Patches to fix/change this are welcome. :) > Here is the snippet of the error: > > UBI error: ubi_init: cannot attach mtd2 > UBI: mtd2 is detached from ubi0 > UBI error: ubi_init: UBI error: cannot initialize UBI, error -17 > UBI init error -17 -17 == EEXIST. Looking at the code (build.c) shows that ubi_attach_mtd_dev() is returning this error code in case the MTD device is already attached. Even though the UBI implementation should handle this without any problems. I have to admit that I'm a bit out of ideas what's going wrong in your case. I just checked again and UBI works fine for me with the latest version: => mtdparts device nand0 <nand>, # parts = 3 #: name size offset mask_flags 0: bootloader 0x00100000 0x00000000 0 1: rootfs 0x01000000 0x00100000 0 2: ubifs 0x02f00000 0x01100000 0 active partition: nand0,0 - (bootloader) 0x00100000 @ 0x00000000 defaults: mtdids : nand0=nand mtdparts: mtdparts=nand:1m(bootloader),16m(rootfs),-(ubifs) => nand erase 1100000 2f00000 NAND erase: device 0 offset 0x1100000, size 0x2f00000 Erasing at 0x3ffc000 -- 100% complete.

Could be that this is a bug already fixed now. Otherwise you need to debug this problem yourself, since I can't reproduce it here.
