Hi Pt

what are error messages ?

Please refer to this FAQ from MTD

http://www.linux-mtd.infradead.org/faq/jffs2.html#L_messages

======================= JFFS2 generates messages, is there a problem?

JFFS2 adopts the philosophy of keeping the user completely appraised of

what is going on.

This can catch out the unwary novice. The following messages can be

moved to a higher log level once you are sure that they are benign.

Empty flash at 0xXXXXXXXX ends at 0xXXXXXXXX This message is generated

if a block of data is partially written. It is generally not a sign of

any problem.

Name CRC failed on node at 0x00b620c8: Read 0x640c8ca3, calculated

0x795111fe or similar message about CRC failures. If you have ever done

unclean reboots - this is harmless.

=======================

Some the messages may be indeed being caused by power cycling the board

without a proper shutdown. Seems this is harmless.

Best regards

igor
