问题已经解决 手册45页命令mkyaffsimage_2是对于Linux2.6.25.8 的
如果是Linux—2.6.30.4要用mkyaffs2mage
但是现在又出现这个问题
ailed to execute /linuxrc.  Attempting defaults...
': No such file or director
can't open /dev/tq2440_serial0: No such file or director

你搞错了mkyaffsimage_2是对64MB的Nand Flash的，mkyaffs2image是对256MB的Nand Flash的。
内核或文件系统是你自己做的？

是的内核文件是自己做的
显示yaffs_read_super: isCheckpointed 0

检查你的文件系统的etc/inittab中的串口设置，如果你移植串口时使用的是tq2440_serial，对应在文件系统中也应该使用tq2440_serial

我移植的是Linux_2.6.30.4 我试了用tq2440_serial不行我在试其它的# /etc/inittab
::sysinit:/etc/init.d/rcS
tq2440_serial::askfirst:-/bin/sh
::once:/usr/sbin/telnetd -l /bin/login
::ctrlaltdel:/sbin/reboot
::shutdown:/bin/umount -a -r

tq2440_serial0::askfirst:-/bin/sh
应该加上0，标识使用第一个串口作为控制台。
