[Buildroot] [Fwd: Re: Problem with jffs2 image creation.]

[Cyril HAENEL <chaenel@free.fr>]

I use the default configuration : make at91sam9260dfc_defconfig

By default buildroot build 2 images, ext2 and jffs2, I have not changed 
any option in menuconfig :

[nlc at nlcLaptop buildroot]$ ls -l binaries/at91sam9260dfc/
total 15444

If I mount the ext2 image on my laptop everything is OK (devices are 
presents in /dev), and the image works fine when I put it in the board.
But when I mount the jffs2 image on my laptop, /dev, and even /etc are 
empty ! And of course the image doesn't work on the board.
ext2 and jffs2 images seems to not be generated with the same tool. I 
think there is a problem with the mkfs.jffs2 tool ?

You mean when you use an ext2 image (just changing from buildroot config) they create necessary files on /dev?

Send your config file.
