我对照友善之臂的 Mini2440 Linux移植开发实战指南.pdf 进行前两部nand和yaffs2的移植，现在会出现下面的情况，高手帮忙指点一下，谢谢～！
Copy linux kernel from 0x00060000 to 0x30008000, size = 0x00500000 ... done
zImage magic = 0x016f2818
Setup linux parameters at 0x30000100
linux command line is: "noinitrd root=/dev/mtdblock3 init=/linuxrc console=ttySA
C0"
MACH_TYPE = 1999
NOW, Booting Linux......
Uncompressing Linux.............................................................
..................................................................... done, boot
ing the kernel.
