2.6.14移植到2410的问题

编译器arm-linux-gcc3.4.1 redhat9 s3c2410的平台

root.cramfs使用的是2.4.18的

也试过把ecc去掉（/drivers/mtd/nand/s3c2410.c）

但打印的错误还是一样的

wiserltz

why Kernel command line: noinitrd root=/dev/bon/2 init=/linuxrc console=ttySAC0 mac=00:01:5D:68:7A:0F

form the message:

0x00000000-0x00020000 : "vivi"
0x00020000-0x00030000 : "param"
0x00030000-0x00130000 : "kernel"
0x00130000-0x00430000 : "root"

root is on the mtdblock3

I think it shoud be "noinitrd root=/dev/mtdblock/3 init=/linuxrc console=ttySAC0"

By the way, what is the filesystem of your flash?

wiserltz

no way to use console=ttySAC0 in 2.4 kernel

klrfpaul

我也试过noinitrd root=/dev/mtdblock/3 init=/linuxrc console=ttySAC0
和 noinitrd root=/dev/mtdblock3 init=/linuxrc console=ttySAC0
不清楚是mtdblock3 还是mtdblock/3，所以都试了

还是不行

我用的root.cramfs,原来开发板（2.4.18内核）自带的，不知道能不能用在2.6的内核上？

我看了网上一些文章说是devfs的问题，2.6.14不支持devfs
不明白怎么回事？比较菜

wiserltz

Please post the following command's result:
vivi> bon part info
vivi> part show

And try to startup the board by NFS, mount the /dev/mtdX and check files there.

As for the unsupported devfs, please google "udev". Anyway I think it will not affect your system only
after you have loaded up the filesystem.

klrfpaul

谢谢你，我的这个问题解决了
就是在make menuconfig的时候加上cramfs支持就可以了
现在是出现这个问题：

NET: Registered protocol family 1
Reading data from NAND FLASH without ECC is not recommended
VFS: Mounted root (cramfs filesystem) readonly.
Freeing init memory: 88K
Warning: unable to open an initial console.

我想在root.cramfs的dev文件下下建立console节点，该怎么建立？

wiserltz

mknod /dev/console c 5 1

klrfpaul

我在pc上，建立的这个console节点
制成 root.cramfs后下载到2410上，没有反应
NET: Registered protocol family 1
Reading data from NAND FLASH without ECC is not recommended
VFS: Mounted root (cramfs filesystem) readonly.
Freeing init memory: 88K


/////Warning: unable to open an initial console. 这句警告没有了，但是就停在这个地方不走了

wiserltz

Check /etc/inittab & /etc/init.d/rcS

klrfpaul

一个周末过得，移植的东西都快忘光了

继续整

2.6.14的make menuconfig中没有devfs,要修改fs/kconfig,不知道和这个问题的关系大不大,先试试,到时bg

klrfpaul

搞定了，不过用的2.6.11
要容易一些
