移植linux-2.6.31.1文件系统挂载不上，help....

前两天从网上下载的最新linux-2.6.36.1,想试试往mini2440上面移植，本人新手，第一次移植，移植中有些问题，也参照网上各位先烈的资料，终于一点一点克服，最后内核终于能起来了，但是始终挂载不上文件系统，我下载了mini2440自带的root_mizi.img文件系统，好像也不行，实在郁闷...这里寻求各位高手帮助～

1.板子分区信息如下:

Enter your selection: q
Supervivi> part show
Number of partitions: 5
name            :    offset        size        flag
------------------------------------------------------------
vivi            :    0x00000000    0x00028000    0
eboot           :    0x00028000    0x00018000    0
param           :    0x00040000    0x00010000    0
kernel          :    0x00050000    0x00200000    0
root            :    0x00250000    0x03dac000    0

2.  参考网上资料，修改内核

static struct mtd_partition mini2440_default_nand_part[] = {
        [0] = {
                .name   = "supervivi", /*这里是 bootloader 所在的分区，可以放置 u-boot, supervivi 等内容，对应/dev/mtdblock0*/
                .offset = 0,           /*0~256K*/
                .size   = 0x00040000,  /*256K空间*/
        },
        [1] = {
                .name   = "param", /*这里是supervivi的参数区，其实也属于bootloader的一部分，如果u-boot 比较大，可以把此区域覆盖掉，不会影响系统启动，对应/dev/mtdblock1 */
                .offset = 0x00040000,  /*256K~320K*/
                .size   = 0x00010000,  /*64K空间*/
        },
        [2] = {
                .name   = "Kernel",// ;内核所在的分区，大小为 5M，足够放下大部分自己定制的巨型内核了，比如内核使用了更大的Linux Logo图片等，对应/dev/mtdblock2
                .offset = 0x00050000,  /*320K~2.32M*/
                .size   = 0x00200000,  /*2M空间*/
        },
        [3] = {
                .name   = "root", //;文件系统分区，友善之臂主要用来存放yaffs2 文件系统内容，对应/dev/mtdblock3
                .offset = 0x00250000, /*2.32M~66.32M*/
                .size   = 0x03dac000,
        },
        [4] = {
                .name   = "nand", //;此区域代表了整片的nand flash，主要是预留使用，比如以后可以通过应用程序访问读取/dev/mtdblock4就能实现备份整片nand flash了。
                .offset = 0x00000000, /*6.384M～7.384M*/
                .size   = 1024 * 1024 * 1024, /*1M空间*/
        }
};

3.修改启动命令为:  noinitrd root=/dev/mtdblock3 init=/linuxrc console=ttySAC0


4.我是直接下载到RAM中运行，启动信息如下:
Copy linux kernel from 0x00050000 to 0x30008000, size = 0x00200000 ... done
zImage magic = 0x016f2818
Setup linux parameters at 0x30000100
linux command line is: "noinitrd root=/dev/mtdblock2 init=/linuxrc console=ttySAC0"  ---------------》》这里不知道为什么命令为root=/dev/mtdblock2，我改为3了，下面可以看到

在网上查了很多相关的资料，还是不行，寻找高人帮助～～～





  

我也没挂上文件系统。

耽搁了两天，今天晚上准备再继续研究一下

问题解决了，这里将编译过程中遇到的问题和在网上搜索到的一些解决方法写在这里，也算是这段时间学习的小小总结，希望能给遇到同样问题的初学者一点帮助：
记录:
    1.下载linux-2.6.36.1.tar.bz2
      问题:tar -zxvf 解压压缩文件出现问题，无法识别.
      解决:1.通过file linux-2.6.36.1.tar.bz2 查看压缩格式
          2.通过命令 bzip2 -d linux-2.6.36.1.tar.bz2解压
          3.再通过tar xvf linux-2.6.36.1.tar解压，不能使用
            tar zxvf linux-2.6.22.6.tar解压
          4.上面也可以通过一条指令bzip2 -dc linux-2.6.XX.tar.bz2 | tar xvf -
            其中XX为内核压缩包文件名

    2.下载patch-2.6.36.1.bz2补丁文件
      1.解压 bzip2 -d patch-2.6.36.1.bz2
      2.cd linux-2.6.36.1/
      3.patch -p1 < ../patch-2.6.36.1

    3.先编译看下内核有没有问题，运行make命令出现下面的错误:
      问题:drivers/input/touchscreen/eeti_ts.c:65: 错误： 隐式声明函数‘irq_to_gpio’
      解决:重新make menuconfig，将driver中的输入设备->触摸设备中,将EETI选项不选，保存退出后，重新make.

