Hi all ..

we are using IMX-31 (ARM Core) processor with Linux 2.6 and redboot as boot
loader with jffs2 for NAND flash and facing the concerned problem :-

The board is booting fine but it sometimes takes 21 sec to boot and
sometimes takes 31 sec to boot which is a concern for us actually it takes
usually 21 sec and 31 sec sometimes 

If we remove the power after booting and again insert the power supply It
gives the following warning message related to jffs2 ....

JFFS2 notice: (878) check_node_data: wrong data CRC in data node at
0x011dec00: read 0x2464ba56, calculated 0x474915f8.

Having never experienced this before i do believe that this could be the
jffs2 related concern hence just thinking of using YAFFS to increase the
booting effeciency ...


I would remain thankful if any of you could share your experience or thaught
regarding this ...

Thank you
