Finally, the first samples of the smart card chip (for the Osmocom CardOS project) have arrived. As opposed to the final smart cards, this one has been packaged in a DIL case instead of the usual thin credit-card sized plastic. The reason for this is quite simple: This way lots of I/O pins for debugging as well as JTAG can be accessible during COS development.
Here you can see the first incarnation of a veroboard connected to an adapter pcb inside an Omnikey smart card reader:
After confirming it worked, I soldered the wires directly to the adapter PCB, as can be seen here:
There is already a real PCB design that is currently manufactured, i.e. in a week or so there will be a picture of a clean, professionally-produced/etched PCB with all of the prototype pins exported.
In terms of the COS, I haven't done much more work than compared to the last posting, mainly due to a large number of other projects. But we will get there...
