Hello

Thanks for the answer.
Hi

Thanks for the answer.
I would like ... but I think I'm going to a raw data storage in a ubi volume instead of a little jffs2 file system :(  (my need it is just to store some bytes of data) ...

We use the UBI/UBIFS sources from linux, so this part cames
from linux. And as fas as I know, nobody has tried to use
CONFIG_MTD_UBI_GLUEBI
in u-boot yet, so if you want to do this, you have to dig into
this part deeper. Patches are welcome ;-)

bye,
Heiko
