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, written 0 bytes UBI error: ubi_io_write: error -5 while writing 512 bytes to PEB 2:512, written 0 bytes UBI error: ubi_io_write: error -5 while writing 512 bytes to PEB 3:512, written 0 bytes UBI error: ubi_io_write: error -5 while writing 512 bytes to PEB 4:512, written 0 bytes UBI error: ubi_io_write: error -5 while writing 512 bytes to PEB 5:512, written 0 bytes 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 -- Jürgen Lambrecht R&D Associate Tel: +32 (0)51 303045 Fax: +32 (0)51 310670 http://www.televic-rail.com Televic Rail NV - Leo Bekaertlaan 1 - 8870 Izegem - Belgium Company number 0825.539.581 - RPR Kortrijk _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
