Post subject:  TV card based on Zoran chip
Hi..
I'm trying to get working a TV Wonder Pro card based on Zoran 36120 chip.

First, I've tried with zoran.o module. The card is detected :

Linux video capture interface: v1.00
i2c: initialized
PCI: Found IRQ 10 for device 00:0d.0
zoran: Zoran 6120 (rev 2) bus: 0, devfn: 104, irq: 10, memory: 0x00000000.
zoran: 1 Zoran card(s) found.
zoran-0: installed Genius Video Wonder PCI Video Capture Card

... but when I try to run xawtv, scantv, etc, I get the followin errors:

v4l2: open /dev/video0: No buffer space available
v4l2: open /dev/video0: No buffer space available
v4l: open /dev/video0: No buffer space available
no grabber device available

Then I've found that there is another module that could work (zr36120.o), but I've realize that It's not compiled into /lib/modules.
I've found the sources of this module in /usr/src/linux, so I've compile the kernel again (making sure that
CONFIG_VIDEO_ZR36120=m it's on it), and again I've found that make modules_install didn't copy zr36120.o into /lib/modules.

Finally I've tried to copy this module by hand (with zr36120_i2c and zr36120_mem), but I can't insmod it :

zr36120.o: unresolved symbol zoran_i2c_bus_template

It's seems to depend on zr36120_i2c, but I can't install it neither:

zr36120_i2c.o: couldn't find the kernel version the module was compiled for

Have anyone made this chip work with these drivers? I would very much appreciate any clues on this.

Thanks.

Mariano

how about this, in this order;

modprobe i2c-old
modprobe saa7110
modprobe adv7175
modprobe zoran

Thanks for the hint, but the same problem:

v4l2: open /dev/video0: No buffer space available
v4l2: open /dev/video0: No buffer space available
v4l: open /dev/video0: No buffer space available
no grabber device available

Anyone has any ideas on this?

Thanks!

I realise this is a very old post, but in case anyone else arrives here...

The Zoran drivers were removed from recent kernels, I think they did not compile properly. Definitely won't work with recent (R5D1 upwards) Mythtv distributions.

I found someone (Joe Freise) who has produced a patch for Kernels 2.6.x, so if you have a Zoran 36120 based card, you may need to build the drivers, or else wait for them to be tested & included in newer kernels.

I have a Zoran capture card & will be attempting to get it working with R5D1.
