The "ubi part" command is failing for me on my PowerPC 85xx board. I am not trying to do anything special, just create the partitions and volumes so that I can try writing an ubi.img. It spits out enough information that it looks like it did work but it prints out an error nonetheless.
And of course there is the long standing issue of the reported MTD number not making any sense. But previous posts have discounted this as an issue.
Here is the snippet of the error:
UBI error: ubi_init: cannot attach mtd2 UBI: mtd2 is detached from ubi0 UBI error: ubi_init: UBI error: cannot initialize UBI, error -17 UBI init error -17
Here is a cleaned up version of the session log:
