按照友善的Linux移植开发指南移植，具体步骤如下：一、指定交叉编译变量修改总目录下的Makefile原export KBUILD_BUILDHOST := $(SUBARCH)ARCH ?= $(SUBARCH)CROSS_COMPILE ?=改为export KBUILD_BUILDHOST := $(SUBARCH)ARCH ?= armCROSS_COMPILE ?= arm-linux-执行：#make s3c2410_defconfig ;使用缺省内核配置文件,s3c2410_defconfig 是SMDK2440 的缺省配置文件#make ;编译时间较长编译通过二、将linux-2.6.32.2/arch/arm/mach-s3c2440/目录下的mach-smdk2440.c 复制一份。命名为mach-mini2440.c ， 找到MACHINE_START(S3C2440, "SMDK2440") ， 修改为MACHINE_START(MINI2440, "FriendlyARM Mini2440 development board")。三、修改时钟源频率行static void __init smdk2440_map_io(void)函数中把其中的16934400改为12000000四、从SMDK2440 到MINI2440，因此把mach-mini2440.c 中所有的smdk2440 字样改为mini2440，可以使用批处理命令修改，在vim 的命令模式下输入：%s/smdk2440/mini2440/g在mini2440_machine_init(void)函数中，把smdk_machine_init()函数调用注释掉五、编译测试#make mini2440_defconfig ;使用Linux 官方自带的mini2440 配置#make zImage ;编译居然出现 invalid option `abi=aapcs-linux'错误 cc1: error: invalid option `abi=aapcs-linux' make[1]: *** [arch/arm/kernel/asm-offsets.s] Error 1 make: *** [prepare0] Error
换编译器Sourcery G++ Lite 2010q1-202（支持EABI)
修改Makefile
CROSS_COMPILE ?= arm-none-linux-gnueabi-
重新编译#make zImage；编译成功
六、在Linux-2.6.32.2/arch/arm/mach-s3c2440/Makefile中添加
obj-$(CONFIG_MACH_MINI2440) += mach-mini2440.o
七、移植Nand 驱动并更改分区信息
1、修改Nand Flash 分区表
参考/arch/arm/plat-24xx/common-smdk.c
在mach-mini2440.c添加友善的nand分区表

static struct mtd_partition mini2440_default_nand_part[] = { [0] = { .name = "vivi",   .size = 0x00040000, .offset = 0, }, [1] = { .name = "param", .offset = 0x00040000, .size = 0x00020000,   }, [2] = { .name = "Kernel", .offset = 0x00060000, .size = 0x00500000, }, [3] = { .name = "root", .offset = 0x00560000, .size = 1024 * 1024 * 1024, }, [font=] [4] = { .name = "nand", .offset = 0x00000000, .size = 1024 * 1024 * 1024, } }; [font=]

2、加NandFlash的设置表。//这里是开发板的nand flash 设置表，因为板子上只有一片，因此也就只有一个表
static struct s3c2410_nand_set mini2440_nand_sets[] = {
[0] = {
.name = "NAND",
.nr_chips = 1,
.nr_partitions = ARRAY_SIZE(mini2440_default_nand_part),
.partitions = mini2440_default_nand_part,
},
};
3、//这里是nand flash本身的一些特性，一般需要对照datasheet填写，大部分情况下按照以下参数填写即可
static struct s3c2410_platform_nand mini2440_nand_info = {
.tacls = 20,
.twrph0 = 60,
.twrph1 = 20,
.nr_sets = ARRAY_SIZE(mini2440_nand_sets),
.sets = mini2440_nand_sets,
.ignore_unset_ecc = 1,
};
在mini2440_machine_init函数中添加平台的数据信息。
 

static void __init mini2440_machine_init(void){ s3c24xx_fb_set_platdata(&mini2440_fb_info); s3c_i2c0_set_platdata(NULL); s3c_device_nand.dev.platform_data = &mini2440_nand_info;  //添加 platform_add_devices(mini2440_devices, ARRAY_SIZE(mini2440_devices)); }

编译失败，按照/arch/arm/plat-24xx/common-smdk.c
在该文件中添加几个头文件才能编译成功：
#include <linux/mtd/mtd.h>
#include <linux/mtd/nand.h>
#include <linux/mtd/nand_ecc.h>
#include <linux/mtd/partitions.h>
#include <plat/s3c2410.h>
#include <plat/s3c2440.h>
#include <plat/clock.h>
#include <plat/devs.h>
#include <plat/cpu.h>
#include <plat/nand.h>  //添加
八、移植yaffs21、#git clone git://www.aleph1.co.uk/yaffs22、为内核打上yaffs2 补丁#cd yaffs2#./patch-ker.sh c m /opt/FriendlyARM/mini2440/linux-2.6.32.23、配置和编译带YAFFS2 支持的内核根目录运行：make menuconfigFile Systems->Miscellaneous filesystems->YAFFS2 file system support按空格选中#make zImage;编译成功九、下载，启动失败启动时，终端输出信息如下：load Image of Linux...Uncompressing Linux.......................................

在网上看了几个版本，发现漏了
在mini2440_machine_init函数中添加平台的数据信息！！！

static void __init mini2440_machine_init(void){
s3c24xx_fb_set_platdata(&mini2440_fb_info);
s3c_i2c0_set_platdata(NULL);
s3c_device_nand.dev.platform_data = &mini2440_nand_info;  //添加后，编译下载，启动成功
platform_add_devices(mini2440_devices, ARRAY_SIZE(mini2440_devices));
}
我的移植指南可能太旧了 !!!

   谢谢分享

新手，想问下lz移植内核是不是用jlink仿真器直接把bin文件烧进去就好。。求详解，纠结了好久
