错误1：
dm9000 dm9000: wrong id: 0x2b2a2928
dm9000 dm9000: not found (-19).
正常打印：
eth0: dm9000a at c4862300,c4864304 IRQ 51 MAC: 00:0c:20:02:0a:5b (chip)
原因是S3C24XX_PA_DM9000的地址定义错了，应该是0x18000300，错定义为0x20000300


错误2：

修改common-smdk.c的smdk_default_nand_part为
static struct mtd_partition smdk_default_nand_part[] = {
   [0] = {
       .name = "bootloader", 
       .offset = 0x00000000, 
       .size = 0x00060000, 
   },
   [1] = { 
       .name = "kernel", 
       .offset = 0x00060000, 
       .size = 0x00300000, 
   },
   [2] = { 
       .name = "root", 
       .offset = 0x00360000, 
       .size = 0x3c9c000,

添加yaffs2文件系统
最新的yaffs2采用git发布，所以采用git工具下载最新的yaffs2源代码。


具体为在终端输入git clone    git://www.aleph1.co.uk/yaffs2下载最新的yaffs2，下


载完成给内核打补丁，进入yaffs目录，执行
 ./patch-ker.sh c m opt/Andy/linux-3.0.4（以自己的内核目录为准）,其中的c代表复制，m代表复合类型。


配置内核选中yaffs2
打印
Failed to execute /linuxrc.  Attempting defaults...
待解决

错误4：使用NFS文件系统
dm9000: WARNING: no IRQ resource flags set
解决：[2] = {.start = IRQ_EINT9,.end   = IRQ_EINT9,.flags = IORESOURCE_IRQ | IORESOURCE_IRQ_HIGHEDGE,}};
加了IORESOURCE_IRQ_HIGHEDGE就解决了，不知何故
