You're welcome. Obviously this is a first try, so things could need adjustm=
ent.

Edit your configuration, cpu model, etc.
Begin your work by modifying startup.S. Basic cpu setup, setup of the stack=
 pointer. Check linker.lds for memory areas. Once the RAM subsystem is func=
tional, you could enable the calls to adainit and _ada_main. If everything =
went ok, you end up executing code in Bsp_Setup. Theoretically you have at =
this point complete control. Even pulse a LED will be a great result.

Anyway, waiting for a physical board, I'll try to build a full-functional s=
imavr so I could write a BSP, and create fundamental infrastructure in the =
cpu hierarchy.

I'll come back ASAP.
