We are updating from 2012-03 to 2012-09 and after flashing our SOM
(Phytec PCM043 - imx35) we starting getting this error:
barebox:/ erase /dev/nor0.barebox
erase: Operation not permitted
It worked the first time, when overwriting the 2012-03 image and booted, etc.
We have tried a few intermediate Barebox versions and think it worked up to 2012-
07.
Any ideas what we now need to do to be able to overwrite Barebox?

did you unprotect first?
Best Regards,

Yes, just didn't include that in my snippet. The unprotect command did
not return an error.

I think you are the victim of a bug fix ;)
You probably registered the partition readonly. (see the 'ro'
flag in the mtdparts variable). Since some releases barebox
actually honors this flag:
