请教亚瑟王：关于nand烧写系统后不能启动而且反复重启的问题

操作步骤：
在nor flash下
选择  1> 烧写F:\tq2440\bootloader合集\EmbedSky_boot_20091031\EmbedSky_boot_Data\DebugRe了\EmbedSky_boot.bin
然后选择3>烧写内核，内核为光盘下F:\tq2440\Linux资源\Linux源码包\2.6.30.4在ubuntu上自己编译的，

然后选择6>烧写文件系统F:\tq2440\出厂烧录镜像合集\Linux文件系统镜像下所有256M的文件都试了一遍，最后得结果都是

最后它是反复的重启，间隔时间大约是2分钟不到

还是没人回答！

1、你的Nand Flash容量是多大的？是256MB的吗？
2、内核的配置单建议参考天嵌科技提供的配置单。

NAND 是256M的
内核就是用的天嵌光盘里带的，我没坐改变,只是自己重新编译了一下，因为光盘里没有编译好的内核镜像！

光盘里面提供了编译好的内核镜像啊，在出厂镜像烧录合集里面的啊。
你在uboot下载模式使用：命令q->nand info，然后查看一下Nand的容量。

EmbedSky> nand info

然后 关机，开关打到nand flash 启动

LCD 显示很乱，过会后自动重新启动！现象上上面一样！

哈哈 可以了，原来是编译内核和文件系统的编译器不同导致的！谢谢亚瑟王！

TQ2440的Linux移植教程里面多次强调交叉编译器要匹配的啊。
