2008年购买了QQ2440，后来出去工作了，2440压箱子底压了两年，现在拿出来想弄弄qtopia,可是一查友善的资料已经出到了ARM11的板子了，内核以及qtopia的支持根文件映像也不知升级了多少次了，在此先恭喜友善能做的这么快。后来在友善网上下得了MINI2440的整个光盘内容，希望通过将mini2440光盘中的kernel2.6.32和root下载到QQ2440上使使。不过一路上遇到了超级多的问题，最后总算是可以将kernel和root下载进去了，可是刚开始开启QQ2440时程序跑不起来，后来得到了版主和一些热心朋友的帮助，最终通过一些修改终于可以以NOFLASH启动方式跑起来了。不过还存在几个驱动不匹配的问题。我用的是N35的屏，2008年QQ2440光盘中的supervivi，最近刚发布的MINI2440光盘中的kernel （linux2.6.32）以及最新的root。
下面将我一步一步的过程记录如下，希望给同样使用着QQ240板子的初级学者一点帮助，高手就莫笑话我了，另外网络驱动和USB驱动的问题请高手看出什么问题后给点帮助和建议。
步骤一 直接利用QQ2440中的supervivi（2008年的版本）烧写MINI2440光盘中的内核和根文件系统到QQ2440nandflash
1.1 出现问题 ： 在烧写zimageN35时出现了被烧写的文件大小大于分区大小，不让烧写
1.2 解决思路 ：我猜想应该是老版本的supervivi中对于内核的分区太小了，于是我决定先升级SUPERVIVI到最新版本
步骤二 利用H-JTAG升级supervivi64M到norflash，按照mini2440光盘中的介绍升级supervivi
2.1 出现问题 ：supervivi烧写进入了K9F1208芯片（由于我是笔记菜的菜鸟，此时还不知道该芯片是NANDFLASH），
但是以NOFLASH方式启动QQ2440时串口输出的还是以前的信息。
2.2 解决思路 ：我猜测是不是烧写的地方不对（因为H-JTAG的烧写过程是对的，表示程序确实被烧到某个地方了），
然后经过SEA大哥一点播发现K9F1208为nandflash芯片， 我说难怪会看到有64M的空间的，后来选择对了
芯片（QQ2440为AM29LV160DB），烧写进去后串口输出果然跟mini2440资料上一样了。

步骤三 利用新的supervivi64M开始下载zimageN35
3.1 出现问题：按照MINI2440光盘上的方法（noflash方式启动然后按“F”）进行分区，可是打印出的信息一直为失败
并且USB好像出了问题，DNW不能正常下载东东了，安装驱动后提示没找到USB设备，重新拔插也没
让我安装驱动，windows也没有噔噔、噔噔的硬件拔插呻吟声了。
3.2 解决思路：这个我还没有什么解决思路，只好先放在一边了。
3.3 打印信息：
q] Goto shell of vivi
Version: 0945-12
Enter your selection: f
...................................................................................................................................................
......................................................................................................................................................
.................................................................................................................... ... failed
3.4 我利用part show看了看硬件分区，不知道为什么，确实是改变了，分区如下：
Enter your selection: q
Supervivi> part show
Number of partitions: 4
name : offset size flag
------------------------------------------------------------
vivi : 0x00000000 0x00040000 0
param : 0x00040000 0x00020000 0
kernel : 0x00060000 0x00500000 0
root : 0x00560000 0x03a9c000 0
Supervivi>
以前的vivi分区只有0X00020000的，现在变为了0x00040000，看来确实是变大了。但是DNW用不了了
没办法下载，只好考虑把以前的VIVI换回来。
步骤四 重新把2008年的supervivi烧写到noflash中，USB好了
4.1 重新又把08的VIVI烧了进去，然后利用part add 和part del手动分区，将分区分的跟上面一摸一样。
4.2 出现问题 ：烧写kernel以及root确实没什么问题了，可以烧成功了，nandflash中的vivi下载为新的supervivi64M
kernel烧写的是mini2440光盘中的 zimageN35,root烧写的是mini2440光盘中的root_qtopia-64M.img。不过启动是跑不过kernel。
4.打印信息如下：
Enter your selection: b
Copy linux kernel from 0x00060000 to 0x30008000, size = 0x00500000 ... done
zImage magic = 0x016f2818
Setup linux parameters at 0x30000100
linux command line is: "noinitrd root=/dev/mtdblock2 init=/linuxrc console=ttySAC0"
MACH_TYPE = 782
NOW, Booting Linux......
Uncompressing Linux.......................................................................... ......................................................................................... done, booting the kernel.
