一、硬件连接：

         

 

       1、16bit模式

       2、INT接到S3C2416的IRQ_LAV/EINT4，INT脚为低时为有效中断信号，中断线为EINT4；

       3、CS接到S5PV210的CSn1，CMD连接到S3C2416的地址总线ADDR[1]，故INDEX和DATA[15:0]的端口地址分别为0x80000000和0x80000004。

二、软件设定

     1、在\kernel2416\arch\arm\plat-s3c24xx\devs.c中添加如下：                   

#include <linux/dm9000.h>
#define  S3C24XX_VA_DM9000      (0xe0000000)
#define  S3C24XX_PA_DM9000      (0x08000000)
#define  S3C24XX_SZ_DM9000      SZ_1M

static struct resource dm9000_resources[] = {
    [0] = {
        .start  = S3C24XX_PA_DM9000,
        .end    = S3C24XX_PA_DM9000+0x3,
        .flags  = IORESOURCE_MEM,
    },
    [1] = {
        .start  = S3C24XX_PA_DM9000+0x4,
        .end    = S3C24XX_PA_DM9000+S3C24XX_SZ_DM9000-1,
        .flags  = IORESOURCE_MEM,
    },
    [2] = {
        .start  = IRQ_EINT4,
        .end    = IRQ_EINT4,
//      .flags  = IORESOURCE_IRQ | IORESOURCE_IRQ_HIGHEDGE,
        .flags  = IORESOURCE_IRQ | IRQF_TRIGGER_HIGH,
    },
};

static struct dm9000_plat_data dm9000_setup = {
    .flags          = DM9000_PLATF_16BITONLY
};

struct platform_device s3c_device_dm9000 = {
    .name           = "dm9000",
    .id             = 0,
    .num_resources  = ARRAY_SIZE(dm9000_resources),
    .resource       = dm9000_resources,
    .dev            =
    {
        .platform_data = &dm9000_setup,
    }
};
EXPORT_SYMBOL(s3c_device_dm9000);

#include <linux/dm9000.h> #define S3C24XX_VA_DM9000 (0xe0000000) #define S3C24XX_PA_DM9000 (0x08000000) #define S3C24XX_SZ_DM9000 SZ_1M static struct resource dm9000_resources[] = { [0] = { .start = S3C24XX_PA_DM9000, .end = S3C24XX_PA_DM9000+0x3, .flags = IORESOURCE_MEM, }, [1] = { .start = S3C24XX_PA_DM9000+0x4, .end = S3C24XX_PA_DM9000+S3C24XX_SZ_DM9000-1, .flags = IORESOURCE_MEM, }, [2] = { .start = IRQ_EINT4, .end = IRQ_EINT4, // .flags = IORESOURCE_IRQ | IORESOURCE_IRQ_HIGHEDGE, .flags = IORESOURCE_IRQ | IRQF_TRIGGER_HIGH, }, }; static struct dm9000_plat_data dm9000_setup = { .flags = DM9000_PLATF_16BITONLY }; struct platform_device s3c_device_dm9000 = { .name = "dm9000", .id = 0, .num_resources = ARRAY_SIZE(dm9000_resources), .resource = dm9000_resources, .dev = { .platform_data = &dm9000_setup, } }; EXPORT_SYMBOL(s3c_device_dm9000);

        2、在\kernel2416\arch\arm\mach-s3c2416\mach-smdk2416.c修改成：               

static struct platform_device *smdk2416_devices[] __initdata = {

    //&s3c_device_wdt,
    &s3c_device_i2c,
    &s3c_device_lcd,
    &s3c_device_rtc,
    &s3c_device_adc,
    &s3c_device_iis,
    &s3c_device_usbgadget,
    &s3c_device_usb,
    &s3c_device_hsmmc0,
    &s3c_device_hsmmc1,
    //&s3c_device_smc911x
    &s3c_device_dm9000,
};

static struct platform_device *smdk2416_devices[] __initdata = { //&s3c_device_wdt, &s3c_device_i2c, &s3c_device_lcd, &s3c_device_rtc, &s3c_device_adc, &s3c_device_iis, &s3c_device_usbgadget, &s3c_device_usb, &s3c_device_hsmmc0, &s3c_device_hsmmc1, //&s3c_device_smc911x &s3c_device_dm9000, };

   3、修改\include\asm-arm\plat-s3c24xx\devs.h ，添加:     

#if defined(CONFIG_CPU_S3C6410) || defined(CONFIG_CPU_S3C2450)|| defined(CONFIG_CPU_S3C2416)
    extern struct platform_device s3c_device_smc911x;
    extern struct platform_device s3c_device_dm9000;
#endif

#if defined(CONFIG_CPU_S3C6410) || defined(CONFIG_CPU_S3C2450)|| defined(CONFIG_CPU_S3C2416) extern struct platform_device s3c_device_smc911x; extern struct platform_device s3c_device_dm9000; #endif

   4、修改\include\linux\dm9000.h  ,添加：         

#define  S3C24XX_VA_DM9000      (0xe0000000)
#define  S3C24XX_PA_DM9000      (0x08000000)
#define  S3C24XX_SZ_DM9000      SZ_1M

#define S3C24XX_VA_DM9000 (0xe0000000) #define S3C24XX_PA_DM9000 (0x08000000) #define S3C24XX_SZ_DM9000 SZ_1M
