osmo-cos - early code about a Card OS on CC32RS512

This repository contains some very early experimentation code about a Card Operating system (COS) for ChipCity CC32RS512 based smart cards.

The project is abandoned by now, due to lack of time (and lack of availability of more cards from Chipcity).

The project is part of the Osmocom Open Source Mobile Communications projects.


The official homepage of the project is
