1、一、 下载源码并解压#tar xvf u-boot-2013.01.tar.bz2#cd u-boot-2013.011、 指定交叉编译工具链（在u-boot-2013.01目录下）#vi Makefile在下添加二、 指定产品BOARD（找一个相似的board配置修改，这里参照board/samsung/origen/）(1) #cp -rf board/samsung/origen/ board/samsung/fs4412(2) #mv board/samsung/fs4412/ origen.c board/samsung/fs4412/fs4412.c(3) #vi board/sa

2、msung/fs4412/ Makefile修改origen.o 为 fs4412.0(4) #cp include/configs/origen.h include/configs/fs4412.h(5) #vi include/configs/fs4412.h 修改为修改为（6）#vi boards.cfg参考添加（7） #make distclean #make fs4412_config#make ARCH=arm(8)编译生成u-boot.bin文件就是可执行的镜像文件。（9）由于samsung提供的exynos需要加密才能安全启动。(sdfuse_q与 Codesign4Secur

3、eBoot是samsung的加密文件)#cp sdfuse_q u-boot-2013.01 rf#cp Codesign4SecureBoot u-boot-2013.01 rf在u-boot-2013.01目录下的 Makefile文件的 下面添加注：必须table键缩进，否则编译将出错#cp build.sh u-boot-2013.01 rf#chmod 777 u-boot-2013.01/ build.sh#./build.sh#make fs4412_config#make ARCH=arm（编译生成u-boot-fs4412.bin,将u-boot-fs4412.bin拷贝到t

4、ftpboot目录下，烧写到开发板上：#tftp 41000000 u-boot-fs4412.bin #movi write u-boot 41000000）在 下面添加1、点灯法l 在arch/arm/cpu/armv7/start.S 134 行后添加点灯程序#if 1ldr r0, =0x11000c40 GPK2_7 led2ldr r1, r0bic r1, r1, #0xf0000000orr r1, r1, #0x10000000str r1, r0ldr r0, =0x11000c44mov r1,#0xffstr r1, r0#endif1、 添加关闭看门狗代码在beq w

6、wlevel_init.Sl 添加临时栈在lowlevel_init:后添加ldr sp,=0x02060000 use iRom stack in bl2l 添加串口初始化代码在uart_asm_init: 的strr1, r0, #EXYNOS4_GPIO_A1_CON_OFFSET 后添加ldrr0, =0x10030000ldrr1, =0x666666 ldrr2, =CLK_SRC_PERIL0_OFFSETstrr1, r0, r2ldrr1, =0x777777 ldrr2, =CLK_DIV_PERIL0_OFFSETstrr1, r0, r2注释掉trustzone初始化注

7、释掉bl uart_asm_init下的bl tzpc_init重新编译u-boot$ ./build.sh3、 网卡移植l 添加网络初始化代码$vim board/samsung/fs4412/fs4412.c在struct exynos4_gpio_part2 *gpio2; 后添加#ifdef CONFIG_DRIVER_DM9000#define EXYNOS4412_SROMC_BASE 0X12570000#define DM9000_Tacs (0x1) #define DM9000_Tcos (0x1) #define DM9000_Tacc (0x5) #define DM9
