《Mini2440_Linux移植开发实战指南》nandflash驱动移植（修改）

 

今晚根据《Mini2440_Linux移植开发实战指南》一文进行nandflash驱动
的移植出现了不少问题。不知道是我操作失误还是该文编写出现错漏导致的。
    首先按照步骤修改相关信息之后执行make zImage出现了不少错误，找了好多资料才弄好，但是为什么那么弄不知道原因。

    1、增加头文件：

   

#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>

    2、增加文档中说的三个结构：

   

static struct mtd_partition mini2440_default_nand_part[] = {
    [0] = {
        .name    = "supervivi",
        .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, //
    },
    [4] = {
        .name    = "nand",
        .offset  = 0x00000000,
        .size    = 1024 * 1024 * 1024, //
    }
};
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,
    },
};
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,
};

3、增加这三个结构之后修改如下代码

static struct platform_device  *mini2440_devices[] __initdata = {
    &s3c_device_ohci,
    &s3c_device_lcd,
    &s3c_device_wdt,
    &s3c_device_i2c0,
    &s3c_device_iis,
    &s3c_device_nand, //增加部分
};

4、最后在在修改如下结构

 

static void __init mini2440_map_io(void)
{
    s3c24xx_init_io(mini2440_iodesc, ARRAY_SIZE(mini2440_iodesc));
    s3c24xx_init_clocks(12000000);
    s3c24xx_init_uarts(mini2440_uartcfgs, ARRAY_SIZE(mini2440_uartcfgs));
    s3c_device_nand.dev.platform_data = &mini2440_nand_info; //增加的部分
}

 

最后一编译果然通过了

  CHK include/generated/utsrelease.h

之后将编译好的内核下载到开发板运行

这样就能看到移植的Nand的一些信息了，到此内核就移植好了，下一步学习移植yaffs2,还不知道这是个什么东东呢？
