u-boot2011.12在mini2440上的移植1

来源：互联网发布：华扬资本长期动态优化编辑：程序博客网时间：2024/06/05 04:57

        以u-boot中的smdk240为原型移植到mini2440, gcc版本4.4.3，u-boot版本2011.12
        1. 复制board/samsung/smdk2410 到board/samsung/mini2440; 将board/samsung/mini2440下的smdk2410.c重命名为mini2440.c; 修改board/samsung/mini2440的Makefile,将COBJS   := smdk2410.o改为COBJS   := mini2440.o;
        2. 复制include/configs/smdk2410.h到include/configs/mini2440.h
        3. 在根目录下的boards.cfg中添加一行，如下：

mini2440 arm arm920t - samsung s3c24x0

4. 执行

#make mini2440_config

#make

可正常编译

5. 修改mini2440.h，将

#define CONFIG_S3C2410 /* specifically a SAMSUNG S3C2410 SoC */
#define CONFIG_SMDK2410 /* on a SAMSUNG SMDK2410 Board */

    修改为
    #define CONFIG_S3C2440
    #define CONFIG_MINI2440
    #define CONFIG_SKIP_LOWLEVEL_INIT

将

#define CONFIG_SYS_PROMPT "smdk2410 # "

       修改为
   #define CONFIG_SYS_PROMPT   "mini2440 # "

       在最后添加
   #define DEBUG

       6. 修改时钟
     参照http://blog.csdn.net/reille/article/details/6539735修改start.s和mini2440.c

       7.编译，将出现如下错误：
s3c2410_nand.c: In function 's3c2410_hwcontrol':
s3c2410_nand.c:57: warning: implicit declaration of function 's3c2410_get_base_nand'

s3c2410_nand.c:154: error: dereferencing pointer to incomplete type
make[1]: *** [s3c2410_nand.o] 错误 1

      系开启nand命令所致，将#define CONFIG_CMD_NAND注释掉，名注释掉
        #define CONFIG_CMD_FAT
        #define CONFIG_CMD_EXT2
      #define CONFIG_CMD_UBI
        #define CONFIG_CMD_UBIFS
        #define CONFIG_CMD_MTDPARTS
        #define CONFIG_MTD_DEVICE
        #define CONFIG_MTD_PARTITIONS
        #define CONFIG_YAFFS2
        #define CONFIG_RBTREE

   为方便ram中执行修改#define CONFIG_SYS_TEXT_BASE   0x0 为
      #define CONFIG_SYS_TEXT_BASE   0x32000000

      编译成功，将u-boot.bin 下在到ram中（地址 0x32000000）执行出现如下效果：

第一阶段修改结束
