移植linux2.6问题

Question

现在在s3c2410上移植u-boot，linux2.6都完成了，网卡也可以用了，用nfs做根文件系统是可以启动的，就是挂载cramfs的时候怎么也不行，下面是log，大侠们帮忙看看啊

Kernel panic - not syncing: No init found. Try passing init= option to kernel.
其中incorrect data check是在fs/cramfs/uncompress.c中增加的zlib解压时的错误信息;
其中的try几句是我在init/main.c中增加的打印语句，
从log来看，好像cramfs已经挂载了，但是linuxrc一直都执行不了，linuxrc用脚本试过，也用busybox链接试过，都一样。
大侠们帮忙啊

羡慕中……我还没有开发板，手机MOTO E2没有驱动，也不敢做实验……

这可能是你系统起不来的原因，cramfs文件系统解压错误，所以执行不了。
顶一下，我也遇到类似的问题，请哪位大牛出来解释一下原因：

Answer 3

我的解压文件系统的问题解决了，在制作文件系统的时候，有个参数可以设置page size，当size与系统kernel的page size不匹配的时候会出错，具体可以制作文件系统的命令的帮助。

希望会对你有所帮助。
