按照官方手册进行mini2440 linux移植及遇到的问题

按照”Mini2440 Linux移植开发实战指南.pdf”(2010-4-14版)来操作

一.按部就班

1.安装arm-linux-gcc 4.3.2

2.修改顶层makefile指定交叉编译变量:

原
export KBUILD_BUILDHOST := $(SUBARCH)
ARCH    ?= $(SUBARCH)
CROSS_COMPILE ?= 
改为
export KBUILD_BUILDHOST := $(SUBARCH)
ARCH    ?= arm
CROSS_COMPILE ?= arm-linux-

3.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, "Cody’s mini2440 DevBoard")。

4. 修改时钟源频率为12MHz(12000000)

5. 替换所有mach-mini2440.c中的smdk2440为mini2440,在 mini2440_machine_init(void)函数中，把
smdk_machine_init()函数调用注释掉.

6. make mini2440_defconfig然后make zImage,成功!

7. 把生成的zImage文件烧到板上运行,出现如下错误:

Copy linux kernel from 0x00060000 to 0x30008000, size = 0x00200000 ... done
zImage magic = 0x016f2818
Setup linux parameters at 0x30000100
linux command line is: "noinitrd root=/dev/mtdblock3 init=/linuxrc console=ttySA
C0"
MACH_TYPE = 1999
NOW, Booting Linux......
Uncompressing Linux.............................................................
.................................................................... done, booti
ng the kernel.

到这里就不动了,把开关拨到从Nand启动,还是出现上面几行字就不动了.

二.先不管它,按照实战手册后面的说明继续做下去.在mach-mini2440.c中加入如下代码:

/* add flash partion BY Cody */
static struct mtd_partition mini2440_default_nand_part[] = { 
        [0] = { 
                .name   = "supervivi", /*这里是 bootloader 所在的分区，可以放置 u-boot, supervivi 等内容，对应/dev/mtdblock0*/
                .size   = 0x00040000, 
                .offset = 0, 
        },
        [1] = { 
                .name   = "param", /*这里是supervivi的参数区，其实也属于bootloader的一部分，如果u-boot 比较大，可以把此区域覆盖掉，不会影响系统启动，对应/dev/mtdblock1 */
                .offset = 0x00040000, 
                .size   = 0x00020000, 
        }, 
        [2] = { 
                .name   = "Kernel",// ;内核所在的分区，大小为 5M，足够放下大部分自己定制的巨型内核了，比如内核使用了更大的Linux Logo图片等，对应/dev/mtdblock2 
                .offset = 0x00060000, 
                .size   = 0x00500000, 
        }, 
        [3] = { 
                .name   = "root", //;文件系统分区，友善之臂主要用来存放yaffs2 文件系统内容，对应/dev/mtdblock3
                .offset = 0x00560000, 
                .size   = 1024 * 1024 * 1024, // 
        }, 
        [4] = { 
                .name   = "nand", //;此区域代表了整片的nand flash，主要是预留使用，比如以后可以通过应用程序访问读取/dev/mtdblock4就能实现备份整片nand flash了。 
                .offset = 0x00000000, 
                .size   = 1024 * 1024 * 1024, // 
        } 
};
//;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, 
        }, 
}; 
//;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, 
}; 

/* End flash Partion*/

 

再修改如下信息,加入红色那一行

static struct platform_device *mini2440_devices[] __initdata = {
    &s3c_device_usb,
    &s3c_device_lcd,
    &s3c_device_wdt,
    &s3c_device_i2c0,
    &s3c_device_iis,
   &s3c_device_nand, //;把nand flash设备添加到开发板的设备列表结构
};

重新make zImage,这次出现很多错误,看不懂

baidu一下,发现有人(原文)遇到同样的错误,OK,按照原文的做,在mach-mini2440.c加入头文件,在 static void __init mini2440_map_io(void)加入红色内容

#include <linux/mtd/mtd.h>
#include <linux/mtd/nand.h>
#include <linux/mtd/nand_ecc.h>
#include <linux/mtd/partitions.h>
#include <plat/nand.h>

static void __init mini2440_map_io(void)
{
    s3c24xx_init_io(mini2440_iodesc, ARRAY_SIZE(mini2440_iodesc));
    s3c24xx_init_clocks(120000000);

    s3c_device_nand.dev.platform_data = &mini2440_nand_info;
}

再次make试试看....

还是出现错误,提示找不到mini2440_nand_info'

arch/arm/mach-s3c2440/mach-mini2440.c: In function 'mini2440_map_io':

make[1]: *** [arch/arm/mach-s3c2440/mach-mini2440.o] 错误 1

可能是分区信息在文件的后面导致找不到的原因,把第二步加入的分区信息移到最前面试试看…经过十多分钟,make成功了,把zImage下载到板上试试看

郁闷,跟第一步信息一下,到booting the kernel.就不到了. 下班了,先吃饭去,下午再回来试试.
