Hi all,

I am running u-b00t-1.6.6 on custom at91sam9263 board.

Are you sure it is u-boot-1.6.6? The latest u-boot in repository is
1.3.4.

Now i am able to boot, jffs2 filesystem with linux-2.6.20 kernel.
but the procedure i am using to burn is jffs2 is :

1)boot the linux kernel with ramdisk

2)erase the flash partition using $flasheraseall -j /dev/mtd1
3)writing the image using $nandwrite -p /dev/mtd1 rootfs.jffs2


You should be able to flash the jffs2 file sytem from u-boot.
No need to do it from linux.

The above procedure works well for me. But when i try writing the jffs2 
filesytem in uboot prompt its not booting (kernel panic).


In uboot i did this way:

1) tftp 2110 rootfs.jffs2
2)nand write.jffs2 2110 0x20 0x(hex add of displayed by tftp)


Which command is nand write.jffs2? Maybe you're using a version which
is modified by the board supplier. 
A normal way to flash it would be:

cp.b 2110 $(destiny_addr) $(filesize)

Cheers.

What is the write  of doing this?

I'm guessing he meant 1.1.6, which is quite old (and apparently old
enough to suffer l33tsp34k bitrot).

 Now i am able to boot, jffs2 filesystem with linux-2.6.20 kernel.

Especially since he's also using a kernel that is quite old. :-)

 1)boot the linux kernel with ramdisk

 No need to do it from linux.

I think that's the point, that it should work from u-boot but doesn't.

There's probably either something wrong with the u-boot NAND driver being
used, or the ECC layout doesn't match the kernel's.

 In uboot i did this way:
 
 1) tftp 2110 rootfs.jffs2
 2)nand write.jffs2 2110 0x20 0x(hex add of displayed by tftp)

It's a perfectly normal u-boot command.

 Maybe you're using a version which
 is modified by the board supplier.

 cp.b 2110 $(destiny_addr) $(filesize)

That's for NOR flash.  It does not work for NAND.
