[ubifs] "cannot parse device table file 'device_table.txt'"

[Gilles]

Hello

I'd like to compile Ubifs in uClinux, but am getting the following
error:
===========
...
/usr/src/uClinux-dist/user/mtd-utils/mkfs.ubifs --squash-uids -m 2048
-e 204800 -c 1024 -d /usr/src/uClinux-dist/romfs -D device_table.txt
-o /usr/src/uClinux-dist/images/rootfs.ubifs

Error: count cannot be zero if increment is non-zero
Error: cannot parse '/dev/mtdblock0     b       640     0       0 31
0       0       1       -'
Error: cannot parse device table file 'device_table.txt'
make[5]: *** [image.rootfs.ubifs.force] Error 255
===========

Google didn't return much information, but it seems like mkfs.ubifs is
part of mtd-utils:
http://mtd-utils.sourcearchive.com/documentation/20090606/devtable_8c-source.html

I tried to copy the manufacturer's "device_table.txt" in ./romfs/, but
am still getting the same error.

Does someone know the cause for the error?

Thank you.

It seems like that device table line is indeed incorrect, or what do you
expect mkfs.ubifs to do?

I used a sample that comes with uClinux and is considered a reference
to use. If there's more information about what value to put in that
column or a valid file that I could use, I'm interested. Thank you.

I do not know the right format for the device table either. In your case
you have: start = 0, increment = 1, count = -;

I do not know what "-" means, but mkfs.ubifs interprets it as "zero" and
then complains that you ask it to create zero devices starting from
number zero with increment 0.

May be this '-' means something and mkfs.ubifs does not properly handle
that?

I guess not too many people use Ubifs with uCLinux yet, which might
explain why the samples provided with the distro don't work. I'll read
up on that file and try to figure out why mkfs.ubifs isn't happy.

Thank you.

In case someone else has the same issue, here's the correct line:

/dev/mtd0	c	640	0	0	90	0	0	0	-
/dev/mtd1	c	640	0	0	90	2	0	0	-
