Kernel2.6+Nand/JFFS2 released.

CoryXie · 发表于 2005-10-8 10:03:58

很高兴在这里和大家分享成功的喜悦!
1.小弟在Lumit4510板子上移植了uClinux with Linux Kernel 2.6.9,当然,大部分工作都是用的ESPD版的，但是在这个版本基础上完全更换了MTD子系统和JFFS2文件系统，使用了最新的MTD CVS版本。前几天新内核就可以跑了，但是
NAND Flash 上的JFFS2文件系统却有问题。换了MTD子系统和JFFS2文件系统后，就可以跑NAND Flash 上的JFFS2文件系统了。但是换得过程中遇到许多问题，修改了老半天，可以说现在的源代码已经和原来的代码有很大差别了。
2.为了能够访问Lumit4510板子上的NAND FLASH设备，更新了一下小弟前段时间移植的U-boot for lumit4510,添加了对外部I/O的访问控制。
3.我准备把所有的移植源文件都上传到公用空间上去，但是不知道空间够不够。这里先贴一些控制台信息,基本上是我移植完后将ROOTFS从NFS方式切换成JFFS2方式的整个过程。看大家有没有兴趣，有兴趣的话，给点鼓励啊！！呵呵，浪费空间了！！！

159.226.40.150 上还有 16G 的空间，足够放没问题。

Cory 的进展很快啊，鼓励鼓励！

说明：
1。整个过程分成3个阶段，第一阶段使用ROMFS方式；第二阶段使用NFS方式；第三阶段就是JFFS2方式了。第一阶段主要是看能不能用ESPD版本的移植，发现该版本如果直接编译，将会有很多问题，启动后Exception很多，马上kernel panic.最后才发现，/etc/rc文件中最后一项dhcp相关一项出问题，注释掉就可以运行。当然，编译也不是很简单，需要换新的交叉编译环境arm-uclinux-gcc,是gcc 3.4版本，也要修改一些文件。关于编译，我另辟小节详述。第二阶段，是用NFS方式作为根文件系统，但是还使用原来romfs目录下面的文件，只是dev子目录下面的要大换血。此外，使内核能够支持NFS 方式作为ROOTFS还需要一些附加编译选项。这一点，也在别的小节叙述。第三阶段，是用JFFS2作为根文件系统，这要求JFFS2文件系统已经放到/dev/mtd0中。下面的控制台信息会显示如何完成这一步。当然，这也很简略，我想有时间还是把这个整个过程写一篇文档比较好。
2。u-boot可以传递内核启动参数，使用u-boot命令setenv，saveenv可以将启动参数保存历来。对于第一阶段，启动参数用：
[code:1]
lumit4510 #setenv bootargs root=/dev/ram0 rw keepinitrd
lumit4510 #saveenv
[/code:1]
对于第二阶段，启动参数用
[code:1]
lumit4510 #setenv bootargs=root=/dev/nfs rw nfsroot=192.168.1.2:/root/lumit/src/uClinux/2.6/uClinux-dist/romfs ip=192.168.1.5:::::eth0:any
lumit4510 #saveenv
[/code:1]
对于第三阶段，启动参数用
[code:1]
lumit4510 #setenvbootargs=root=/dev/mtdblock0 rw rootfstype=jffs2
lumit4510 #saveenv
[/code:1]

1。直接用NFS方式试一下，这次我把JFFS2文件系统已经写到NAND Flash
中了。关于如何写进去，待会我再写一次做演示，可以照着做。这次是检验一切正常可用。

让我们看一下16MB的NAND Flash是怎么被分区的。对于NAND FLASH的驱动代码，我放在drivers/mtd/nand/lumit4510_mtd.c中。
[code:1]
/> cat /proc/mtd
dev: size erasesize  name
mtd0: 00800000 00004000 "LUMIT4510 flash partition A"
mtd1: 00800000 00004000 "LUMIT4510 flash partition B"
[/code:1]
其实从其启动信息中您也可以看到：
[code:1]
Creating 2 MTD partitions on "NAND 16MiB 3,3V 8-bit":
0x00000000-0x00800000 : "LUMIT4510 flash partition A"
mtd: Giving out device 0 to LUMIT4510 flash partition A
0x00800000-0x01000000 : "LUMIT4510 flash partition B"
mtd: Giving out device 1 to LUMIT4510 flash partition B
[/code:1]
接着，如前所述，我已经将JFFS2文件系统写到/dev/mtd0中，所以我来看看
能不能mount到目前用NFS方式的根文件系统的/mnt下面。
[code:1]
/> mount -t jffs2 /dev/mtdblock0 /mnt
Empty flash at 0x000b9070 ends at 0x000b9200[注意，这里的信息好像并不重要]
/> cd /mnt
/mnt> ls
bin
dev
etc
home
lib
mnt
proc
sbin
tmp
usr
var
/mnt>
[/code:1]
看来是没有问题的。

