yaffs文件系统移植

大家好，我在做到step12时遇到下面问题，请大家帮忙解决一下，谢谢！

你的启动输出信息中怎么没有看到关于yaffs2的信息？
配置内核的时候把支持yaffs2文件系统项选上，移植yaffs2系统。

不好意思，烧错文件了是这个结果：

就是我在yaffs文件系统移植时，出现了问题，帖中现象是我不知道错误原因，尝试编译64MB Nand Flash时的现象，发帖太急，把64MB的结果弄上去了，128MB以上的是这样的现象：

当时发帖时太急了，弄错了，请帮忙看一下！

你编译busybox 和内核都用什么版本的编译器？

6# embedsky_lxt


4.3.3 的编译器

5# dk56


从你打印出来的信息看，应该是你所烧的文件系统是64M的。与我的一模一样呀。你看一下！试一下。
如下是我开发板是256M但烧写64M的文件系统所报的错。


如果还不行的话，请把你做文件系统的步骤帖出来。如果你烧写的内核也是你但的话，你也帖出来。

8# wuchguang


对啊，是烧的64M的，当时发帖时没注意，你看一下三楼的，是我的256M的信息，麻烦你再帮我看一下，谢谢！

谢谢各位的帮助，我终于找到原因了，我习惯了从nor flash 启动的，只能烧写64M以下的，所以总是出现错误，不过还是没有完全解决问题，请大家帮忙看一下：

这是什么阿？乱码？

11# embedsky_lxt

我都无语了，这是在dnw软件中显示的，以前做文件系统移植时，超级终端总是显示乱码，而dnw和SecureCRT显示正常，我就一直用dnw软件，结果这次dnw软件也显示乱码了，我就再试一下超级终端，结果这次超级终端显示正常了，我现在是被折磨的一点脾气都没了，谢谢超级版主的回帖，以后有问题还需要您的帮助！

恩，有时候需要重启一下运用软件。
我不喜欢Windows 系统

Failed to execute /linuxrc.  Attempting defaults...
Kernel panic - not syncing: No init found.  Try passing init= option to kernel.

我的就这样子，下面没有其他内容了

14# hzxs533522


你是不是从nor flash 烧写的？要是的话就试着从nand flash 重新烧写！
