Hi david,
Thanx.I solved the Initial problem by giving the option 
-e in mkfs.jffs2 and the -p option.Now there is one more
message which is intesting
JFFS2: Erase block at 0x00200000 is not formatted. It will be erased
JFFS2: Erase block at 0x00240000 is not formatted. It will be erased
JFFS2: Erase block at 0x00280000 is not formatted. It will be erased
JFFS2: Erase block at 0x002c0000 is not formatted. It will be erased
JFFS2: Erase block at 0x00300000 is not formatted. It will be erased

I have only one JFFS2 partition and it starts 
from 0x800000. Why does JFFS2 scan these blocks?

Also how many blocks are allocated for gc in JFFS2 5 
or 4 ?
While loading the jffs2 image to the flash it erases 
only 2 MB but yet the df comamnd output shows that 
3184 1k blocks have been consumed. I am not able to 
understand how many sectors are for GC.Please help.
Thanx in advance,
Hari

You didn't tell mkfs.jffs2 the correct erase block size (-e 0x40000). Harmless.

Compaq bootldr bug. It seems to fill the end of the erase block in which 
the downloaded image ends with 0x1a. Use the '-p' option to mkfs.jffs2 to 
pad it out to the end of the erase block. Also mostly harmless.
