No firmware needed for that device. All used chips are firmware "free".
DVB-C is not officially supported by that device but it seems to work
rather well. Biggest problem is hard coded LNA but I think I am going to
resolve LNA and GPIO issues later this summer when enhancing DVB-CORE
frontend issues. My plan is to add internal API, GPIO callbacks for the
demod and tuner in order to allow use of LNA etc. And of course some
param to API which sets LNA AUTO/ON/OFF, maybe numeric value for gain also?
regards
Antti
