Yes. We would need to extend the Aspeed machines to instantiate 2 different SoCs (or more). This is something quite interesting to design. > Oh that’s a good idea actually. Maybe I’ll look into that as an alternative to the socket thing. Still, it might be something useful to submit anyways. Yes. Please do. Thanks, C.
