Subject: UBI+UBIFS on Read-Only NAND
Date: Thu, 05 Dec 2013 13:53:47 +0100 [thread overview]
Message-ID: <52A0775B.3080005@ADwin.de> (raw)
We had an old JFFS based system that had a dip switch connected to the
write-enable pin of the flash device, and it worked as expected. Users
were able to configure and use the system in r/w mode and then "lock"
the configuration.
I tried the same with our newer hardware, and UBI/UBIFS. I did not use
static volumes, since write support is essential for initial setup.
However, the system will not boot if the flash is write-protected in
hardware, because UBI assumes that it is R/W.
What is the suggested solution for such a setup? I could not find
anything in the FAQ or in the archive, but I may have been searching for
the wrong keywords...
Regards
Thomas Herrmann
