JFFS2:CRC != calculated CRC

[Mark U]

Hi,

I'm trying JFFS2 as root file system on a MIPS MALTA board, the flash
device is Spansion S29GL256N. Linux kernel is 2.6.10. The User FS
partition in 16MB, but my JFSS2 image is < 4 MB. I'm getting the error
message only the FIRST PASS with the inux kernel.

This error is thrown only the _first_ _time_ I erase the flash
partition and flash the image to the partition. From next time booting
(without re-flashing the image) this error is not shown by the Kernel.
Each time I relash the partition with the _same_ _JFFS2_ image to the
same location in flash the locations shown in CRC error keeps
changing.

I tried '-p' option in the mkfs.jffs2 utility this error is not coming.

 -p, --pad[=SIZE]       Pad output to SIZE bytes with 0xFF. If SIZE is
                         not specified, the output is padded to the end of
                         the final erase block

Could anyone let me know why its giving the earler CRC error.
