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

------------------------------------------------------------------
- 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.
