快速编译Linux2.6.33.3 for mini2440
  由于Linux-2.6.29开始Linux内核原生支持mini2440,所以现在移植Linux到mini2440基本只需要修正一些小BUG了。
 
  一、打上补丁
     修正:MMC的配置结构体(去除__initdata标志)、增加针对DM9000的总线配置
     修改:nand 分区表
 
文件:linux-2.6.33.3_tekkaman4mini2440_0.patch.tar.bz2
大小:1KB
下载:下载


tekkaman@MAGI-Linux:~/development/linux-2.6.33.3$ patch -p1 <../linux-2.6.33.3_tekkaman4mini2440_0.patch
patching file arch/arm/mach-s3c2440/mach-mini2440.c


二、增加Yaffs2文件系统的支持
 1、下载Yaffs2
      URL:http://www.aleph1.co.uk/cgi-bin/viewcvs.cgi/
 2、解压Yaffs2并将其加入Linux内核(打补丁的方式)
       #cd yaffs2
       #./patch-ker.sh c <内核源码路径>

tekkaman@MAGI-Linux:~/development/yaffs2$ ./patch-ker.sh c ../linux-2.6.33.3/
Updating ../linux-2.6.33.3//fs/Kconfig
Updating ../linux-2.6.33.3//fs/Makefile


三、编译
  
请先确保系统可以找到你的编译工具链

make ARCH=arm CROSS_COMPILE=arm-tekkaman-linux-gnueabi- mini2440_defconfig
make ARCH=arm CROSS_COMPILE=arm-tekkaman-linux-gnueabi- menuconfig

增加Yaffs2支持。

      Miscellaneous filesystems -->
       <*> YAFFS2 file system support

make ARCH=arm CROSS_COMPILE=arm-tekkaman-linux-gnueabi-


四、使用U-boot的mkimage来处理zImage:

mkimage -n 'tekkaman' -A arm -O linux -T kernel -C none -a 0x30008000 -e 0x30008040 -d zImage zImage.img


五、测试zImage.img:
