Tillitis has always been committed to open source. As we promised earlier, we continue to be committed to open licenses.
We originally chose “GPLv2-only” as the license for our Verilog and source code. We are now changing to the more permissive BSD 2-clause license for all Verilog and source code. The hardware (PCB, PCBA) license remains the same: CERN Open Hardware License Version 2 - Strongly Reciprocal.
The full license text is found in each repository, for example in the tkey-device-signer.
The main reason to change the license is to allow more people and organisations to use our design and our code. This is especially true for our software libraries, which could not be linked without affecting the linked code, but also all our other code.
We will start to change the license in our repositories on October 2nd.
