请教：linux内核编译与编译器版本的问题

内核版本：2.6.32.2
开始编译器版本：4.3.3

编译之后内核镜像正常使用

可是把编译器版本换成4.5.1之后，编译出来的镜像不能正常使用，不知为何？


谢谢各位！

内核和文件系统都重新编绎了吗？

谢谢楼上回复，文件系统没有重新编译，我用的是nfs文件系统，这个还有关系嘛？谢谢

内核可以启动，以下是打印信息

nfs有问题，匹配问题也可能

换成4.3.3编译器可以正常启动，说明nfs是正常的

看启动代码貌似是：
文件系统启动的时候有问题，不知这两者之间有啥关联？

文件系统和内核不匹配这种问题也比较多哦

文件系统和内核的编绎器版本要一致

ok 非常感谢

重新编译了文件系统还是不能启动：

难道uboot也需要重新编译嘛？

重新编译uboot之后问题依旧：

你多大的nand，256M的要用mkyaffs2image,64M的要用mkyaffsimage_2

我用的是nfs启动不存在制作文件系统的问题吧？
