Boot from SPI Nor Flash on HiFive Unleashed Board

Hi all,

I am Working on HiFive-unleashed board, trying to boot the image from on board SPI Nor flash using ubifs root file system.

Is there any reference for usage of ubifs on Nor Flash Memory? We have 32 MiB Nor Flash and 4Kib LEB min/max page size is 1 byte. Using ubiformat ubidetach and attach, we are trying to mount ubifs file system, but we are facing mount: /mnt: wrong fs type, bad option, bad superblock on ubi0:vol_1, missing codepage or helper program, or other error ubi error.
