uClinux启动遇到的问题

lj124

由u-boot引导uClinux，先将其映像下载到sdram中，
tftp 0c300000 uclinux_ram.bin.gz.img
在解压缩运行，
bootm 0c300000
结果运行到
kernel command line: root=/dev/rom0 init=/linuxrc
死机！
请大家帮忙分析一下！

是遇到sti()开中断函数停了下来,猜测是u-boot的中断向量设置有问题,但修改了以后仍不行,不知道是我改的不对,还是其他的地方有问题,真是一点头绪都没有啊,有谁遇到到过类似的问题没?请指教!@_@

同样的问题，顶一下

这些问题有可能和体系相关，把你的CPU架构说一下，以及你修改过什么东西也讲讲

是怎么回事啊？
而且无法ping自己，却能ping宿主机。

看看你的rc是否有执行权限
