Subject: static vs. dynamic UBI volume
Date: Tue, 19 Jan 2010 09:41:46 -0500 [thread overview]
Message-ID: <dbdb2ea61001190641l14a0603kfe9b45f52576da60@mail.gmail.com> (raw)
Can a UBI volume be declared vol_type=static, but mounted with "ro"?
Conversely, if a volume is declared vol_type=dynamic, is it acceptable
to mount "ro" or "rw"? I'm trying to understand if there are
dependencies between the two.
I'm seeing a very occasional problem on a volume that is
vol_type=dynamic, and is mounted "rw" during startup, then finally
"ro". The ubiattach works fine, but when trying to initially mount
(as "rw"), I've seen...

Not sure if this is corruption within NAND or something else.
