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! Eep. Child "calibration" (ino #464) of dir ino #461 doesn't exist! Eep. Child "coredsp_driver.ko" (ino #939) of dir ino #336 doesn't exist! Inode #1307 was a directory with children - removing those too... Inode #564 was a directory with children - removing those too... Inode #565 was a directory with children - removing those too... Inode #1112 was a directory with children - removing those too... Inode #1115 was a directory with children - removing those too... Inode #1118 was a directory with children - removing those too... Inode #1123 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?
Yes I created jffs2 filesytem using mkfs.jffs2 prior to mounting and then I am over-writing some of the binaries. In case of overwrites from NFS after reboot I see the above errors & the binaries/directories gets deleted from the jffs2 partition.

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.

and file system is created using fallowing command.. mkfs.jffs2 -r RFS_NEW/ -e 0x20000 -o /tftpboot/jffs2_img -bI am recalling playing with the options upper also cured the jffs2 warnings
(not as many as yours but anyway) The other options I am wondering about, -c, --cleanmarker=SIZE Size of cleanmarker (default 12) -n, --no-cleanmarkers Don't add a cleanmarker to every eraseblock cleanmaker size will it help the cause?
