 Hello,
 
  I am trying to upgrade 31 to 35 following the instructions:
  http://qtmoko.org/wiki/Update#Updates
  but does nothing.
 
 You first need to install the packages:
 edit the file /etc/apt/sources.list and add the line
 
 deb http://qtmoko.meurisse.org /
 
 then run:
 #apt-get update
 #apt-get install qtmoko
 
 Remember: do not try to update to v35 if you installed QtMoko on NAND.
 
 Regards

Re: GSM Firmware Flashed, now UBIFS problem and Kernel Panic

[giacomo 'giotti' mariani]

Hello,

If there is a better solution that preserves the FS,
  I would be happy to learn about it.
  

  I wonder if it would be possible to boot into a distro on the sd card
  and mount the nand partitions. Then you could save /home. Just a thought.
  

  Yes, it is: just mount  -t jffs2 /dev/mtdblock6 /mountpoint
  

  Thank you all for your input..

  I put a qtmoko v35 on an SD card.. an on terminal I did:

  mkdir /home/root/nandfs
  mount -t ubifs /dev/mtdblock6 /home/root/nandfs

  but sadly that doesn't work.. dmesg tells me:

  UBIFS error: ubifs_get_sb: cannot open /dev/mtdblock6, error -22

  Any ideas?

  Cheers,
  

I think you need to attach the ubifs before mounting.  See
http://openmoko-public-mailinglists.1958.n2.nabble.com/UBI-success-story-td4218730.html
for the steps, though unless you want to reformat, you shouldn't follow
all of them.

Alternatively, you can follow http://wiki.openmoko.org/wiki/UBIFS :
# apt-get install mtd-utils # if you are on qtmoko

# ubiattach /dev/ubi_ctrl -O 2048 -m 6
# mount -t ubifs ubi0:om-gta02-rootfs /media/om
# ls /media/om

Anyway it could be a problem related to ubifs instability, which is a 
topic recently discussed in mailing list [1]. You can follow that tread 
and try to:



Guy who'll have ubifs trubles please try to:

1. disable bulk read in fstab and check if problem will still exist.
2. do nanddump and post it or try to reproduce bug with nandsim. (i
guess ubifs guys can fix problem in case if such dump exist quite fast)


Regards
  Giacomo
