eboot.nb0问题？ [复制链接]

事情是这样的：
mini2440板 我自己做了一个内核，用板子带的BSP！按手册从norflash启动，先下载nboot(板子带的),eboot.nb0(自己做的)，NK.bin(自己做的)结果串口显示跳到eboot 0x30038000就不动了，但是我如果先下载nboot(板子带的),eboot.nb0(板子带的)，NK.bin(自己做的)就可以启动内核，为什么呢？自己感觉是eboot有问题
比较了以下eboot.nb0发现：
自己的eboot.nb0

往下都是00一直到00001000h，以后很长都是一样的
上面中间那么多00是不是 程序中的 跳转啊！
我的红色部分为什么不一样呢 是不是那里出问题了？
总感觉我的配置不对，可是看了好多帖子也找不到错误 好郁闷！！

有人说mini2440开发板带的是4.2的eboot,我做的是5.0的 不能用在从norflash下载的情况，是这样的吗？？

FE 03 00 EA 是跳转指令
就会跳到你的0x00001000这个地方.
