So only for this reason, I cannot choose Cramfs for my
application deployment??? Then I have nearly no other
choice but use JFFS2 for deployment, which performance
couldn't compare with RAMDISK.It's a pity that RAMDISK
cannot update some info permanently. EXT2 seems not a
good idea for FLASH. I really feel puzzled with my
30MB application code deployment.

Thanks very much for your input!
