[meta-freescale] ext2 vs ext3/4 over eMMC

[Mauro Ziliani]

Hi all.

I working on imx6dlsabresd clone board equiped with eMMC micron (4GB).

I try some boards with my final application. All boards are the equiped 
with same hardware (I hope).


Some board with ext2 kernel tells


EXT2-fs (mmblk2p2): error: ext2_lookup: delete inode referenced: 138049

EXT2-fs (mmblk2p2): error: ext2_lookup: delete inode referenced: 138050

and the file behind the inode gives Input/Output error.


If I format the mmcblk2p2 with ext3 or better with ext4 the lookup error 
no longer occurs (as I can see from some test)


Where is the problem?

Is it an hardware problem, that is solved by the journaling of ext3/4=?

Or ext2 has some kind of "misunderstaing" with eMMC?


Best regards,
