Добрый день!
С большими бубнами закатал кернел и rootfs на NAND (старая версия ubimkvol, watchdog, права на файлы и т.д.)
Делал в итоге в такой последовательности (переносил файлы с USB MFGTool не работает):
mount /dev/sda1 /mnt/cdrom/
flash_eraseall /dev/mtd0
flash_eraseall /dev/mtd1
ubiformat -y /dev/mtd1 (не знаю надо ли)
ubiattach /dev/ubi_ctrl -m 1
UBI: attaching mtd1 to ubi0

ubiblka: unknown partition table
ubimkvol /dev/ubi0 -n 1 -N data -s 16000000 (хотел сделать вторую партицию и все равно не до конца разбивает т.к. не поддерживает ключ -m)
ubiblkb: unknown partition table
mkdir -p /mnt/ubi0
mount -t ubifs ubi0:rootfs0 /mnt/ubi0/

В итоге все запускается вот соответств кусок загрузочного лога:

В итоге при запуске fdisk -l получаю мертвеца (точнее только консоль соответствующая умирает):

На всякий случай вкладываю device.c из кернела (который у меня как итоговый после патчей получается)
