编译u-boot1.1.6出错，不知道咋么改。。（急）

错误代码是
我是照着韦山东那本书上编译的。。。没移植的时候编译能编译通过。。移植我是照着书上改的，修改的修改了100ask24x0.c和speed.c  自己看了很久都不知道为什么。。。。谢谢大家了
编译器我用的是3.4.5的。。。。。。。。。。。。

speed.c代码如下

dram_init 是什么函数？

在你的100ask24x0.c中就没有定义dram_init这个函数。在那里面添加下面代码试试：
int dram_init (void)
{
        gd->bd->bi_dram[0].start = PHYS_SDRAM_1;
        gd->bd->bi_dram[0].size = PHYS_SDRAM_1_SIZE;
        return 0;
}

恩，，，，，，谢谢大家了就是少了这个函数。。。。。。
