em28xx e kernel 2.6.26

[sbabaro]

dopo che tutto funzionava sotto il kernel stock della 12.1, mi viene la bella idea di ricompilarmi, come al solito, il mio kernel, tra l'altro impostando le opzioni per abilitare lo splash screen
Ora, la compilazione del 2.6.26 è andata a buon fine, funziona tutto, tranne la mia cinergy xs, che sotto il 2.24.5 andava tranquilla dopo aver installato i v4l-dvb-kernel
ora, con il nuovo kernel i moduli em28xx sono direttamente presenti nel kernel
quando attacco la schedina usb mi ritrovo che mi carica il modulo em28xx, ma mi cerca un fantomatico firmware xc3028-v27.fw che non so proprio dove andare a prendere
infatti cercando in giro, sembra che sia il firmware relativo ad un'altra scheda (da estrarre dai driver windows)
avete idee?

P.S.
in effetti devo dire che di v4l non ci capisco molto, e in linea si trovano delle risorse quanto meno sibiliine

[sbabaro]

continua ad essere tutto alquanto misterioso
comunque ho scaricato questo driver windows e tirato fuori il firmware, e tutto funziona
le istruzioni sono direttamente nel file perl

Codice: Seleziona tutto

 wget http://www.kernel.org/doc/Documentation/video4linux/extract_xc3028.pl

Ho avuto lo stesso problema con il 2.6.26 e la mia pinnacle usb tv. Solo che a me adesso non carica neanche più il modulo em28xx, ma potrebbe essere stato un errore mio. Appena ho tempo approfondisco.

[axj]

Guarda, non sono riuscito a risolvere il mio di problema, ma probabilmente ho risolto il tuo.... hai visto per caso qui la parte dei firmware?

http://www.2nrds.com/digital-tv-in-linu ... xx-devices


A me carica tutto invece adesso, il problema e che non mi crea la maledetta periferica

/dev/dvb/adapter0/frontend0': 2 No such file or directory

La cosa buffa è che il modulo me lo carica, e i firmware sono installati. Solo che non dev no party

[sbabaro]

giusto per la cronaca: settimana con il pc spento, riaccendo, ricollego la cinergy e.........

Codice: Seleziona tutto

xine-lib: error: File not found::  Sorry, No DVB input device found.

ha smesso nuovamente di funzionare
ora carica tutto regolarmente, crea il device video1, ma xine dice che non ci sono dvb presenti

[sbabaro]

ho riscaricato em28xx-new, ricompilati, insatllati ed ora mi carica da solo em28xx-dvb e mi crea la dir /dev/dvb
ora funziona

[axj]

Se mi dici come hai fatto sono più contento.... a me non funziona, e non mi compila quello che prendo con

Codice: Seleziona tutto

hg clone http://mcentral.de/hg/~mrec/v4l-dvb-kernel

Ergo necessito di aiuto...

Mi puoi dire che versione di kenerl hai???

[sbabaro]

devi scaricare em28xx-new, non v4l-dvb-kernel
http://mcentral.de/hg/~mrec/em28xx-new
e compilare questi
considera che con questi driver dovrai mettere un nuovo firmware, che scarichi dal link più sopra

[h8er]

ciao mi unisco alla discussione visto che ho appena comprato una Terratec Cinergy hybrid xs fm... io ho un kernel 2.6.25.10 ed ho seguito le istruzioni riportate qui per compilare il driver

http://mcentral.de/wiki/index.php5/Installation_Guide

ma ho un problema per quando rigurada il modulo em28xx-dvb che viene si compilato ma non mi è possibile caricarlo:

Codice: Seleziona tutto

>root#: modprobe em28xx-dvb
FATAL: Error inserting em28xx_dvb (/lib/modules/2.6.25.10/empia/em28xx-dvb.ko): Unknown symbol in module, or unknown parameter (see dmesg)

dmesg all'avvio riporta questo:

per quanto riguarda gli altri moduli nessun problema quantomeno em28xx_audio, em28xx_cx25843 e em28xx li vedo quando do un lsmod | grep em28xx e in dmesg non vedo altri errori. Ho provato a ricompilare i moduli ed il problema sembra esserci già in fasi di compilazione (vedi i vari WARNING: "dvb_xxxxx" [/disks/ext1/pkgs/internet/em28xx-new/em28xx-dvb.ko] undefined!)

make[1]: Leaving directory `/usr/src/linux-2.6.25.10'

ma non capisco il motivo, gli header del kernel sono installati correttamente e sono presenti i famigerati file necessari per la compilazione come al step #9 della guida. Qualcuno mi puo' aiutare ? Forse è un problema con le variabili d'ambiente e i sorgenti del kernel ?

ciao e grazie

EDIT: Risolto tutto, il kernel che avevo compilato non aveva il modulo dvb_core, ricompilato il kernel ed adesso tutto funziona a meraviglia, strano comunque che da nessuna parte venga esplicitamente detto che quel modulo è necessario, spero possa servire a qualcuno
