u-boot2011.12 transplantation on mini24401

Based on smdk240 in u-boot, ported to mini2440, gcc version 4.4.3, u-boot version 2011.12

1. Copy board/samsung/smdk2410 to board/samsung/mini2440; Rename smdk2410.c under board/samsung/mini2440 to mini2440.c; Modify the Makefile of board/samsung/mini2440, change COBJS := smdk2410.o to COBJS := mini2440.o;

2. Copy include/configs/smdk2410.h to include/configs/mini2440.h

3. Add a line to boards.cfg in the root directory as follows:

          mini2440                   arm         arm920t     -                   samsung        s3c24x0

4. Execution

#make mini2440_config

#make

Can compile normally

5. Modify mini2440.h,

         #define CONFIG_S3C2410        /* specifically a SAMSUNG S3C2410 SoC */

         #define CONFIG_SMDK2410        /* on a SAMSUNG SMDK2410 Board */

        change into

        #define CONFIG_S3C2440

        #define CONFIG_MINI2440

        #define CONFIG_SKIP_LOWLEVEL_INIT

       Will

        #define CONFIG_SYS_PROMPT    "smdk2410 # "

       change into

       #define CONFIG_SYS_PROMPT    "mini2440 # "

       Add at the end

       #define DEBUG

6. Modify the clock

Refer to http://blog.csdn.net/reille/article/details/6539735 to modify start.s and mini2440.c

7. Compile, the following error will appear:

s3c2410_nand.c: In function 's3c2410_hwcontrol':

make[1]: *** [s3c2410_nand.o] Error 1

        This is caused by turning on the nand command. Comment out #define CONFIG_CMD_NAND and name.

        #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

       To facilitate execution in ram, modify #define CONFIG_SYS_TEXT_BASE 0x0 to

      #define CONFIG_SYS_TEXT_BASE    0x32000000

      The compilation is successful, and u-boot.bin is downloaded to ram (address 0x32000000) and the execution results are as follows:
