Subject: ubiattach error
Date: Tue, 20 Sep 2011 16:25:18 +0200 [thread overview]
Message-ID: <4E78A24E.7080000@televic.com> (raw)
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

------------------------------------------------------------------
- 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
