Hi all,
I am running u-b00t-1.6.6 on custom at91sam9263 board.
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
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 21100000 rootfs.jffs2
2)nand write.jffs2 21100000 0x200000 0x(hex add of displayed by tftp)
What is the write of doing this?

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

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

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 21100000 $(destiny_addr) $(filesize)
Cheers.

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

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

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.

It's a perfectly normal u-boot command.

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