I've tested this on our i.MX25 board. Here's what I get:
barebox:/ ubiattach /dev/nand0.rootfs
UBI: attaching mtd0 to ubi0
UBI: physical eraseblock size: 131072 bytes (128 KiB)
UBI: logical eraseblock size: 129024 bytes
UBI: smallest flash I/O unit: 2048
UBI: sub-page size: 512
UBI: VID header offset: 512 (aligned 512)
UBI: data offset: 2048
UBI: empty MTD device detected
UBI: create volume table (copy #1)
UBI error: ubi_scan_get_free_peb: no eraseblocks found
failed to attach: error 28
The kernel is able to attach the same device as follows:
UBI: attaching mtd3 to ubi0

UBI: logical eraseblock size: 129024 bytes

UBI: MTD device size: 122 MiB

UBI: number of PEBs reserved for bad PEB handling: 9
UBI: max/mean erase counter: 1/0
UBI: image sequence number: 1519924105
UBI: background thread "ubi_bgt0d" started, PID 852
Where should I look to diagnose this?
