Hi All,
I'm facing with the JFFS2/NAND stuff around AM1808 EVM (w sdk_5.03.02.00).
After having cross-compiled and installed MTD-utilities in my NFS-exported filesystem
I'm able to generate a JFFS2 image and store it in NAND's "rootfs" partition (/dev/mtdblock4).
Some warning messages appear during sector erase:
> flash_erase /dev/mtd4 0 0
Erasing 128 Kibyte @ 14aa0000 -- 65 % complete flash_erase: Skipping bad block at 14ac0000
Erasing 128 Kibyte @ 1f960000 -- 99 % complete flash_erase: Skipping bad block at 1f980000
flash_erase: Skipping bad block at 1f9a0000
flash_erase: Skipping bad block at 1f9c0000
flash_erase: Skipping bad block at 1f9e0000
Erasing 128 Kibyte @ 1f9e0000 -- 100 % complete
Anyway, I proceed with writing
> nandwrite -p /dev/mtd4 rootfs-base-summed.jffs2
Then I can reboot with success..
VFS: Mounted root (jffs2 filesystem) on device 31:4.
OK!
However, for production I think it could be more convenient to fill the NAND flash from u-boot.
And the problem arises when I try to store the same image from within u-boot:
# tftp c2000000 k5/rootfs-base-summed.jffs2
# nand erase.part rootfs
# nand write c2000000 rootfs ${filesize}
Also here, the following messages appear during sector erase:
NAND erase.part: device 0 offset 0x4c0000, size 0x1fb40000
Bad block table found at page 262080, version 0x01

Skipping bad block at 0x1ffe0000
Now try to boot..
Kernel panic - not syncing: No init found. Try passing init= option to kernel. See Linux Documentation/init.txt for guidance.
Can anyone help me?
