I use U-Boot 2011.03
I have no idea how to save the Image on a ubi, sorry I'm quiet new to
U-Boot. I tried the following instructions without any success
nand write.ubi/ubifs
nand write.ubi
nand write.ubifs
ubi
help ubi
Where can I find the manual for nand and ubi? I didn't find it on the
denx wiki.
