CRC problems with JFFS2
From time to time, when starting up from poweroff (deep standby) I see these messages appearing :
JFFS2 notice: (27) check_node_data: wrong data CRC in data node at 0x00645000: read 0xd608c0ba, calculated 0xda5f595a
The result is that enigma2 somethimes does not start properly (tuner config not correct or somethimes or bus error when starting enigma binary)
After a warm reboot, the messages are gone. they only appear in first boot from a coldstart. Is this a software or hardware error causing this?
Any idea what could cause this problem?
already tried to flash the image/firmware again, using DREAMUP and the "Repair Bad Sector" Option? It sometimes can happen that a sector in the Nand flash goes bad ... if you flash with DREAMUP the bad sector will get marked as BAD again and never get used anymore.
Anyway, I saw that message on my box already too a few times already. But never had any problems
Theorie ist, wenn man alles weiß, aber nichts funktioniert.
Praxis ist, wenn alles funktioniert aber niemand weiß warum.
Thanks for your tip. I'll try it out.
I also saw this message in dmesg :
Bad eraseblock 719 at 0x059e0000

The bad reaseblock is in the root partition. could it be related?
(nand is allowed to have bad eraseblocks at shipping. so for the moment I do not think a return for repair is needed.)
Is this forum also followed up by dream multimedia technicians itself?
