文件系统的制做问题

用的是supervivi和友善的zImage
自己做了个文件系统，由于自己搞的内核心一直有问题所以无法一起来
下到扳子上后出来了这个就一直不动了

给你一个忠告，不要什么都想搞一把，到最后什么都搞不好。

我不是什么都想搞，只是想整体熟悉下流程在结合讲解学习
贴出来只是想让你们前辈看看问题所在，毕竟刚刚学见的少

内核自己做最好，有很多东西别人做的不一定适合你的，如果仅仅是想做一个可以跑的内核还是比较简单的

是啊，可我得先熟悉熟悉的，
头疼的就是错的时候无从下手
问题是一个接一个

建议你解压mini2440的文件系统，参照着做（留意文件夹“dev”、“lib”、“etc”）。
看到你的贴的问题信息1、mount_devfs_fs(): unable to mount devfs, err: -2
2、Warning: unable to open an initial console.
我觉得问题很可能出在你文件系统的“etc”上，里面有3个文件的文件，是初始化用的。你参照mini做好的文件系统并结合其他书改，但不要一味照着它的。
我前两天刚弄出一个自己的文件系统，开始问题也多多，但是都是出在etc上，
另外在做文件系统时，建议不要每次直接将镜像烧入flash测试，而改用NFS挂载文件系统的方式去测试。

自己在网上百度一下哦，做一个可以用的文件系统是很简单的，做一个好的文件系统则要下一番功夫的，祝你好运！

好的,前面只把内核烧进去了,没有搞文件系统,光运行内核的话
到drivers/rtc/hctosys.c: unable to open rtc device (rtc0)

就不动了,我单独下了官方的zImage也好象到这,估计自己搞的内核没有撒问题了
但是我接着把我自己做的文件系统烧进去也是在这个地方停住了,回去还得好好研究一下文件系统的制造

你说的用nfs挂,如何测试?

停在这了,具体是错在哪,总斑竹帮忙看看啊
