[NSA325V2] Bad blocks on mtd0? (3 replies)

Hello everyone! I was going to update uboot, kernel and debian on my NSA325 v2, but it seems i have got some problems.
I am running Uboot

root@nsa325:/# strings /dev/mtd0 | grep U-Boot
U-Boot 1.1.4 (Jul 18 2013 - 10:47:29) Marvell version: 3.5.9
If U-Boot Endiannes is going to change (LE->BE or BE->LE), Then Env parameters should be overriden..
U-Boot
** Invalid partition type "%.32s" (expect "U-Boot")
U-Boot code: %08lX -> %08lX  BSS: -> %08lX
Addresses %dM - 0M are saved for the U-Boot usage.
U-Boot BUG at %s:%d!

, kernel

Linux nsa325 3.18.5-kirkwood-tld-1 #1 PREEMPT Thu Feb 5 17:58:07 PST 2015 armv5tel GNU/Linux

on Debian 7.11 / OMV 2.2.14.
Before updating uboot, I checked for badblocks, and this happens:

root@nsa325:/# nanddump -f /dev/disk/by-label/down /dev/mtd0
ECC failed: 360
ECC corrected: 0
Number of bad blocks: 2
Number of bbt blocks: 0
Block size 131072, page size 2048, OOB size 64
Dumping data starting at 0x00000000 and ending at 0x08000000...

Otherwise with grep -i 'bad blocks' i got no errors. So, what should i do now? :) Thank you
