我的linux kernel 2.6 at skyeye过程

hquatoy

我的主机环境是redhat9.0+skyeye0.7.0
编译环境使用http://www.linuxforum.net/上oslinux朋友提供的方法
1.首先在http://handhelds.org/download/toolchain/arm-linux-gcc-3.3.2.tar.bz2
下载 arm-gcc 3.3.2
2.将arm-linux-gcc-3.3.2.tar.bz2 解压到 /toolchain
# tar jxvf arm-linux-gcc-3.3.2.tar.bz2
# mv /usr/local/arm/3.3.2 /toolchain
3. 在http://handhelds.org/download/toolchain/arm-linux-toolchain-post-2.2.13.tar.gz
下载arm-linux-toolchain-post-2.2.13.tar.gz
4. 将arm-linux-toolchain-post-2.2.13.tar.gz 解压到 /skiff/local/ 下
# tar zxvf arm-linux-toolchain-post-2.2.13.tar.gz
5. 拷贝头文件到/toolchain/arm-linux/ 下. 然后删除 /skiff
# cp -dR /skiff/local/arm-linux/include /toolchain/arm-linux/
# rm -fr /skiff
6. ok! arm linux 2.6 的交叉编译环境建立好了！ 下面设置cross compiler 时要用到/toolchain/bin/arm-linux-
7. 下载http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.5.tar.bz2
和ftp://ftp.arm.linux.org.uk/pub/armlinux/source/kernel-patches/v2.6/patch-2.6.0-rmk2.bz2
8.解压到linux目录下并打好补丁；
9.修改linux/Makefile文件，修改ARCH=arm并设置Cross Compiler，设置为第6步的/toolchain/bin/arm-linux- ，如果路径不同，要进行相应修改；
10.修改setup.c，设置Kernel Command Line；
11.运行make gconfig，定制内核，去掉不需要的设置，然后编译armlinux，
根据chenyuu大侠的在公社上转贴的信息，不用修改就可以在skyeye上运行，
可是我运行到starting就停住了，估计还要修改init的设置。
尽管没有做成，但我会继续研究，如果试成功了，就共享。同时，也希望
大侠如果有发现过程有错误或遗落的，就回个贴，期待共同进步。

第10步，不用修改setup.c文件，在设置的时候有个选项，Default kernel command string，在如下
General setup  --->
     Default kernel command string

在Default kernel command string中写入你的cmd_line，我成功的例子是：
root=/dev/ram0 console=ttyCL0 initrd=0xc0200000,0x00200000 rw
如果启动不了，很可能是你的配置没有设对。你的配置是clps711x/ep7312么？
关键的地方是如下两项，：
CONFIG_ARCH_CLPS711X=y
CONFIG_ARCH_CLEP7312=y
应该不需要任何改动的。实在不行，把你的.config发给我看看。

以下是我的.config,编译成vmlinux我直接拷贝到ep7312/linux1,
ep7312/linux2及其他ep7312下的目录运行,我按照王大侠的指点

启动的时候说
checking if image is initramfs...it isn't (ungzip failed); looks like an initrd
或者
checking if image is initramfs...it isn't (no cpio magic); looks like an initrd

这个initrd要怎么做？

我是用
#dd if=/dev/zero of=initrd bs=1k count=200
#mke2fs initrd

然后把东西拷到initrd里面
