我在网上也看了很多关于这些问题，但是怎么改还是不行，其中论坛里有个帖子也有这个问题的解释，
http://bbs.embedsky.net/forum.php?mod=viewthread&tid=6422
但是我做了还不行，我有两个疑问：1.我的内核编译是不是有问题啊？2.我的文件系统那里配置错了啊？我编译完内核时，我自己的内核不会有重启的现象？
求教？？？？？？？
从你打印的信息来看，你的内核说没有发现文件系统，说明你的yaffs应该没有移植成功。参考手册把yaffs的移植做一下。后面No init found的情况在漏做手册中创建/dev/console和/dev/null两个设备文件时会出现，检查一下有没有做这个步骤？ 不好意思搞错了，如果是没做那两个文件不会引起No init found，只会Warning: unable to open an initial console. 建议你把你自己做的文件系统打包以后发上来大家帮你看一下 wuweidong 发表于 2012-5-1 21:18 static/image/common/back.gif
No filesystem could mount root,
uboot的bootargs没设置对或者yaffs没有烧写到对应的地方
我觉得如果是写错地方的话用天嵌的烧写程序无论是哪个命令来烧写都会覆盖内核，内核好像都无法启动？如果用错了文件系统的制作程序应该会出现大量的逻辑坏块，这里却看不到。因此楼主很可能在烧写天嵌内核的时候把整个nandflash格式化了，然后把天嵌的内核烧入了nandflash却没有进一步的烧写文件系统。结果校验的时候由于文件系统全部都是FF，所以不会出现大量的坏块，但是入口却没有任何程序。
个人认为楼主应该做一下以下检查：
1、注意制作yaffs文件系统和移植yaffs文件系统驱动是两回事，检查烧入天嵌内核以后是否有烧入文件系统？
2、如果已经移植成功yaffs驱动的话，无论文件系统中的数据是否正确，内核都会启动yaffs来加载文件系统。而且无论使用什么启动参数都应该会显示yaffs Nov 11 2011 20:57:33 Installing. 之类的信息。但是这里却显示No filesystem could mount root，而且没有yaffs Nov 11 2011 20:57:33 Installing. 之类的信息，说明楼主应该根本没移植成功yaffs文件系统驱动。具体为什么没有移植成功只能让楼主自己描述一下移植的过程了。 guoke25 发表于 2012-5-2 01:50 static/image/common/back.gif

“如果已经移植成功yaffs驱动的话，无论文件系统中的数据是否正确，内核都会启动yaffs来加载文件系统”不好意思这里说错了，应该说在启动参数设置为yaffs加载的时候，无论文件系统中的数据是否正确，内核都会启动yaffs来加载文件系统。
不过就算启动参数设置为nfs，如果yaffs驱动移植成功的话都会显示yaffs Nov 11 2011 20:57:33 Installing. 之类的信息的，个人认为楼主在移植yaffs文件系统驱动的时候应该没移植成功。 wuweidong 发表于 2012-5-1 21:18 static/image/common/back.gif

按着天嵌的手册yaffs2应该烧写在0x000000500000-0x000010000000 上吧！地址我是设置对了，至于uboot的bootargs的设置，好像我没有注意着个选项，我再好好看看，谢谢！ 本帖最后由 ~悟`~念~ 于 2012-5-2 21:35 编辑

首先先感谢楼主的解答，昨天晚上停电了，今天上了一早上的C#课。所以没有及时回复：
我的想法：
我用我的内核编译zImage.bin 和我自己制作的yaffs2文件系统挂载的时候会出现我上面图中的第一个错误，也就是没有挂载上yaffs2文件，用天嵌公司的内核镜像和我自己制作的yaffs2文件系统挂载的时候，好似能挂载上了，所以说我的yaffs2文件系统应该是没有大错的，但出现我上面图中的第二个错误。第二个错误：Failed to execute /linuxrc.Attempting defaults...
我上网翻了很多资料也按着做了，还是这个错误。
由于上面的对比 我认为是我的yaffs2系统在内核上添加的驱动程序不够，所以我又再三检查了一下，后来重新编译，我这除了手册上的红字部分改了之外，看着黑字也完全改了一遍，再次烧录后只出现第二个错误（自己的内核文件zImage.bin和自己的yaffs2文件系统），现在依旧在实验当中。。。。。。
因为论坛上的楼主们都说会有开发板重启的现象，而我的为什么没有啊？

这个时候你可以尝试烧入你自己做的内核和天嵌的文件系统，看看能否成功进入控制台。如果能进入控制台的话说明你的内核应该成功移植了yaffs文件系统驱动了，这个时候再慢慢去找你自己做的文件系统中有什么问题。如果用的是天嵌的内核并成功进入控制台的话，由于天嵌的内核中已经移植了看门狗驱动，很多人自己做的文件系统中没设置喂狗程序就会自动重启了。 guoke25 发表于 2012-5-2 15:02 static/image/common/back.gif

我检查了n遍还是那个问题，后来我把原先的都备份了，自己又重新移植了一遍yaffs2文件系统，后来一次性成功编译了，呵呵！
如图所示，但是我看到我的yaffs2就打印出两行，这个是否会影响其它项啊？

谢谢，重新移植了一遍，已经移植成功了！ YEAH,我遇到的问题跟你的差不多，但我用TQ的内核配自已的YAFFS2正常可以出现控制台。郁闷中。。。。 本帖最后由 woada 于 2012-6-27 23:55 编辑
我的， 进不了控制台，郁闷啊。
tq2440，3.5屏，linux-2.6.30.4_20100531
用的是天嵌的工具链，linux代码是网上下的，参考的是手册一步步做的，一开始也出mount 错误，后来直接用天嵌代码中的yaffs2拷贝过来，但又出来“can't open /dev/tq2440_serial0: No such file or directory
”一直打印这个，无法进入控制台，高手帮忙分析下啊，先谢谢啦！
