ubifs文件系统的制作以及移植

来源：互联网发布：网络监控画面时有时无编辑：程序博客网时间：2024/05/21 17:40

修改根文件系统：

[lingyun@localhostetc]$ vim mdev.conf

sd[a-z][0-9] 0:0 0777 @(mount /dev/$MDEV /mnt/usb)

sd[a-z] 0:0 0777 $(umount /mnt/usb)

#ub[a-z][0-9] 0:00777 @(mount /dev/$MDEV /mnt/usb)

#ub[a-z] 0:00777 $(umount /mnt/usb)

mmcblk[0-9]p[0-9]0:0 0777 @(mount /dev/$MDEV/mnt/sdc)

mmcblk[0-9] 0:0 0777 $(umount /mnt/sdc)

将etc/inittab文件中的下面两行注释掉。

#Mountour apps/info partition

[lingyun@localhostetc]$ vim inittab

……

#null::wait:/bin/mount -o sync,noatime,ro -t jffs2 /dev/mtdblock6/apps

#null::wait:/bin/mount -o sync,noatime,ro -t jffs2/dev/mtdblock7 /info

……

制作镜像文件：

前面在制作mkfs.jffs2工具的同时制作了一个mkfs.ubifs工具，这个工具就是用来制作ubifs映像的一个工具。

[lingyun@localhostmtd-utils-1.4.9]$ ls mkfs.ubifs/

compr.c compr.o crc16.c crc16.o devtable.c hashtable lpt.c lpt.o mkfs.ubifs.c mkfs.ubifs.o ubifs.h

compr.h COPYING crc16.h defs.h devtable.o key.h lpt.h mkfs.ubifs mkfs.ubifs.h README ubifs-media.h

[lingyun@localhostmkfs.ubifs]$ sudo cp mkfs.ubifs /usr/bin/

因为mkfs.ubifs工具制作的文件系统映像，在uboot中烧录这种映像文件的方式过于复杂，既要使uboot支持nandflash分区，又要在uboot中激活这个分区，再通过ubi write命令烧录这个映像。所以我们换一种比较容易的方式来移植这个文件系统

在制作mkfs.jffs2和mkfs.ubifs工具时，其实还有一个ubinize工具是同时生成的，它的作用是将mkfs.ubifs制作的映像转换为可以直接用nand write命令烧录的映像文件。

[lingyun@localhostmtd-utils-1.4.9]$ cd ubi-utils/

[lingyun@localhostubi-utils]$ ls

rootfs.ubifs的制作过程是通过下面的shell脚本完成的：
