I'm building U-Boot from the FSLC (repo/fork) on an i.MX6 U-Boot 2013.10-00012-g5bc3118-dirty (Nov 19 2013 - 09:17:18) CPU: Freescale i.MX6SOLO rev1.1 at 792 MHz
After I made a small change today in the NAND FLASH layout, I can no longer use UBI from U-Boot. Here's what I see today: MyBoard > mtdparts default MyBoard > mtdparts device nand0 <gpmi-nand>, # parts = 4 #: name size offset mask_flags 0: boot 0x001e0000 0x00000000 0 1: env 0x00020000 0x001e0000 0 2: linux 0x00f00000 0x00200000 0 3: fs 0x06f00000 0x01100000 0 active partition: nand0,0 - (boot) 0x001e0000 @ 0x00000000 defaults: mtdids : nand0=gpmi-nand mtdparts: mtdparts=gpmi-nand:1920k(boot),128k(env),15m(linux),-(fs) MyBoard > ubi part linux UBI: attaching mtd1 to ubi0 UBI: physical eraseblock size: 131072 bytes (128 KiB) UBI: logical eraseblock size: 126976 bytes UBI: smallest flash I/O unit: 2048 UBI: VID header offset: 2048 (aligned 2048) UBI: data offset: 4096 UBI error: ubi_read_volume_table: the layout volume was not found UBI error: ubi_init: cannot attach mtd1 UBI error: ubi_init: UBI error: cannot initialize UBI, error -22 UBI init error 22 Notice that when I try to access the 'linux' partition, it's trying to use mtd1 (env). In fact, it doesn't seem to matter at all what partition I try to access, it always wants to use mtd1. Today, I changed the MTD layout from mtdparts=gpmi-nand:896k(boot),128k(env),15m(linux),-(fs) to mtdparts=gpmi-nand:1920k(boot),128k(env),15m(linux),-(fs) I then rebuilt my Linux and reinstalled the partition. Linux is totally happy with this new layout, but U-Boot doesn't like it at all. Just to make sure I have this right, I just restored the previous layout and everything works as expected. What am I missing? Why is UBI not working with this layout?
