Hello,
When I want to run 'ubiattach' I get this error:
barebox:/dev erase nand0.root1.bb
Skipping bad block at 0x08000000
Skipping bad block at 0x08020000
barebox:/dev ubiattach nand0.root1
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_io_write: error -5 while writing 512 bytes to PEB 0:512,
written 0 bytes
UBI error: ubi_io_write: error -5 while writing 512 bytes to PEB 1:512,

UBI error: ubi_io_write: error -5 while writing 512 bytes to PEB 2:512,

UBI error: ubi_io_write: error -5 while writing 512 bytes to PEB 3:512,

failed to attach: I/O error
------------------------------------------------------------------
- I use a imx27, and our HW is based on the imx27pdk.
- We use the BI-swap solution to work around the nand flash HW bug (2kB
pages are load in 512 chunks, mangling the spare area) (so
drivers/mtd/nand/nand_imx.c is patched).
- I see UBI detects a sub-page size of 512B, what does that mean?
Because in the UBI menu config "drivers - mtd - NAND - select nand
pagesize you want to support booting from", I must take '2048 byte page
size'; with '512 byte and 2048 byte pagesize' selected the board does
not boot.
- I use LTIB from CVS (not the freescale one), that I have patched
according to the imx28 BSP from freescale to support UBI
Kind regards,
Jürgen

first do 'ubiformat' in linux or flash an ubi image. Then you can attach
to it.
Mark: you can only attach 1 mtd0
After a lot of reading and trial-and-error, now I understand ubi and ubifs.
