Hi everybody,
I need some help. It's the first time I try to hack a kernel module.
Pere Blay and I are trying to get a Genius DVB-T device (TVGo t02q)
working, and we're almost done (I think), but I'm stalled right now.
As I didn't get any responses from Aapo, I was wondering if some of
the more experinced hackers on this list could give us any advices.
Chips on this device include zl10353, mt2060 and m9206. I have what
appears to be a functional firmware, and with our patches to m920x.c
and friends the capturer seems to be tuning correctly, but for some
reason I can't get any data from /dev/dvb/adapterX/demux0 nor from
dvr0. I've attached some logs I've posted before (BTW you can read our
previous messages on this list, where there's also the firmware and
the patchwork :-).
Any ideas? Thanks in advance.
Regards,
