The DSP implements the PHY layer, which is proprietary. However, as the DSP is ROM code running on a different processor, with different address space, RAM and instruction set, there is no issue in terms of GPL licensing. The GPL-licensed OsmocomBB code simply instructs the other processor to do what's needed. > Of cource we can patch DSP and ask it to do whatever we want, like send raw > bursts to the host, but now osmocombb uses mostly DSP firmware written by > Texas Instruments, not its own opdnsource. Correct. We never claimed that the PHY layer (DSP code) was FOSS. There was once an university project about creating a software PHY compatible with OsmocomBB, but unfortunately (like way too often in academic research) the results were not contributed back as FOSS: http://www.benkeser.com/osmophy.pdf There are some ideas floating around of doing a new run of this using OsmoTRX as basis, but I don't know if there is any actual progress yet. Vadim should be able to say more about it. -- - Harald Welte <laforge at gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
