我现在把那个取消了。。试试看可以出调试信息不。。。希望可以。。。

啊哈哈。。找到原因了。。。机器ID的事！！

啊哈哈。。
Error: unrecognized/unsupported machine ID (r1 = 0x0000030e).

Available machine support:

ID (hex)        NAME
000007cf        MINI2440
我去修改一下。。我看到希望了。。啊哈~

真不错，绕了一圈终于又回到起点了

我修改了arch/arm/tools/mach-types中的

s3c2440 ARCH_S3C2440 S3C2440 1999

还是不行..还是显示我的机器ID是782

还有个问题..我调用的是mach-mini2440.c啊...这里面MACHINE_START(MINI2440,"MINI2440")调用的是MINI2440啊。。MINI2440在mach-types注册的ID就是1999为何初始化输出还是782呢？

后来我有把mach-types里面782对应的一个板子改成了1999了。。还是不行。。现在那个文件里面都没有782这个ID了。。还显示输出我的机器ID是782。。疯掉了。。。

不过今天还是又收获的。一切又回到了原点。。但是又好象不是原点。。

明天12节还有课。。明天继续。。真的跟感谢你kasim..

再正确理解一下内核告诉你的信息:
Error: unrecognized/unsupported machine ID (r1 = 0x0000030e).  ===> bootloader(即Supervivi) 传递给内核的mach_type, 转成十进制是782

Available machine support:

ID (hex)        NAME
000007cf        MINI2440        ===> 编译出来的内核中支持的硬件平台所对应的mach_type，转成十进制是1999

呃..昨天晚上改错了...应该是把MINI2440的改成782才是...
现在可以启动内核了..啊哈哈~
但是分区还有问题

我改下分区..希望这次可以咯..好期待...

啊啊啊啊!!!改了分区。。YAFFS正常启动了..但是又有新问题了...Unable to handle kernel paging request at virtual address 626f2038内核无法处理虚拟地址的请求?什么意思咯...我研究一下Oops信息...按书上讲的分析一下..看可以找到解决办法不...

Kernel panic - not syncing: Attempted to kill init!

看样子是在调用s3c2410_nand_select_chip出错了...我去配置内核看看怎么回事...

重新配置了一下出现了新问题....检查出一大堆坏块..

难道是ECC的问题?

------------------------------------------------------------------------
关闭了ECC这个问题解决了..但是还是那个s3c2410_nand_select_chip有问题。。不晓得怎么办了。。。

为何在选择NAND FLASH那出问题呢......kasim 大师快现身...我想不出了...555555555
