Hello,
Using the patches from Bo Shen to support the NOR flash on the Atmel
which patches?
SAMA5D31EK hardware platform I am trying to get a UBI root file system within the NOR flash, at offset 0x10000000 in the memory map, to work but get errors from the "ubi part" command using U-Boot 2014.04:
U-Boot> mtdparts
device nor0<physmap-flash.0>, # parts = 5 #: name size offset mask_flags 0: bootstrap 0x00020000 0x00000000 1 1: u-boot 0x000c0000 0x00020000 1 2: fdt 0x00020000 0x000e0000 0 3: kernel 0x00400000 0x00100000 0 4: rootfs 0x00a00000 0x00500000 0

U-Boot> ubi part rootfs UBI: attaching mtd2 to ubi0 UBI: physical eraseblock size: 131072 bytes (128 KiB) UBI: logical eraseblock size: 130944 bytes UBI: smallest flash I/O unit: 1 UBI: VID header offset: 64 (aligned 64) UBI: data offset: 128 UBI error: vtbl_check: volume table check failed: record 0, error 9
seems ubi does not find the volume table ... could you activate ubi error messages ubi_err() ?
UBI error: ubi_init: cannot attach mtd2 UBI error: ubi_init: UBI error: cannot initialize UBI, error -22 UBI init error 22
The UBI settings are:
(2048) Image Size (130944) Logical Erase Block Size (1) Minimum I/O Size [ ] mkfs.ubifs Space Fixup () mkfs.ubifs Options
*** UBI Image Properties *** [*] Create UBI Volume (10MiB) Root File System Volume Size (128 KiB) Physical Erase Block Size (1) Sub-page Size () ubinize Configuration File () ubinize Options
Any ideas as to what I have missed?
Did the ubi partition work under linux? Did you tried current ML U-Boot (there MTD/UBI and UBIFS is synced with linux 3.15) ...
