescale@freescale-sdk:~/work/source/fs_mini$ sudo mknod dev/console c 5 1
freescale@freescale-sdk:~/work/source/fs_mini$ sudo mknod dev/null c 1 3
（5）创建其他目录
freescale@freescale-sdk:~/work/source/fs_mini$ mkdir proc tmp mnt sys root
freescale@freescale-sdk:~/work/source/fs_mini$
2.制作文件系统镜像文件
安装genext2fs，参考install文档，安装如下：
To install, just do it the normal GNU way:
./configure
make
make install
freescale@freescale-sdk:~/work/tools/genext2fs-1.4.1$ sudo make instal
freescale@freescale-sdk:~/work/source$ genext2fs -b 4096 -d fs_mini fs_mini_ramdisk
genext2fs: couldn't allocate a block (no free space)
freescale@freescale-sdk:~/work/source$ genext2fs -b 8192 -d fs_mini fs_mini_ramdisk
genext2fs: couldn't allocate a block (no free space)
这个错误的原因是给的大小太小了，需要把大小增大，查看手册只是说了 “size of the image in blocks”，
这样 于是便先使用 du -h rootfs，计算出来
freescale@freescale-sdk:~/work/source$ du -h fs_mini
1.9M fs_mini/bin
4.5M fs_mini/lib
4.0K fs_mini/tmp
4.0K fs_mini/sys
4.0K fs_mini/mnt
4.0K fs_mini/usr/bin
1.7M fs_mini/usr/lib
4.0K fs_mini/usr/sbin
1.7M fs_mini/usr
4.0K fs_mini/root
4.0K fs_mini/dev
4.0K fs_mini/sbin
4.0K fs_mini/proc
8.0M fs_mini
freescale@freescale-sdk:~/work/source$ genext2fs -b 10240 -d fs_mini fs_mini_ramdisk
freescale@freescale-sdk:~/work/source$
3.修改p1010rdb.dtb 配置文件
p1010rdb.dtb 配置文件，用于linux传参数
/home/freescale/work/source/linux-2.6.35-r2/arch/powerpc/boot/dts/p1010rdb.dts
/home/freescale/work/source/linux-2.6.35-r2/scripts/dtc/dtc

4.解决死机问题：
(1)配置kernel
CONFIG_DEVTMPFS=y
CONFIG_DEVTMPFS_MOUNT=y
重新编译kernel
(2)修改p1010rdb.dts
去掉nand 配置部分
根据报错去掉串口1、I2C，系统打印一大堆udevd[1170]: unable to receive ctrl connection: Function not implemented
跑起来了
p1010 login: root
root@p1010:~# cd /
root@p1010:/# ls
bin etc linuxrc mnt sbin usr
boot home lost+found proc sys var
dev lib media run tmp
5.配置phy,编译p1010rdb.dts文件
配置phy地址phy:6 phy2:4
phy0: ethernet-phy@0 {
interrupt-parent = <&mpic>;
interrupts = <3 1>;
reg = <0x1>;
};
phy1: ethernet-phy@1 {

reg = <0x6>;
};
phy2: ethernet-phy@2 {

};
编译p1010rdb.dts
