u-boot烧写yaffs2文件系统

分类： LINUX

u-boot烧写yaffs2文件系统
    以前移植的U-boot一直都支持Yaffs2文件系统的烧写，但是我一直都没有时间测试，其中的Bug也是网友发现后修正的。虽然现在又有新的UBI文件系统，但是UBI是在Linux2.6.28以后才被支持的，所以yaffs2还是需要的。前几天因为项目需要，我又试了一次Yaffs2的烧写引导，在这里记录下来，以备后用。

一、下载Yaffs2映像制作工具。
    mkyaffs2image就在yaffs2的源码包里：
    下载源码解压之后，在utils文件夹下的两个C文件就是yaffs和yaffs2文件映像制作工具，这里只将yaffs2了。512B/page的nand已经比较少了。
二、打上补丁
   为了正确制作Yaffs2文件系统映像，必须打上一下补丁：
文件:yaffs2_tekkaman_utils.patch.tar.bz2
大小:6KB
下载:下载


将补丁拷贝到Yaffs2源码目录下，并执行：

patch -p1 < ./yaffs2_tekkaman_utils.patch


补丁参考：
这个补丁增加了oob的两字节偏移和oob中ECC的产生。否则新的内核和yaffs2文件系统挂载会出错。

由于大小端的转换还有问题，所以被我去掉了。

三、编译
   直接在utils目录下“make”就可以了。

四、制作yaffs2映像文件

   制作命令很简单：

mkyaffs2image [dir] [image_file_name]


[dir]：是你要制做的文件系统内容所在的目录
[image_file_name] ： 是生成的映像名。

五、用U-boot烧入nand flash。
   添加yaffs2烧写功能的补丁是没有硬件依赖的，不单单在2440上可以用，应该可以说是在被Uboot支持的、可以操作Nand Flash中的oob的CPU上应该都可以用。我在别的CPU上已做了实验，没有问题。
   yaffs2烧写功能的补丁：
文件:u-boot_yaffs2img.patch.tar.bz2
大小:2KB
下载:下载

 要烧写的位置和内核分区有关。先擦除后烧写。

    产生“Partially written block 107 detected”的原因是你在写入nand flash后，没有等系统同步完，或者没有卸载系统就强行关机、重启，或系统宕机了。
   只要正常关机以后再启动就不会有这个提示了。

maroex: 打完补钉 在utils目录下make後 出现 mkyaffsimage.c:32:31: fatal error: yaffs_packedtags1.h 没有此一档案或目录 的错误.....
可能是由于版本更新的原因，这个补丁是2010年的。现在可能要重新研究下了。

问题解决了，原来是映像没做好，打了补丁之后，就可以了。谢谢！

aa03146: 为什么我用UBOOT烧写YAFFS时，刚开始时，NAND没有坏块，而烧写之后，NAND会打印出很多的坏块。到底是哪个环节出问题了哦？.....
你的烧写有问题，有两种可能：
1、uboot没有改好，时不小心吧oob的头两个字节清零了。如果那两个字节非0xffff，则nand中认为是坏块。请检查你的烧写程序。
2、烧写的映像没做好，oob头两个字节非0xffff，因为烧yaffs是会烧写oob的。请检查你的yaffs映像。
请用nand scrub命令擦除整个nand，修正你的错误之后，重新烧写。
