Hello! I think you mean UBIFS on UBI, right? > An observation: I cannot mount OpenWrt rootfs in u-boot, since it is > an UBIFS volume overlay on squashfs.

AFAIK UBIFS (also on linux) works only on UBI. I guess you could have squashfs on UBI, but on linux this requires mtdblock, hence it is squashfs on mtdblock on UBI. > Best, > Tony > > > > Function > > check_lpt_crc in unpack_ltab is failing.
