Stefan,
actually I have an issue with the "ubi part" command.
Situation:
MPC8377 based board with 64MiB Nor- (u-boot etc.) and 1GiB Nand-Flash (ubi volume).
MTD devices look like this :
=> mtdparts
device nor0 <NOR>, # parts = 2 #: name size offset mask_flags 0: u-boot 0x00100000 0x00000000 0 1: FPGA 0x00200000 0x00100000 0
device nand0 <NAND>, # parts = 1 #: name size offset mask_flags 0: root 0x40000000 0x00000000 0
active partition: nor0,0 - (u-boot) 0x00100000 @ 0x00000000
defaults: mtdids : nor0=NOR,nand0=NAND mtdparts: mtdparts=NOR:1M(u-boot),2M(FPGA);NAND:-(root) =>
Setting the ubi partition to "root" fails :
=> ubi part root Creating 1 MTD partitions on "nand0": 0x000000000000-0x000040000000 : "mtd=0" UBI: attaching mtd2 to ubi0 UBI error: io_init: unaligned VID header shift 2 UBI error: ubi_init: cannot attach mtd2 UBI error: ubi_init: UBI error: cannot initialize UBI, error -22 UBI init error -22 exit not allowed from main input shell. =>

Did another test with a single NAND device :
=> mtdparts
device nand0 <NAND>, # parts = 1 #: name size offset mask_flags 0: root 0x40000000 0x00000000 0
active partition: nand0,0 - (root) 0x40000000 @ 0x00000000
defaults: mtdids : nand0=NAND mtdparts: mtdparts=NAND:-(root)
=> ubi part root Creating 1 MTD partitions on "nand0": 0x000000000000-0x000040000000 : "mtd=0" Bad block table not found for chip 0 Bad block table not found for chip 0 No space left to write bad block table UBI: attaching mtd1 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 UBI error: ubi_init: cannot attach mtd1 UBI error: ubi_init: UBI error: cannot initialize UBI, error -28 UBI init error -28 exit not allowed from main input shell. =>
To me the mtd numbering looks wrong in both cases - specififally: "ubi_init: can't attach mtdX"
Any hints ? Have I missed something ?
