I have this board on my desk. You can get them for free from ST if you are in 
the US. As I am working on lisa/m v1.1 l added forward compatibility to this 
chip.

The problem I see here is that the toolchains are in very early stages in 
supporting this new core, so it will take a while until they are stable enough 
to be used on production systems. But I am looking forward to that.

Cheers Esden
