Bugreport: mkfs.jffs2

Bugreport: mkfs.jffs2

[Wolfram Gettert]

Hi,
I want to report two bugs on mkfs.jffs2 Revision 1.44

1.
I tried to create a file sytem image with this commandline.

mkfs.jffs2 -l -e 0x20000 -D devtable.txt -d rootfs -o test.img

The file devtable.txt contains a line  

----8<-----
/dev/input   d  755     0       0       -       -       -       -       -
----8<-----

and the rootfs directory contains a directory 

rootfs/dev/input


Of course it is my fault that I put the /dev/input directory in the device table
and in the rootfs. But never the less the result is a jffs2 image which is not
usable. Mounting it on the host with mtdram mtdblock .... freezes the PC and on
the target I cannot mount it too.

So there should be an error message or something like "Omitting directory xyz
from devtable already present"


2.
It is not possible to create a directory with devtable in "/"
Devtable contains this line

/opt   d  755     0       0       -       -       -       -       -

I get this message:

mkfs.jffs2: skipping device_table entry '/opt': no parent directory!



Please put me on CC, I am not subscribed to list.

So what is the problem?

I am using mkfs.jffs2: revision 1.43 with devtable entries like

/dev/input       d   755     0       0       -       -       -       -       -
/dev/input/event c   640     0       0       13      64      0       1       1

and it works just fine...

General suggestions:

*	Make sure you use the latest mkfs.jffs2;
*	Try to exclude summary patch and to see what happens;
*	Enable JFFS2 debugging messages and provide the output in the next 
report;
*	Make sure you put your JFFS2 image on the flash correctly. To do 
this you might erase your flash (flash_eraseall -j), mount it and copy 
your files there by means of "cp -r -a";