    4.将编译成功的内核zImage下载到板子中，出现如下问题：
      问题:NOW, Booting Linux......
          Uncompressing Linux... done, booting the kernel.
          然后没有反应....
      解决:1.Device Drivers--->Character devices--->Serial drivers
            下，选择：Samsung SoC serial support
                    Support for console on Samsung SoC serial port
                    Samsung S3C2440/S3C2442 Serial port support
          2.发现对应选项在Device Drivers->Character devices->Serial drivers中
            一看,原来根本就没有加载Samsung SoC serial support , 选成静态编译之后又出现了
            Support for console on Samsung SoC serial port ,就是它了,选上, 退出的时候顺便把
            Kernel low-level debugging functions给取消了否则我们设置的printk会自行输出,就不知道ttySAC有没有加载成功了
          3.最后发现原来时内核编译时需要传入一个启动命令:noinitrd root=/dev/mtdblock2 init=/linuxrc console=ttySAC0,
            make menuconfig -> Boot options -> 第三行添加上面的启动命令，保存退出，启动成功～

    5.启动过程中，出现问题:
      问题:Unable to handle kernel NULL pointer dereference at virtual address 00000000
          pgd = c0004000
          [00000000] *pgd=00000000
          Internal error: Oops: 80000005 [#1]
          last sysfs file:
          Modules linked in:
          CPU: 0    Not tainted  (2.6.36.1 #20)
          PC is at 0x0
          LR is at s3c_gpio_setpull+0x80/0x8c
      解决:参考网址:http://blog.csdn.net/ExclusivePig/archive/2010/10/24/5961869.aspx
          将static inline int s3c_gpio_do_setpull函数修改为以下内容:
          static inline int s3c_gpio_do_setpull(struct s3c_gpio_chip *chip,
                      unsigned int off, s3c_gpio_pull_t pull)
          {
              if(NULL != chip->config->set_pull)
                  return (chip->config->set_pull)(chip, off, pull);
              else
                  return EINVAL;
          }

     6.内核终于启动起来了，但是接着又出现了下面的问题：
       问题:List of all partitions:
           1f00             256 mtdblock0 (driver?)
           1f01              64 mtdblock1 (driver?)
           1f02            2048 mtdblock2 (driver?)
           1f03           63152 mtdblock3 (driver?)
           1f04           65536 mtdblock4 (driver?)
           No filesystem could mount root, tried:  cramfs
           Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(31,2)
       解决:原来是没有添加YAFFS2文件系统，从网上下载，给内核打上补丁，重新make menuconfig，在file system中选择YAFFS2,重新make.
           打补丁如下:./patch-ker.sh c /work/system/linux-2.6.36.1

      7.编译出现问题，最新内核去掉了一些函数，和改变了一些函数的名字，致使YAFFS2在编译过程中出现错误。
        解决:请参考：http://www.linuxhq.com/kernel/v2.6/36-rc1/fs/attr.c

      8.再次下载编译好的内核，运行出现下面问题:
        问题:yaffs: dev is 32505858 name is "mtdblock2"
            yaffs: passed flags ""
            yaffs: Attempting MTD mount on 31.2, "mtdblock2"
            yaffs_read_super: isCheckpointed 0
            VFS: Mounted root (yaffs filesystem) readonly on device 31:2.
            devtmpfs: error mounting -2
            Freeing init memory: 120K
            Failed to execute /linuxrc.  Attempting defaults...
            Kernel panic - not syncing: No init found.  Try passing init= option to kernel.
        解决:1.启动命令有问题，根据查看分区信息(supervivi:part show)得知root分区在mtdblock3上，不是在2上
              修改为:noinitrd root=/dev/mtdblock3 init=/linuxrc console=ttySAC0
            2.问题依旧，重新make menuconfig,并对比友善之臂提供的mini2440源代码配置，重新选择，
              Device Driver ->Generic Driver Options ->(取消)devtmpfs: error mounting -2被解决了，
              但是依然无法启动继续查看。
            3.系统在启动过程中出现了很多yaffs: block 456 is marked bad，block 457 is bad这样的错误，越来越多，通过网上搜寻找到解决办法:
              我用的是板子自带的supervivi,使用命令bon part 0，就起到格式化整个Nand Flash芯片的作用，假坏块自然就化为乌有了。随后问题就柳暗花明。
            4.将mini2440自带的文件系统重新烧如板子，用mini2440自带的内核文件启动，正常，说明文件系统没有问题，将自己编译的内核下载进去，依然无法启动，
            5.添加一些内核输出信息，终于发现内核在:search_binary_handler()函数中的fn(bprm, regs)函数后，执行失败了。非常郁闷...
            6.文件系统没有问题，显然还是内核编译有问题，然后通过网上查找说是load_elf_binary执行有问题，可能是加载文件系统的文件时不识别文件格式，于是
              重新make menuconfig最后发现原来是要将General setup  --->Choose SLAB allocator --->选上SLAB,不要选择SLUB。重新make
              哈哈，终于启动成功了，再次查看了一下mini2440板子上的配置，发现它的内核里选择的是SLUB，而我用的内核选上SLUB反而启动不起来，不知道什么原因，
              希望知道的人能回答一下，下面是系统启动信息:
