Hi,
I have created a ubi image that I have programmed to NAND flash using
ubiformat. After I mount the ubifs, I am trying to write a 3MB file to
the flash and I am seeing some issues.
Here is the log:
--------------------------------------

--------------------------------------------
I have enabled UBI debug and CONFIG_MTD_NAND_VERIFY_WRITE.
Also, as an experiment, I used mtd_debug utility to write a 10MB image
to the flash and I don't see any issues there. So, it doesn't sound
like a driver issue?
HW ECC is enabled and I am presuming that no maintenance data is
stored in spare area for UBI/UBIFS (from documentation). I don't see
errors with ECC off.
Any help appreciated. Thanks.

Please, make sure you have all the latest UBI and UBIFS fixes:
http://www.linux-mtd.infradead.org/doc/ubifs.html#L_source
I think I fixed debugging problems recently. I suspect this fix may
help you:

Please, also take this into account:

Enabling debugging checks for verification is good. But please, bear
in mind that they make your system slower.
If you enable just debugging - it is light-weight, but if you also
enable additional checks - they are very slow, so you should later
disable them.

Thanks for the pointers. But I am using kernel v2.6.27.7. :-(
Meanwhile, I disabled all extra checks and
CONFIG_MTD_NAND_VERIFY_WRITE as recommended. Now, I see this when I
unmount and re-mount ubifs:
# mount -o sync -t ubifs ubi0:rootfs /tmp/flash/

If you look at the URL I sent you, you'll find 2.6.27 back-port.
All you need to do is to apply already prepared patches to your
tree.

I do not see this with the newest UBI/UBIFS. Please, update yours.

So I finally got all patches applied to my tree. I don't see an error
with mount operation now.
But I am seeing corrupted data messages.
