[BPI-R3] create ubifs in uboot


I try to find some documentation how i can create an ubifs on the ubi-partition of nand.

Basicly it should hold the linux-kernel and an initrd file.

Can i do this completely in uboot or do i need to create an ubi-image from host-pc? How do i write the ubifs to the nand?

Regards Frank

Do you know Physical Erase Block size (PEB) and the minimum I/O size for r3 nand? Solution a seems to need the image too,or am i wrong?

I wonder why the partitions are not having a size/offset
