[linux-dvb] Re: DVB-S + DVB-T Linux Problem

[Raul Lucientes <rlr22@tid.es>]

Thanks Jean-Michel for your suggestions :-)

Im using a 2.4 kernel, and as you tell me, I had try to use the Technotrend
windows driver copying it to '/usr/lib/hotplug/firmware/tda1004x.bin' but
this the error log:

tda1004x_fwupload: Unsupported firmware
/usr/lib/hotplug/firmware/tda1004x.bin

Perhaps Im using a oldest kernel version ? .... where I could find a
"tda1004x.fw" to compiple with my dvb library ?

Best regards,
Raul Lucientes.

I've got problems too with a Hauppage Nova-T (SAA7146 chipset). Kudzu
doesn't pick it up.

The kernel 2.6.7 is supposed to fix some of those issues but the
Changelog is pretty scary:

<hunold@convergence.de>
	[PATCH] Make tda1004x DVB frontend driver work again

	Adrian Bunk noticed that the tda1004x DVB frontend driver was
         broken and sent a small patch that at least made the driver
         work again.

	There was a discussion afterwards about the kernel syscall
         interface, but at the end, the tda1004x DVB frontend driver is
         still non-functional.

	This re-applies the temporary band-aid.

I *think* this tda1004x.c file is what gets those DVB cards working. In
the kernel source there is this comment in this file:


*
     This driver needs a copy of the DLL "ttlcdacc.dll" from the Haupauge
     or Technotrend windows driver saved as
     '/usr/lib/hotplug/firmware/tda1004x.bin'.
     You can also pass the complete file name with the module parameter
     'tda1004x_firmware'.

     Currently the DLL from v2.15a of the technotrend driver is
     supported. Other versions can be added reasonably painlessly.

I found the driver on my windoze CD-ROM install - I've no idea if it's
the right version though.

So I installed the new-ish kernel with its source with apt, rebooted,
re-compiled the Nvida kernels against the new kernel, started X and...
nothing. It all froze up during X init and rebooted after a while,
probably because I was bashing my keyboard with rage :-)

Also, even with the new kernel and the firmware installed where it
should be, kudzu does not pick up the card at startup.

I might try to re-compile a 2.6.6 kernel with the patch from 2.6.7, but
right now it seems pretty hopeless to me... I'm such a luser - "It don't
work" :-)

(Besides, browsing the MythTV archives, apparently it's a mess to set up
with digital terrestrial. Doh.)
