1、针对最新地交叉编译环境和最新地Linux内核以及最新地busybox,我用最新地交叉编译器arm-linux-gcc-4.4.1编译且移植linux-2.6.31.6和busybox-1.15.1到TQ2440开发板上.使用地u-boot是天嵌光盘中带地u-boot-1.1.6,但是我把其中地s3c2440地机器码修改为默认值,即：362,这样就不用修改Linux内核中地s3c2440地机器码了.下面是具体地移植步骤（今天我只移植了NAND、RTC、SD卡和DM9000,明天接着移植其他部分）：移植Linux-2.6.3

2、1.6到24401.从www.kernel.org下载目前Linux最新源代码包,linux-2.6.31.6.tar.bz22.解压缩linux-2.6.31.6.tar.bz2到指定地目录下,如：kernel/目录下；3.进入kernel目录（#cdkernel）；4.修改系统时钟.Linux内核默认系统时钟为16MHz,我地板子使用地时钟是12MHz地,因此需要调整系统时钟参数.打开文件arch/arm/mach-s3c2440/mach-smdk2440.c,修改smdk2440_map_io()函数中地s3c2

3、4xx_init_clocks()中地参数为12000000；5.添加NAND分区表到内核.    1)#vimarch/arm/plat-s3c24xx/common-smdk.c;    2)修改结构smdk_default_nand_part,添加自己地分区表信息.如下是我地分区表：    staticstructmtd_partitionsmdk_default_nand_part[]={                                                [0]={          

4、                                                                      .name  ="bootloader",                                                                .size  =0x00040000,                                                                  .offset=0x0,           

5、                                                     },                                                                              [1]={                                                                                .name  ="kernel",                            

6、                                        .size  =0x00200000,                                                                  .offset=0x00200000,                                                            },                                                         

7、                     [2]={                                                                                .name  ="yaffs2",                                                                    .size  =0x0FB80000,                                                     

8、             .offset=0x00400000,                                                            }
