DM8168心得之文件系統(tǒng)jffs2的制作

1、dm8168心得之文件系統(tǒng)jffs2的制作/* author: 盧浩* time: 12.03.08* environment: ubuntu10.04lts +ti dm8186* kernel version: linux-2.6.37*/首先要搭建制作jffs2的環(huán)境要下載這4個(gè)文件以下是下載鏈接1.zlib-1.2.5.tar.gz2. lzo-2.06.tar.gz 3. e2fsprogs-1.42.tar.gz 4. mtd-utils-d37fcc0.tar.gz/mtd-utils.git/snapshot/d37fcc0afd0

2、d4a14c56812847e8e4257d0a99e3b.tar.gz 下載完之后，ti的文檔里面給了兩種jffs2的，一種是給主機(jī)的，一種是個(gè)目標(biāo)板的，也是是8168的。我這里就介紹給8168用的jffs2targetthis section describes how to cross compile the mtd utilities on the linux development host for linux arm target.首先我在我建立了一個(gè)文件夾/home/user/mtd用來存放這4個(gè)壓縮文件。接下來按照以下步驟操作zlib host$ tar xvf zlib-1.

3、2.5.tar.gz host$ cd zlib-1.2.5/ host$ ./configure -prefix=/home/user/mtd/installedit resulting makefile and add toolchain prefix arm-arago-linux-gnueabi- to gcc, ldshared, cpp, ar and ranlib.這邊需要注意的是修改makefile的時(shí)候要注意對應(yīng)你當(dāng)前的編譯器，比如我用的是arm-none-linux-gnueabi-gcc,那就需要把下面的arm-arago-linux-gnueabi-gcc改成arm-n

4、one-linux-gnueabi-gcc,。否則會(huì)報(bào)錯(cuò)找不到arm-arago-linux-gnueabi-gcc host$ vi makefile cc=arm-arago-linux-gnueabi-gcc ldshared=arm-arago-linux-gnueabi-gcc -shared -wl,-soname,libz.so.1,-version-script,zlib.map cpp=arm-arago-linux-gnueabi-gcc -e ar=arm-arago-linux-gnueabi-ar rc ranlib=arm-arago-linux-gnueabi-r

5、anlibsave and close vi editor. then you should be ready to compile. host$ make host$ make install host$ cd .result should be zlib.a in /home/user/mtd/install/lib directory and zlib's headers in /home/user/mtd/install/include.lzo host$ tar xvf lzo-2.06.tar.gz host$ cd lzo-2.06/ host$ ./configure

6、-build=i686-pc-linux -prefix=/home/user/mtd/install -host=arm-arago-linux-gnueabi host$ make host$ make install host$ cd .result should be liblzo2.a in /home/user/mtd/install/lib directory and lzo's headers in /home/user/mtd/install/include/lzo.e2fsprogs host$ tar xvf e2fsprogs-1.42.tar.gz host$

7、 cd e2fsprogs-1.42/ host$ ./configure -build=i686-pc-linux -prefix=/home/user/mtd/install -host=arm-arago-linux-gnueabi host$ make host$ make install host$ cd lib/uuid/ host$ make install host$ cd ./././result should be libuuid.a in /home/user/mtd/install/lib directory and uuid's headers in /hom

8、e/user/mtd/install/include/uuid.mtd-utils host$ tar xvf mtd-utils-d37fcc0.tar.gz host$ cd mtd-utils-d37fcc0/mtd-utils don't have a configure script, so we have to edit makefile again. depending on the version of mtd utils, make sure head of top level makefile has:這邊ti的意思是把這段代碼放在makefile文件的頂端，但我編

9、譯錯(cuò)誤了，后來我嘗試放到低端，通過了。 host$ vi makefile prefix = /home/user/mtd/install zlibcppflags = -i$(prefix)/include lzocppflags = -i$(prefix)/include zlibldflags = -l$(prefix)/lib lzoldflags = -l$(prefix)/lib ldflags += $(zlibldflags) $(lzoldflags) cflags ?= -o2 -g $(zlibcppflags) $(lzocppflags) cross=arm-none

10、-linux-gnueabi-save and close vi editor. edit common.mk and comment prefix=/usr. host$ vi common.mk # prefix=/usrsave and close vi editor. then you should be ready to compile. host$ without_xattr=1 make host$ make install destdir=/home/user/mtd/install host$ cd .directory/home/user/mtd/install/sbin/ should now contain cross compiled mtd utils that can be used on target.環(huán)境搭建好了，接下來我們要制作jffs2文件系統(tǒng)rootlocalhost util# cd /home/userrootlocalhost util# mkfs.jffs2 -lqn e 128 -r target -o/tftpboot/rd-jffs2.bin這里需要注意的是，你得在你的/
