我使用的不是天嵌科技制作的Linux2.6.30.4 ,是自己下载的Linux2.6.30.4内核。bootloader用的天嵌的。感觉应该是内核设置的问题,因为使用天嵌的zImage可以启动自己的文件系统。不知道问题出在哪了?

在启动的打印消息中NET: Registered protocol family 1下面米有

yaffs Jun 28 2016 13:51:49 Installing. 这句话

这是什么原因呀

我的yaffs2也是自己下载的 会不是是yaffs2的问题?
 楼主| wuzhisi 发表于 2016-7-4 14:36:08 | 显示全部楼层
应该是yaffs2的移植问题。
./patch-ker.sh c m //应该选m参数。
选错了的话需要把yaffs2文件夹删了重新打补丁。
不删除文件夹好像是不行的
