内核启动时panic了   出现这个问题有哪些因素呢,
            根文件系统已烧进去,内核存放位置0x00060000~0x00260000,根文件系统我从0x00260000开始         放置,
           根文件系统中,console 和null两个设备文件已有,,

内核问题可能较大...看下配置哦...http://www.armbbs.net/forum.php?mod=viewthread&tid=10202

还有,文件的属性哦..chmod 777 文件名..多看下教程.肯定有遗漏的步骤哦

亲，你的Nand Flash需要格式化一下，因为启动信息里面显示有很大片的连续坏块，这个太异常了。你用的u-boot不是天嵌提供的，应该是你的u-boot的yaffs烧写功能有问题引起的。

谢谢亚瑟王提醒,,,,uboot的是自己的,   这些坏块是要下载YAFFS文件系统后才有,,      
NAND的坏块只能用:
                               [1] Nand scrub - really clean NAND erasing bad blocks (UNSAFE)
  这个选项才能格式化,,


  改用天嵌提供的U-boot 后下载YAFFS 文件系统后,坏块少了一半

    但下载天嵌提供的YAFFS文件系统,坏块就没有了,可能我做的YAFFS文件有问题吧

   

我下载了,天嵌提供的文件系统,提示:

  看上面的信息出现Kernel panic - not syncing: No init found.  Try passing init= option to kernel.   
   的错误应该是文件系统没做好吧,,,  2.6.30.4 和1.7.0的Busybox 可以匹配吧?

终于可以收题了,,这个问题解决了,,,,    原因:自己编译的UBOOT 的write.yaffs命令没有写完整
  
        这么一个小小的问题难倒我个把月!         细节呀!!!
