Please help me how to flash the ubi image from barebox.
I generated the ubifs image using the mkfs.jffs2, then I created the ubi image using the ubinize. I am trying to flash this ubi image on NAND.
I tried in two ways
1) I flashed the UBI image directly on /dev/nand0.rootfs.bb(erased the partition before flash).
In this method I am getting the errors like below

2) I executed the below commands from barebox
#erase /dev/nand0.rootfs.bb
#ubiattach /dev/nand0.rootfs
After this command it created the /dev/ubi0
#ubimkvol /dev/ubi0 rootfs 0
After this command it created the /dev/ubi0.rootfs
After these commands I copied the ubifs image on to the /dev/ubi0.rootfs.
#tftp root.ubifs /dev/ubi0.rootfs
Now I booted the kernel, in this method, I am getting the error like the volume layout not found.
Please tell me which method is correct. If the above two methods are not correct, please suggest me the correct method.
Thanks
