S3C6410(arm11核)的DM9000移植

 
第一步 配置内核
             
[*] Networking support  ---> 
       Networkingoptions  --->  
              [*]TCP/IP networking
Device Drivers  --->
                     [*]Network device support  --->
                     [*]   Ethernet (10 or 100Mbit)  --->
                            <*>   DM9000 support
             
第二步 配置参数
（1）
#include <linux/dm9000.h>
// ANW6410_PA_DM9000根据电路图中使用的片选决定
#define ANW6410_PA_DM9000  (0x18000000)
static struct resourceanw6410_dm9000_resource[] = {
       [0]= {
              .start= ANW6410_PA_DM9000,
              .end   = ANW6410_PA_DM9000 + 3,
              .flags= IORESOURCE_MEM,
       },
       [1]= {
              .start= ANW6410_PA_DM9000 + 4,
              .end   = ANW6410_PA_DM9000 + 4 + 500,
              .flags= IORESOURCE_MEM,
       },
       [2]= {
              .start= IRQ_EINT(7),
              .end   = IRQ_EINT(7),
              .flags= IORESOURCE_IRQ | IRQF_TRIGGER_HIGH,
       },
};
 
static struct dm9000_plat_dataanw6410_dm9000_pdata = {
       .flags        =(DM9000_PLATF_16BITONLY | DM9000_PLATF_NO_EEPROM),
       /*dev_addr can be set to provide hwaddr. */
};
 
static struct platform_deviceanw6410_device_eth = {
       .name      = "dm9000",
       .id   = -1,
       .num_resources      = ARRAY_SIZE(anw6410_dm9000_resource),
       .resource = anw6410_dm9000_resource,
       .dev = {
              .platform_data  = &anw6410_dm9000_pdata,
       },
};
 
在anw6410_machine_init中调用anw6410_dm9000_enable();
（4）
static struct platform_device*anw6410_devices[] __initdata = {
       &s3c_device_fb,
       &anw6410_lcd_powerdev,
       &anw6410_device_eth,
       &s3c_device_nand,
};
 
移植中遇到的问题：
1.移植dm9000
开发板ping电脑时，系统死掉，提示以下错误

原因已找到
是和其它设备配置起冲突导致出现这个问题
