util-linux/umount.c: In function `umount_main‘:
util-linux/umount.c:87: error: `MNT_DETACH‘ undeclared (first use in this function)

make[1]: *** [util-linux/umount.o] Error 1
Makefile:741: recipe for target ‘util-linux‘ failed
make: *** [util-linux] Error 2
错误5解决办法：
umount 这里不能去掉了，因为这个功能是需要的 打开源码看看
// MNT_FORCE and MNT_DETACH (from linux/fs.h) must match // OPT_FORCE and OPT_LAZY. { typedef char bug[ (OPT_FORCE != MNT_FORCE || OPT_LAZY != MNT_DETACH) ? -1 : 1 ];
改成
// MNT_FORCE and MNT_DETACH (from linux/fs.h) must match // OPT_FORCE and OPT_LAZY. { typedef char bug[ (OPT_FORCE != MNT_FORCE || OPT_LAZY !=2 ) ? -1 : 1 ]; }
这里MNT_DETAC直接改成2
再次make

错误6解决办法：
vi ./coreutils/sync.c

* which can‘t happen here. So, no error checks.
*/
86行 syncfs(fd);
18 行 //config: bool "Enable -d and -f flags (requres syncfs(2) in libc)"
找了一个 arm-libc 中并没有这个函数
下载了 busybox-1.23.0.tar.bz2 找到同名文件，发现这个内容明显要简单很多。用 1.23 的版本替换 1.24 的。
#include "libbb.h"
/* This is a NOFORK applet. Be very careful! */
int sync_main(int argc, char **argv) MAIN_EXTERNALLY_VISIBLE;
int sync_main(int argc UNUSED_PARAM, char **argv IF_NOT_DESKTOP(UNUSED_PARAM))
{
/* coreutils-6.9 compat */
bb_warn_ignoring_args(argv[1]);
sync();
return EXIT_SUCCESS;
}
再次编译就通过了

既然编译过了，就安装上吧，执行下列指令安装。
make CONFIG_PREFIX=/work/nfs_root/first_fs install
安装上后里面有下列文件
waobot@waobot:/work/nfs_root/first_fs$ ls
bin linuxrc sbin usr
4最小根文件系统：
①/dev/console /dev/null
②init本身，即busybox
③/etc/inittab
④配置文件里指定的应用程序
⑤c库
①/dev/console /dev/null
waobot@waobot:/work/nfs_root/first_fs$ mkdir dev
waobot@waobot:/work/nfs_root/first_fs$ cd dev/
waobot@waobot:/work/nfs_root/first_fs/dev$ sudo mknod console c 5 1
[sudo] waobot 的密码：
waobot@waobot:/work/nfs_root/first_fs/dev$ sudo mknod null c 1 3
做③/etc/inittab：
做⑤c库：
waobot@waobot:/work/nfs_root/first_fs$ mkdir lib
waobot@waobot:/work/nfs_root/first_fs$ cd /work/tools/gcc-3.4.5-glibc-2.3.6/arm-linux/lib
waobot@waobot:/work/tools/gcc-3.4.5-glibc-2.3.6/arm-linux/lib$ cp *.so* /work/nfs_root/first_fs/lib -d
waobot@waobot:/work/tools/gcc-3.4.5-glibc-2.3.6/arm-linux/lib$ cd /work/nfs_root/first_fs
waobot@waobot:/work/nfs_root/first_fs$ ls
bin dev etc lib linuxrc sbin usr
最小根文件系统已经做好了
5制作yaffs映像文件，完善最小根文件系统
制作工具
waobot@waobot:/work/nfs_root/first_fs$ cd /work/system/
waobot@waobot:/work/system$ tar xjf yaffs_source_util_larger_small_page_nand.tar.bz2
waobot@waobot:/work/system$ cd Development_util_ok/
waobot@waobot:/work/system/Development_util_ok$ cd yaffs2
waobot@waobot:/work/system/Development_util_ok/yaffs2$ cd utils/
waobot@waobot:/work/system/Development_util_ok/yaffs2/utils$ pwd
/work/system/Development_util_ok/yaffs2/utils
waobot@waobot:/work/system/Development_util_ok/yaffs2/utils$ make
waobot@waobot:/work/system/Development_util_ok/yaffs2/utils$ sudo cp mkyaffs2image /usr/local/bin/
waobot@waobot:/work/system/Development_util_ok/yaffs2/utils$ sudo chmod +x /usr/local/bin/mkyaffs2image
waobot@waobot:/work/system/Development_util_ok/yaffs2/utils$ cd /work/nfs_root/
waobot@waobot:/work/nfs_root$ mkyaffs2image first_fs first_fs.yaffs2
遇到一个问题,不能启动提示：kernel panic - not syncing: No init found. Try passing init= option to kernel.
问题解决：主要原因是编译器的问题，我用的是高版本的编译器，但是库加载的是低版本的编译器。换成低版本的编译器后，改一下环境变量如下
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/work/tools/gcc-3.4.5-glibc-2.3.6/bin"
创建其他引导文件
①etc/inittab
②etc/init.d/rcS
③etc/fstab
①etc/inittab如果不想手工挂载，要加一个配置文件：
book@book-desktop:/work/nfs_root/first_fs$ vi etc/inittabconsole::askfirst:-/bin/sh::sysinit:/etc/init.d/rcS
②etc/init.d/rcS增加mdev机制 创建proc路径和sys路径
book@book-desktop:/work/nfs_root/first_fs$ vi etc/init.d/rcS#mount -t proc none /procmount -amkdir /dev/ptsmount -t devpts devpts /dev/ptsecho /sbin/mdev > /proc/sys/kernel/hotplugmdev -s
③etc/fstab
book@book-desktop:/work/nfs_root/first_fs$ vi etc/fstab#device mount-point type options dump fsck orderproc /proc proc defaults 0 0sysfs /sys sysfs defaults 0 0tmpfs /dev tmpfs defaults 0 0
到这里最小根文件系统已经很完善了
6直接从NFS启动：
重启可以看到启动参数：
bootargs=noinitrd root=/dev/mtdblock3 rootfstype=jffs2 init=/linuxrc console=ttySAC0
修改启动参数：在linux-2.6.22.6\Documentation的nfsroot.txt里面有参数的说明
nfsroot=[<server-ip>:]<root-dir>[,<nfs-options>]
ip=<client-ip>:<server-ip>:<gw-ip>:<netmask>:<hostname>:<device>:<autoconf>
bootargs noinitrd root=/dev/nfs
nfsroot=192.168.1.51:/work/nfs_root/first_fs
ip=192.168.1.11:192.168.1.51:192.168.1.1:255.255.255.0::eth0:off
init=/linuxrc console=ttySAC0
OpenJTAG> set bootargs noinitrd root=/dev/nfs
nfsroot=192.168.1.51:/work/nfs_root/first_fs
ip=192.168.1.11:192.168.1.51:192.168.1.1:255.255.255.0::eth0:off
init=/linuxrc console=ttySAC0
OpenJTAG> save
OpenJTAG> boot
到这里网络文件系统已经搭建好了，这样你可以在服务器上面编辑代码，编译，然后在单板上面运行了。
