NFS方式烧写系统

一、烧写厂家提供系统

1、烧写u-boot
nfs 30000000 192.168.183.128:/home/share/jz2440/source/supply/u-boot.bin

nand erase.part u-boot

nand write 30000000 u-boot

2、烧写uImage（使用的是u-boot-1.6.2）

nfs 30000000 192.168.183.128:/home/share/jz2440/source/supply/uImage

nand erase kernel

nand write 30000000 kernel

3、烧写yaffs2文件系统

nfs 30000000 192.168.183.128:/home/share/jz2440/source/supply/fs_mini_mdev.yaffs2

nand erase rootfs

nand write.yaffs 30000000 260000 $(filesize)

4、设置启动参数

set bootargs console=ttySAC0,115200 root=/dev/mtdblock3

boot

ifconfig eth0 192.168.183.127 up

mount -t nfs -o nolock,vers=2 192.168.183.128:/home/share/jz2440/source /mnt

成功

5、以nfs启动

首先将fs_mini_mdev/etc/init.d/rcS里的ip地址改成：192.168.183.127

set bootargs noinitrd console=ttySAC0,115200 root=/dev/nfs nfsroot=192.168.183.128:/home/share/jz2440/source/supply/fs_mini_mdev ip=192.168.183.127:192.168.183.128:192.168.183.225:225.225.225.0::eth0:off init=/linuxrc

boot

成功，如果不成功的话，插拔网线，多试几次！！！

二、烧写自己制作的系统

1、烧写u-boot
nfs 30000000 192.168.183.128:/home/share/jz2440/source/my/u-boot.bin

nand erase.part u-boot

nand write 30000000 u-boot

2、烧写uImage

nfs 30000000 192.168.183.128:/home/share/jz2440/source/my/uImage

nand erase.part kernel

nand write 30000000 kernel

3、烧写yaffs2文件系统

nfs 30000000 192.168.183.128:/home/share/jz2440/source/my/fs_mini_mdev_new.yaffs2

nand erase.part rootfs

nand write.yaffs 30000000 260000 $filesize

4、设置启动参数

set bootargs console=ttySAC0,115200 root=/dev/mtdblock3

boot

mount -t nfs -o nolock,vers=2 192.168.183.128:/home/share/jz2440/source /mnt

成功

5、以nfs启动

首先将fs_mini_mdev/etc/init.d/rcS里的ip地址改成：192.168.183.127

set bootargs console=ttySAC0,115200 root=/dev/nfs nfsroot=192.168.183.128:/home/share/jz2440/source/my/fs_mini_mdev_new ip=192.168.183.127:192.168.183.128:192.168.183.225:225.225.225.0::eth0:off init=/linuxrc

boot

成功！
