[Buildroot] Had anybody ever basically create JFFS2 image using BUILDROOT ???

[Чинков Андрей]

My question is simple and easy:

Had anybody ever basically create JFFS2 image using BUILDROOT ???

The reason of this question is that I can not create target JFFS2 image 
using buildroot-dailysnapshot.tar.bz2

May be there are other tools to create JFFS2 filesystem image for MIPSEL 
on Ubuntu/x86 ???

PS:

My host machine is Ubuntu8.04, x86
My target machine is MIPSEL

Thx.
