Kernel panic - not syncing: Attempted to kill init! 你的rootfs.arm_nofpu.ext2.gz确保是好的吗？你按照下面的文档弄一个新的出来看看如何。
http://www.at91.com/linux4sam/bin/view/Linux4SAM/GettingStarted#Demo9260
对了，你弄一个rootfs放到flash里面直接mount吧。 哦,我的系统都起不来哈.我先把频率降下来再说 文件系统的问题 重命令行看，你应该是重dataflash加载跟文件系统，确认你已经将根文件系统写入到dataflash
mem=64m console=ttyS0,115200 initrd=0x21000000,0x00700000 root=/dev/ram rw debug
你的系统有nand，为什么不直接将根文件系统写入到nand？ 最好是讲讲你的bootstrap，u-boot，kernel，rootfs的配置情况。不是所有的错误都能够让人眼前一亮的。 文件系统没问题的，这个都是下一步事情，关键是内核启动都有问题，．今天把［频率降下来再说！ 恩 先把主频降下来吧，或者uboot测试下SDRAM有没有问题。 【10楼】 microcreat

看来楼主还没明白根文件系统和内核的关系，没有根文件系统的内核是不能正常工作的！
Kernel panic - not syncing: Attempted to kill init!
有这句话就表示你的多任务运行环境已经建立起来了，
checking if image is initramfs...<1>Unable to handle kernel paging request at virtual address e5900000
表示你的文件系统映像有问题。 呵呵!找到原因了，!

谢谢！楼上的！
没做根文件系统!我是看下我的系统能不能正常的起来，看到那么多乱码还有opp错误！所以就查这个原因了哦！
看到那些乱码,是由于
locks: CPU 198 MHz, master 99 MHz, main 18.432 MHz
主频高了.我降频,现在乱码就没有了!
我主频降到129M,master 降到60多M!现在内核和文件系统都起来了!
谢谢大家! 楼主你好，也遇到了和你一样的问题。请问你的内核速度是编译内核后设置的，还是在uboot中设置的？

我用的198M，也没有问题啊，129太低了吧 二层的板子，板子的尺寸又太小了。试了一下129有乱码，99M没有问题。正在改 Memory policy: ECC disabled, Data cache writeback
Clocks: CPU 148 MHz, master 74 MHz, main 18.432 MHz
这个速率没有问题，JSSF2文件系统不如yaffs系统跑的快。
总结：做成双面板没有错，有错的是面积又做的太小了，10x10。价格最便宜（省钱的工程师伤不起） starting 发表于 2012-5-5 17:48 static/image/common/back.gif

哈哈，我的板子到很大，50*20厘米 的，2层板，可惜东西没几个，连屏幕接口，按键接口都没有，不知道原来是什么人的主意做的NC板子，装机也可以减小啊，非得搞那么大 abnerle 发表于 2012-5-5 21:52 static/image/common/back.gif

9161是BGA封装的，能做成双层板挺厉害的了。只是板子的面积是大了点，面积大正好可以布等长线 从启动信息里直接找原因，
还是最快的。
以前因为不会分析启动信息，
走了不少弯路。 abnerle 发表于 2012-5-5 13:29 static/image/common/back.gif
