在2410上运行2.6.14.2时无法找到rootfs, 拉兄弟一把

ctaer

我下载了2.6.14.2内核, 采用了其中自带的s3c2410配置文件, 也修改和添加了其中的flash分区信息. 但是在运行的时候无法找到启动行中指定的rootfs.
以下是内核启动讯息, 各位大侠们能否告诉我问题出在了哪里??

谢谢

无人喝彩

你的rootfs作了么 ，放在哪里了？

qld001a

是啊，根文件系统你做的是多大的？从那个地址开始？

我也碰到类似问题，谁能来指点下?

bootloader kernel rootfs 都是怎么分配的?

shyxie

看了兄弟贴出来的内核的启动日志，看来是跟我之前遇到的问题一样。。
觉得文件系统挂载不了可能是vivi传递的内核启动参数的问题，因为我将启动参数改为"noinitrd root=/dev/mtdblock3 init=/linuxrc console=ttySAC0"好像就可以挂载rootfs了，但是linux还是不能正常启动。。

下面把我的启动日志贴出来，希望各位兄弟帮忙看看。。。
