The on-flash layout did not change, so it should work. The "old" fastmap code had a number of issues, mostly related to powercuts and some logical issues. In 4.1 it saw a huge amount of rework and fixes, including UBI core code. >> It is just the old fastmap version. In v4.1 fastmap saw >> a massive update.

I was under the assumption that you are porting all UBI fixes to u-boot which are marked for stable. As the fastmap rework turned out to be much more than a few single fixes they are not in the Linux stable tree. >>> Maybe you are already aware of this and you have some work-in-progress >>> patches to share? >>> Otherwise, I might be able to spend some time working on this in the next >>> weeks. >> >> I'll happily help you! > > I am next week in Dublin on the ELCE so I have no time to look into > this issue ... maybe the week after ... I'm also at ELCE, maybe we can discuss this also in person.
