亚瑟王,求助呀，yaffs移植失败，都搞了好几天了
我根据天嵌手册一步一步移植的内核和文件系统，自己移植的内核可以与天嵌提供的root_qtopia_2.2.0_2.6.30.4_256MB_20091216.bin文件系统可以正常运行，但移植的文件系统不能运行，移植过程中用的资源都是天嵌光盘中提供的，编译器:4.33，内核:2.6.30，nandflash:256M,busybox:1.13.0,启动后出错信息如下

在此不断重复 把你的文件系统的制作步骤贴出来吧。 基本上是按"Linux移植之Step By Step_V4.2"教材中的步骤进行。
首先PC工作环境为VMware+Fedora-10-i386-DVD.iso,编译环境为EABI-4.3.3（光盘中的），编译的linux内核版本为2.6.30.4（光盘中的）,nandflash为256MB，按手册和视频教材一步步安装系统并编译内核OK，将编译的内核能和光盘提供的zImage_2.6.30.4_A70_256MB_20091030.bin下如开发板后可正常工作。下面我说一下移植yaffs2的过程，另外声明一下，所有的解压过程都是在linux工作环境中进行的。
1）下载yaffs程序包cvs-root.tar.gz,解压并安装yaffs2 OK.
2) 在menuconfig和内核原码中检查与nandflash有关的选项，因为是使用光盘中提供的linux-2.6.30.4_20091030.tar.bz2和config_EmbedSky_A70_256MB,经认真检查，确认在教材中所涉及的内容与原码和配置菜单中与不存在差异。
3）编译和安装光盘中提供的busybox-1.13.0.tar.bz2工具，检查busybox配置菜单与教材中无误，然后make;make install 编译busybox-1.13.0,在这过程中略有点错误问题，就是networking/libiproute/iptunnel.o错误,返回busybox配置菜单取消networking中iptunnel选项，保存后重新编译安装busybox OK，并在busybox1.13.0下面生成“_install”目录.
4）在/opt/EmbedSky/目录下建立一个“root_2.6.30.4”的目录,
mkdir -p /opt/EmbedSky/root_2.6.30.4
并使用下面命令建立一些目录
cd /opt/EmbedSky/root_2.6.30.4
cp -rf /opt/EmbedSky/busybox1.13.0/_install/* .
mkdir -p dev etc home/sky lib mnt/udis mnt/sd opt proc root sys tmp usr/lib usr/share var
5） 在这些目录中按教程内容建立一些文件并写入相关内容...(这里的内容反复检查过，确认无误)
包括dev目录中 建立console null
在etc目录中 建立 fstab,group,inittab,shadow,passwd,profile,mdev.conf,resolv.conf,init.d/rcS
sysconfig,rc.d,boa文件/目录，设置inittab，init.d/rcS权限
在home目录中 建立sky目录，并设置权限
在lib目录中 提取EABI-4.3.3的库文件
在mnt目录中 建立udisk和sd目录
6） 将从root_qtopia_2.2.0_2.6.30.4_20091216.tar.bz2中解压出来的root_qtopia_2.2.0_2.6.30.4\usr\bin文件中的rb rx rz sb sx sz命令文件复制到/opt/EmbedSky/root_2.6.30.4/usr/bin中
7） 使用mkyaffs2image root_2.6.30.4 root_2.6.30.4.bin命令编译文件系统
8） 检查串口驱动程序是否与教材中一致
9） 烧入内核，文件系统
总体过程大概就是这样，启动后就出现上面的错误
恳请亚瑟王指点 问题应该处在第六步，复制rx命令时出错了，busybox编译出来后自带了一个rx命令，直接复制rx命令过去是会导致busybox出错。 呵呵，和我错误一样，你把tq2440_serial0写成了tp2440_serial0。q和p写反了。 把tq写成了tp这点我还真没有注意到。呵呵。 路过做个标记学习 亚瑟王，我和楼主的操作步骤差不多，就差第六步 不过内核版本是2.6.32.2的 busybox是1.16.0的，用mkyaffs2image 制作文件后出现
这个内核我只修改加载了nandflash 网卡和串口的驱动 这个内核如果配合光盘自带的256M的文件系统能正常启动网卡 串口 nandflash 驱动
但是我按照天嵌科技出品-Linux移植之Step By Step_V4.5_20100605.pdf 制作文件系统 却出现上面问题。怎么办啊？还有一点是 那个光盘里面的
文件系统如root_qt_4.5_2.6.30.4_20100601 里面的etc/inittab文件里是 console 而手册里头确是tq2440_serial0 ,到底是哪个呢？
