ah ok. i should make a small break to go into the forest and reset my brain.

my kernel doesn't start; the mtd partitioning is bad.
Please, can you answer another question? I change the mtd-partitioning in kernel 2.6.24 to default in 2.6.13 to use the 2.6.24 with supervivi-default-parameter. It is correct? Must i change the bootarg? e.g. rootfstype etc.?

It should be OK if you tell MTD to use hard coded default partition table in 2.6.13 and this table should be consistent with the one in supervivi. However, I'm not sure if this feature, i.e. use hard coded partition table, is available in NAND controller driver in your ported 2.6.24 kernel.
The rootfs type setting depends on which rootfs image you use (yaffs or jffs2?)

Would you please paste complete kernel booting log?

Here's MTD partition table for QQ2440 hard coded in 2.6.13 kernel. It  is consistent with supervivi. FYR.


static int chip0_map[] = { 0 };
struct mtd_partition bit_default_nand_part[] = {
[0] = {
.name = "bootloader",
.offset = 0x00000000,
.size = 0x00030000,
},
[1] = {
.name = "kernel",
.offset = 0x00050000,
.size = 0x00200000,
},
[2] = {
.name = "root",
.offset = 0x00250000,
.size = 0x03dac000,
}
};

/* the bit has 1 selectable slots for nand-flash, the three
* on-board chip areas, as well as the external SmartMedia
* slot.
*
* Note, there is no current hot-plug support for the SmartMedia
* socket.
*/

static struct s3c2410_nand_set bit_nand_sets[] = {
    [0] = {
        .name        = "chip0",
        .nr_chips    = 1,
        .nr_map        = chip0_map,
        .nr_partitions    = ARRAY_SIZE(bit_default_nand_part),
        .partitions    = bit_default_nand_part
    },
};


static struct s3c2410_platform_nand bit_nand_info = {
              ...
    .nr_sets    = ARRAY_SIZE(bit_nand_sets),
    .sets        = bit_nand_sets,
};

However, the rootfs cannot be mounted even if you use the correct partition table. Because yaffs support in this 2.6.24 kernel is not usable.
I sugguest you use customized u-boot and jffs2 rootfs image instead.

Hello,

ok. now i have a u-boot bootloader.
In u-boot i can write the kernel in nandflash; the kernel starts (same log as yesterday). Then i try the same rootfs from cd-rom (2.6.13), extract on pc and make a jffs2 image with mkfs.jffs2-script. If i write the jffs2 rootfs into nandflash at 0x634000 the system crashed; damaged kernel etc? So confused :-( i only want a working system; and i don't think, that i can build a working rootfs for myself

Would you please provide steps you create and flash the jffs2 image and the kernel booting log?

Hello Kasim,

sorry - it looks like an other problem.
At first; i use your uboot (without lcd support because size of uboot) and your kernel.

Now, i write uboot into nand-flash. After board-reset the uboot-console is active via serial line.
Then i write the kernel (uimage) via mmc card at the device.

with following commands:
mmcinit
fatload mmc 0:0 0x32000000 uimage
nand write.jffs2 0x32000000 0x34000 $filesize

after reset the board, the kernel start. Now, i switch off the board, unplug the batterie and switch the board on the u-boot write an error:

incorrect device type in kernel
'kernel' is not a number
## Booting image at 32000000 ...
Bad Magic Number
QQ2440 #

for me; it looks like, that the kernel will not be copied from nand-flash into ram.

next stepp.
i can't set env-variables in uboot / after power-down the variables have the default-value!
If i use in uboot <dynpart> and then <bootd> the kernel will be load out of nand-flash (yeah :-) ).
Now, i write the root.bin which i create following:
extract <root_default.tgz> (from cd-rom).
create with mkfs.jffs2 (mtd-tools) the root.bin file (i use this way at various linux-systems - and it works fine).

here my log:
