[linux-dvb] Problems with Terratec Cinergy Piranha

[linux-dvb] Problems with Terratec Cinergy Piranha

[Esa Hyytia]

Hello list,

I bought today this USB stick (187f:0010) and tried to get it work in 32-bit Ubuntu 8.04:

 - Driver snapshot from today (http://linuxtv.org/hg/~mkrufky/siano)
 - Firmware is extracted from driver-cd (same as from terratec.net)
 - I also changed 'default_mode' to 0 in smscoreapi.c
 - make && make install seems to work properly
 - plugging the stick in a USB port gives the following error(s):

[ 2104.988097] smsdvb_hotplug: line: 330: SMS Device mode is not set for DVB operation.

Any hints what I could try to get further?

Thanks in advance,

Esa

That's your mistake -- now for DVB-T the default mode needs to be
left as 4 (that's DVBT-DBA-drivers; how that specifically differs
from mode 0 DVB-T I have no idea, but that's the way it is now)

Only mode 4 will work with yesterday's /siano snapshot, even
though the firmware is the same -- you'll also need to rename the
firmware to what the code expects:
dvbt_bda_stellar_usb.inp

There appears to be another copy of the smsdvb code in a repository
called somehow `hd' which differs slightly; the only difference I
looked at is one which I needed to apply for my 2.6.24-era kernel.
I need to look more closely at what else differs.
Hope that helps...

I have not tried this as for no apparent reason the stick
suddenly started to work. In any case, thanks to everyone
involved in supporting this device.

I also collected from the mailing list the instructions on how to
get this device running and added them at the end of the wiki page,

This is an experimental driver -- You'll notice that I did not merge
it into the master branch yet -- those alternative modes are for
external software applications, to use the driver in a way without
using the dvb core framework.

I plan to remove that from the driver, as I am working to convert it
100% to the standard linux-dvb api.

default_mode is set to 4 in the driver -- you just shouldn't mess with it.

That code is not for you :-P  That's for an unrelated experiment that
I was doing.

You think you needed the adapter_nr compat patch, but you dont -- if
you build from the "siano" tree, it will install the newer dvb-core
along with the adapter_nr interface.

Just dont use the hd tree.

The "isms" will all be removed before I merge the code into the master
repository.

Regards,

Mike

Which brings me to ask publicly what I've been trying to figure
out how to ask...

The device supports DAB under the supplied Home Cinema Windows
application, the reason why I bought it (DAB support, that is.
I have no Windows boxes).  It works and all.

DAB is about as far from DVB as, well, as it is.  There's one
DAB device support sourcefile, under video or something, but it
doesn't seem to deal with the composition of the multiplex
datastream.  Where is it appropriate for me to ask questions
about DAB, if anywhere?  Shirley, not this list...

And secondly, has anyone who has this adapter and can receive
DAB radio with it, captured that protocol and data and whatnot,
to enable some reverse-engineering/hacking?

Basically, I'm wondering, what does a non-DVB external software
need to say to the device, and what does the device say in return
(complete multiplex data, or only part thereof, or something),
in order to tune and listen to a DAB multiplex/channel...

Sorry guv, i'm overwriting my downloaded copy thereof repeatedly
with a random pattern of ones and zeroes formed by the statistical
cryptographic transformation (and computationally mathematically
proven, say wot) based on the highly sophisticated algorithm of
ROT-26ing the data, so you can rest assured I shan't poke my nose
in places it does not belong, until the next time I see something
curiously interesting

And it will also overwrite the hacked source I have in my present
kernel that enables a few obscure devices I have to function at all,
so I'm hoping to clear out all my accumulated hacks before I can
safely try a stock kernel again.  That's the unfortunate reason
I'm cherry-picking the best goodies out of new code selectively.

No worries, I'm clearing out my hacks, hopefully before I get
cleared out


thanks