CoryXie · 发表于 2005-10-8 11:01:41

既然上面的操作都能正常进行，那我就再来写一次。注意，这时，我还是用NFS方式在作根文件系统，所以，我可以在PC机上用mkfs.jffs2工具来讲uClinux-dist/romfs这个目录整个生成JFFS2文件系统映像。方法如下：
[code:1]
#cd uClinux-dist
#mkfs.jffs2 -l -n --pagesize=0x200 --eraseblock=0x4000 --pad=0x30000 -d romfs -o jffs2.img
注意，上面的命令是在PC机上运行。当然，我也编译了在lumit4510上运行的mkfs.jffs2。
[/code:1]
好了，来写一次。
当然，写之前，先用flash_eraseall命令来erase掉/dev/mtd0.这个flash_eraseall可是换了MTD-utils之后才有的命令哦，它比以前的eraseall可是好多了，能顺带格式化FLASH,使得可以支持JFFS2和YAFFS(我的下一个目标就是他了)。
[code:1]
flash_eraseall -j /dev/mtd0

我们可以重新用NFS作为根文件系统的方式启动内核，然后再看看我们新写入的JFFS2文件系统能不能mount上.
[code:1]
/> mount -t jffs2 /dev/mtdblock0 /mnt
/> cd /mnt
/mnt> ls
bin
dev
etc
home
lib
mnt
proc
sbin
tmp
usr
var
/mnt>
[/code:1]
没问题。所以，我们下一步就可以切换成直接将内核的引导参数改成JFFS2方式。
reset一下板子之后，进入u-boot的命令行模式：
[code:1]
lumit4510 # setenv bootargs root=/dev/mtdblock0 rw rootfstype=jffs2
lumit4510 # save
Saving Environment to Flash...
Un-Protected 1 sectors
Erasing Flash... done
Erased 1 sectors
Writing to Flash... done
Protected 1 sectors
lumit4510 #
[/code:1]
这样，我们重新tftp，bootm内核时，就可以让内核从NAND Flash中的加载JFFS2文件系统了。我们的文件系统放在/dev/mtd0,但是引导参数中却要写成/dev/mtdblock0，这是NAND FLASH作为字符设备和块设备的区别，别处说。

可见，我先用u-boot将内核用tftp下载到内存的0x100000位置，然后用u-boot将这个内核从0x100000处拷贝到0x1030000到0x1200000之间。
我们的整个存储器空间分配是这样的：（u-boot在启动时已经remap过lumit4510的存储器空间，关于这一点，有时间我叙述一下u-boot的remap过程，还是很精巧的！！使用片内的8KB SRAM来完成的。）
0x00000000---0x01000000,16MB SDRAM 内存。
0x01000000---0x01200000,2MB Nor Flash。
所以，我上面将内核从0x100000处拷贝到0x1030000到0x1200000之间，实际上就是把内核放到了Nor Flash中去了。当然，本来u-boot是放在Nor Flash的0x00000000---0x00030000之间的，经过remap之后就是在0x01000000---0x1030000之间了（这是说存放u-boot的地方，只是u-boot并不在这个区间运行，而是在
U-Boot code: 00ED0000 -> 00EE8434  BSS: -> 00EF2688
之间运行。因为我将TEXT_ADDR该成了 00ED0000。这是u-boot的话了，别处详述。

好了，这次我们不用人工干预，reset板子之后让他自己运行，当从7，6，5，4，3，2，1，0后，系统自动运行了。

已经将所有相关文件上传到
http://159.226.40.150/ftp_root/u ... e/NewKernelPorting/
可以到相关目录下载.由于时间限制,还没有写出完整的文档,以后慢慢补齐.
在src目录下面是我用到的一些文件,在tools下面是工具,在release下面是已经移植
编译过的uClinux-dist,可以致用这个压缩包和工具来实验.
src下面的文件占用了很多空间,如果必要,版主可以删去,我放到那里主要是为了方便
到别的网站去下,很慢,我下载uClinux-dist-20041215.tar.bz2用了整整一天时间.

我用你的release编译后，启动时出现如下错误，大侠能否帮忙解决一下，几种环境变量都试过，都不行，这是第一种

大侠，你在用kernel2.6+jffs2时，telnetd能否使用阿？我编译的内核，telnetd不能启动，显示all net prot in use!不知道怎么改
