Artem,

Thanks for the help on upgrading out linux 2.6.33 kernel with the latest = UBIFS updates. I managed to merge the UBI/UBIFS specific code from th= e link you gave me (I took the latest and greatest) and I have a kernel tha= t now compiles successfully. Now we get the following error when the = UBIFS file system is mounted:

&n= bsp;

UBI: attaching mtd18 to ubi0

UBI error: io_init: bad write buffer size 0 f= or 1 min. I/O unit

ubiattach: error!:= cannot attach mtd18

&nbs= p; error 22 (Invalid argument)

UBIFS error (pid 916): ubifs_get_sb: ca= nnot open "ubi0:tntvar", error -19

mount: mounting ubi0:tntvar on /usr/local/tntvar failed: No such de= vice

We are suspecting now that this may be because we need to upda= te the ubifs tools (or create the ubifs with different cmd args) so that th= ey are in sync with the latest kernel. If you have any ideas on this = it would be great - right now I will be researching if our hypothesis is tr= ue and how to resolve it.

Thanks Dave

I'm guessing that you're using m25p80, which is missing this mainline patch in the backport tree: commit b54f47c8bcfc5f766bf13ec31bd7dd1d4726d33b Author: Brian Norris Date: Tue Jan 31 00:06:03 2012 -0800 mtd: m25p80: set writebufsize Artem, There was a series of 'writebufsize' fixes that may be missing from multiple backport trees.

OK, I just put up my own github backport tree, with branches for v2.6.32 through v3.3. I think your v3.4+ repos are fine. URL: git://github.com/computersforpeace/UBIFS-backports.git https://github.com/computersforpeace/UBIFS-backports.git Branches: ubifs-v2.6.32 ubifs-v2.6.33 ubifs-v2.6.34 ubifs-v2.6.35 ubifs-v2.6.36 ubifs-v2.6.37 ubifs-v2.6.38 ubifs-v2.6.39 ubifs-v3.0 ubifs-v3.1 ubifs-v3.2 ubifs-v3.3 Each branch should have some version (amended when necessary) of the following commits. Note that docg3 wasn't merged until v3.2. Also, spear_smi wasn't merged until v3.4 and was already fixed in the appropriate backports, so it is omitted from this list.
