Hello Pierre-Jean
Sorry for delayed response but it took some time.
It seem that it works.
The startup type could be something like this:

You may also need a Flash driver, it's on a way:

Note: Flashing is critical operation, it may lock your Kinetis flash for
good, no protection yet. Usage is on your own responsibility.
Regards
Ilija
