Hello,
Platform: Cavium CN5020
Filesystem: UBIFS
Flash Type: NOR
Flash Size: 8MB
Partition Details Kernel Log:
Creating 2 MTD partitions on "phys_mapped_flash":
0x000000000000-0x000000700000 : "Octeon BOOT partition"
0x000000700000-0x000000800000 : "Octeon test partition"
$mount -t ubifs ubi1:test /mnt/nor
UBIFS error (pid 851): init_constants_early: too few LEBs (12), min. is 17
mount: wrong fs type, bad option, bad superblock on ubi1:test,
missing codepage or helper program, or other error
(for several filesystems (e.g. nfs, cifs) you might
need a /sbin/mount.<type> helper program)
In some cases useful info is found in syslog - try
dmesg | tail or so
But JFFS2 is able to mount the same partition flawlessly. Shouldn't
UBIFS be able to do the same? What I would like to know is, is this the
expected behavior or a bug? If its a bug I would like to look into it.
Thanks and regards,
Philby
