Welcome to the Osmocom Card Operating System¶

Osmocom COS (or short OsmoCOS) was the idea for an experimental Card Operating System for smart cards,
specifically for those based on the ChipCity CC32RS512 microcontroller.

It never became much of a COS, but the early beginnings of a development environment for COS development.

Starting Points¶

• CC32RS512JTAG
• CC32RS512QEMU

Mailing List¶

We used to have a mailing list for developers of this project. Its archive is at https://lists.osmocom.org/hyperkitty/list/osmocom-cos@lists.osmocom.org/

GIT repositories¶

The following git repositories are relevant to this project:

• https://gitea.osmocom.org/sim-card/qemu (qemu model for cc32rs512)
• https://gitea.osmocom.org/sim-card/osmo-cos (actual code, early testing but hopefully some cos in the future)
