Uusi DVB-T2 kortti ja musta ruutu? (RATKAISTU)

Postby tikola » 04.06.2016 9:47

Vaihdoin vanhan Haupage DVB-T kortin uuten DVBSkyn DVB-T2 korttiin. Laite näkyy /dev/dvb hakemistossa. lspci kertoo kaiken olevan reilassa, mutta kuvaa ei näy. En siis muutellut channels.confia mitenkään vaan oletin, että vanha channels.conf kelpaa tavallisten SD kanavien kanssa laakista. Lokiin ei tule muuta kuin normaalia "kanava ei virittynyt" tavaraa. Ei kai kortin vaihto vaadi muutoksia toimivaan channels.conf tiedostoon, jos kerran pysytään samoissa SD taajuuksissa. Vai kaipaako siirto DVB-T DVB-T2 korttiin uuden virityksen?

Ajurit ja firmware latautuvat virheittä?

Kyllä tai en ainakaan nopeasti löytänyt lokista mitään. Mistäs noita kannattaisi tarkemmin katsoa? dmesg, lsmod, syslog jne.?

dmesg on hyvä lähtökohta.

Mikä tuo firmware for demod oikein on? Siellä asennushakemistossa näytti olevan pääsasiassa erilaisten TV korttien tiedostoja. Joten meneekö se niin, että ajurit ovat erikseen ja firmware demoduloinnille on erikseen? Eikö Firmware kuljekkaan kortin mukana jossain muistipiirissä vaan se pitää tuoda niille erikseen tietokoneen kautta. Tuo lataamani .fw tiedosto näytti olevan binääriä, joten sen enempää siitä ei tolkkua saanut. Tuossa nopealla googlauksella hyvä selitys:

https://wiki.ubuntu.com/Kernel/Firmware

Kuka nuo .fw tiedostot tekee? Onko se kortin valmistajan tekosia vai open source yhteisön, joka on tehnyt ajurin?
