hi everyone,

I m using custom board similar to MPC8272ADS board...

1) For the first time it boots up properly in case if we overwrite any
existing binaries using nfs mounted file system on the board, after
rebooting it displays fallowing message...

Further such events for this erase block will not be printed
Eep. Child "null" (ino #1346) of dir ino #3 doesn't exist!
Eep. Child "autocomm" (ino #463) of dir ino #461 doesn't exist!

Inode #1307 was a directory with children - removing those too...

after this board boots up properly....but it not be having overwritten files

Have you created jffs2 file system on flash prior to mounting it?

2) while booting up for the first time itself it will display the falowing
message..

modprobe: FATAL: Could not load
/lib/modules/2.6.10_mvl401-8272ads/modules.dep: No such file or dire
ctory

but after this also board boots up properly

You are missing modules.dep, since haven't run depmod. Issue in from target and it will get cured.

3) when board is running properly in between it starts printing on console
repeatedly...

Do the proper MTD partitions setup, erase the partition and create jffs2 filesystem on it.
If after all those steps you're still getting output, that is prolly flakey flash.

Header CRC failed on REF_PRISTINE node at 0x00638a6c: Read 0xffffffff,
calculated 0x44660075
Node totlen on flash (0xffffffff) != totlen from node ref (0x00000254)
Header CRC failed on REF_PRISTINE node at 0x00638cc0: Read 0xffffffff,
calculated 0x44660075

[...]

 and 

file system is created using fallowing command..

mkfs.jffs2 -r RFS_NEW/ -e 0x20000 -o /tftpboot/jffs2_img -b

I am recalling playing with the options upper also cured the jffs2 warnings (not as many as yours but anyway)

do we need padding or not..?

I'd say that we do not. but it depends
