............后面就一直这样，启动不起来。

 ===============================================

解决方法：

 

1，kernel 配置

 

Network File Systems                                                                    x x 
  x x                      <*>   NFS client support                                                                    x x 
  x x                      [*]     NFS client support for NFS version 3                                                x x 
  x x                      [ ]       NFS client support for the NFSv3 ACL protocol extension                           x x 
  x x                      [ ]     NFS client support for NFS version 4 (EXPERIMENTAL)                                 x x 
  x x                      [*]     Root file system on NFS                                                             x x 
  x x                      < >   NFS server support          

 

选上Root file system on NFS

 

2，在uboot下设置参数

内核启动参数参见Documentation/kernel-parameters.txt
它说 ip 这个选项
See Documentation/filesystems/nfs/nfsroot.txt.

ip=<client-ip>:<server-ip>:<gw-ip>:<netmask>:<hostname>:<device>:<autoconf>

我的配置：

setenv bootargs 'console=ttymxc0,115200 init=/init androidboot.console=ttymxc0 root=/dev/nfs rw nfsroot=192.168.5.107:/tftpboot/rootfs ip=192.168.5.53:192.168.5.107:192.168.5.10:255.255.255.0:skypine:eth0:on rw  di1_primary calibration'

 

3，nfs作为根是起来了。可能是启动顺序的不一致吧，原来作为jffs2启动的镜像改成nfs就会报
Warning: unable to open an initial console.

这个主要是没有建立控制台，解决方式：

缺少 /dev/console 和 /dev/null
在建立他們之前UDEV就先使用到他們了

cd /dev
mknod -m 660 console c 5 1
mknod -m 660 null c 1 3
