U-BOOT引导Linux-2.6.32内核进入文件系统

原文地址：U-BOOT引导Linux-2.6.32内核进入文件系统 作者：sweet-smile

自己的内核有了，文件系统也有了，该是用u-boot的时候了，哈哈。

查看主机IP

比较奇葩的ip，哈哈。学校的网，正常的。

在vivi菜单中，分别下载u-boot，uImage，rootfs.img
选择NAND启动，启动之前按任意键进入U-BOOT命令模式，根据主机和需要设置U-BOOT参数并保存：

########其实此时IP不是重点，咱不是从NAND启动嘛#########
uImage和rootfs.img都是经过验证正确无误，u-boot参数也保存了，此时我直接重启开发板，应该是直接自启动了吧，于是复位重启！
错误出现了，居然没有正常启动 !!!

u-boot，uImage，rootfs.img都在里边了，为什么不行呢？让他们继续在NandFlash里待着吧！
利用交叉网线将开发板和电脑相连，启动开发板并进入U-BOOT命令模式，做如下工作：
（1）利用tftp命令下载内核到内存0x31000000
（2）使用nand erase命令擦除kernel分区（0x00060000-0x00500000）
（3）使用nand write命令将刚下载到内存0x31000000处的uImage写入kernel分区（0x00060000-0x00500000）
（4）启动内核：bootm 0x31000000,此时内核启动成功，并成功进入文件系统，O(∩_∩)O哈哈~

重启开发板，此时开发板可以自启动并成功进入我们自己的文件系统！至此u-boot已经成功引导内核，内核成功启动文件系统。
下来实现nfs挂载文件系统，便于以后的学习和开发！！！