4.4 解决思路 ： 到了MACH_TYPE这就过去了，估计是MACH_TYPE的问题了，于是找了找资料，发现MINI2440的mach_type 为1999
步骤五 改写了mach_type为1999 ，确实跑过了kernel，大喜
5.1 出现问题 ： 跑到了根文件系统那过不去了
5.2 打印信息 ：
Enter your selection: b
Copy linux kernel from 0x00060000 to 0x30008000, size = 0x00500000 ... done

5.3 解决思路：是不是 ROOT下载的地址和vivi启动的地址没对上产生的这个问题，不过由于小弟比较菜 这个问题实在不知道怎么解决了。 步骤六 根据楼主的提示，的确是vivi中的分区表与kernel中启动地址没对上，更改启动配置的地方 6.1 更改方法 noflash方式启动 ，按键“q”
然后在命令输入行键入> param set linux_cmd_line "console=ttySAC0 root=/dev/mtdblock3"
> boot
可以启动了，跑起来了。
6.2 遇到问题 ：虽然root跑了起来，但是可以发现网络以及USB都不能正常使用了,并且不能以NANDFLASH的方式跑，因为没有supervivi的源码，
只能通过norflash方式修改启动时的root对应分区才能跑起来。
6.3 解决思路 ：修改内核，自己做一个适合QQ2440的linux-2.6.32
步骤7 制作适合QQ2440的内核linux-2.6.32，为了让QQ2440以nandflash方式启动是跑起以yaff2方式的ROOT，必须修改内核的两处地方然后重新编译（还没解决驱动的问题），第一处是在内核配置文件中修改nandflash的分区数组中的root所在的位置，第二处是加入对yaff2文件系统的支持。 7.1 在内核配置文件中修改nandflash的分区数组中的root所在的位置： a将mini2440光盘中的linux文件夹中的linux-2.6.32.2-mini2440-20100609.tar.gz文件拷贝到linux系统中
b 解压缩linux-2.6.32.2-mini2440-20100609.tar.gz，shell命令行# tar xzvf linux-2.6.32.2-mini2440- 20100609.tar.gz -C /opt/FriendlyARM/QQ2440/kernel c # cd /opt/FriendlyARM/QQ2440/kernel/linux2.6.32/arch/arm/mach-s3c2440/ d#gedit mach-mini2440.c e 将其中分区数组改成如下情况 static struct mtd_partition friendly_arm_default_nand_part[] = {
[0] = {
.name = "supervivi",
.size = 0x00040000,
.offset = 0,
},
[1] = {
.name = "param",
.offset = 0x00040000,
.size = 0x00020000,
},
[3] = {
.name = "Kernel",
.offset = 0x00060000,
.size = 0x00500000,
},
[2] = {
.name = "root",
.offset = 0x00560000,
.size = 1024 * 1024 * 1024, //
},
[4] = {
.name = "nand",
.offset = 0x00000000,
.size = 1024 * 1024 * 1024, //
}
};
f 保存退出 7.2 修改menuconfig中的项目，使得kernel支持yaff2文件系统 a 进入刚才加压缩的内核的根目录，也就是linux2.6.32下，使用 make mini2440-defconfig b #make menuconfig c进入file systems-> miscellaneous filesystems d 找到yaff2该项，并按空格建选住 e 退出并保存 7.3 产生内核 a a 进入刚才加压缩的内核的根目录，也就是linux2.6.32下，使用 make mini2440-defconfig b # make zImage 等待一会会在/arch/arm/boot中生成zImage。将该zImage拷贝到windows下。 7.4 利用supervivi将该内核文件烧写到nandflash中，根文件系统还是烧写mini2440光盘中的最新文件系统。 7.5 nandflash方式启动QQ2440,QQ2440可以跑起来了，不过现在触摸屏什么的都不能用了，驱动没加入。 步骤8 制作适合QQ2440的内核驱动(一)--------借助友善的配置文件修改 8.1 直接使用友善做好的内核配置config_mini2440_n35(因为我的QQ2440是N35的屏幕) a 按照7.1 先修改好MACH-MINI2440,C文件 b
#cp config_mini2440_n35 .config c make menucofig 先进去逛逛，看看能否开启该编译选择框 d make zImage e 拷贝。。/arch/arm/boot中的zImage到windows下，然后烧写到QQ2440 8.2 以noflash方式启动，直接按b,可以看到启动正常了，并且之前的驱动都还在里头（触摸屏可以用 ，音乐可以听，串口也是好的等） 8.3 以nandflash方式启动，同样可以启动的了。步骤九 制作适合QQ2440的内核驱动(二)-------移植网卡驱动总结：碰到了主要两个问题：1新的supervivi烧写到QQ24440后，QQ2440的USB下载功能没了 2,利用旧的supervivi手动分区后下载新的内核以及ROOT，可以跑起来了， 不过网络功能和USB功能没有。 对该文章有兴趣的朋友可以邮箱联系，共同探讨。本人邮箱：[url=mailto:litie86222@163.com]
