Subject: Writing to the OCOTP on mx28 boards
Date: Fri, 28 Sep 2012 14:08:58 +0200	[thread overview]
Message-ID: <5065935A.8040302@free-electrons.com> (raw)

Hi everyone,

I'm trying to write down some data to the /dev/ocotp file, which is
basically a one time programming chip containing four bytes.

Using the command mw -b -d /dev/ocotp 0-3 0x01020304 writes down only
"4" to the first byte of the OCOTP, which is not quite what I was
expecting. What's the correct syntax for the mw command?

Thanks,
Maxime
