pvr-500 no signal on second tuner

Dec 8, 2009, 8:08 AM

Post #1 of 6 (3807 views)

Hell All,

I've got a pvr-500 that's only getting a signal on the first tuner:

# ivtv-tune -c 3 -d /dev/video0
/dev/video0: 61.250 MHz (Signal Detected)

# ivtv-tune -c 3 -d /dev/video1
/dev/video1: 61.250 MHz

I've disabled serial/parallel support in the bios and removed all other cards in hopes of removing irq conflicts, but no luck. I've tired the card in each of the 3 pci slots.

I get a 0 byte file when I cat /dev/video1:

# cat /dev/video0 > v0.mpg
# cat /dev/video1 > v1.mpg
# ll v*
-rw-r--r-- 1 root root 1155072 2009-12-08 10:25 v0.mpg
-rw-r--r-- 1 root root 0 2009-12-08 10:25 v1.mpg

This is a fresh install of MythDora 10.21. I've included as much information below as I could think of... let me know if I missed something. I've got acpi=force on my kernel command line, as suggested by a google search, but it hasn't helped. Any and all suggestions greatly appreciated!

^^^

This second CX25843 chip has gone braindead or the I2C bus from the
second CX23416 chip isn't working. That's chip decodes analog video
signals into digital data. Until it responds no video will work.

Check

$ modinfo ivtv
$ modinfo cx25840

and see what debugging options you can turn on in /etc/modprobe.conf for
these modules. It might give insight into what the problem is.

Highest probability cause is that that CX25843 is dead.
If you're lucky, it's only some Linux I2C subsystem problem in software.

Andy

Hi ANdy, thanks for responding.

I turned on debug for both modules:

# cat /etc/modprobe.d/mythtv.conf
#parm: debug:Debug level (bitmask). Default: 0
# 1/0x0001: warning
# 2/0x0002: info

option ivtv debug=0x020B

#parm: debug:Debugging messages [0=Off (default) 1=On] (int)

I've included more from dmesg below, but this looks relevant:

ugh. would this cause system instability? I've had some random reboots. If
so, there is a module parameter to disable the 2nd tuner to restore stability?

Yes. This is further confirmation that communications with the second
CX25843 chip isn' working. The cx25840 module is misdetecting it as a
CX23885 A/V core - a fallback position.

Random reboots would be caused by PCI bus problems. That would be more
likely the fault of a defective CX23416 chip or bad interactions between
the PCI bridge on the PVR-500 and the motherboard chipset. (VIA chipset
are problems at times.)

So try

# modprobe ivtv cardtype=0,-1

to autodetect the first unit on the PVR-500 and to ignore the second
unit.

You might have some luck with blacklisting the ivtv module so that it
doesn't load at boot and then modprobing it later when the flurry of PCI
bus activity at boot has died down. I wouldn't get my hopes up though.

You should try an test the board in a Windows machine. The I2C
subsystem debug messages are compiled out of the kernel by most distro's
by default. It's hard to see what is going on the i2c buses without
recompiling the kernel. :(

hmm... but it's loading that same firmware for the first tuner...

ok... here's the dmesg with that modprobe option set:

so it ignores the 2nd tuner... but the avcore firmware is loaded for tuner 1 with no problem.

I'd rather rebuild a kernel than run a windows machine. :-) Just tell me what
I need to enable in the kernel...

You've got an older version of the cx25840 module that has a bug where
it would switch firmware name strings in a system with a mixed set of
cards having CX2584[0123], CX2388[578], and CX2310[012] chips.

The latest v4l-dvb repository has that fixed:

http://linuxtv.org/hg/v4l-dvb/tip.tar.gz

But getting a patched up cx25840 module isn't going to help. I know the
card has 2 CX25843 chips, and we know one is being misdetected as a
CX23885 because attempts to read the the ID register ove the I2C bus are
returning 0. For a CX25843, the ID register should return 843
(surprise).

Not exactly. From your previous post:

It probably loaded the the "v4l-cx25840.fw", but by the time it reports
back to you, the filename has swapped around due to the aforementioned
cx25840 module bug.

None the less, you should probably unload both the ivtv and cx25840
module when performing tests when you reload modules, until you have a
fixed cx25840 module.

In

linux/drivers/i2c/algos/i2c-algo-bit.c

detailed debugging is is #ifdef'ed out by the 'DEBUG' define. The
i2c_algo_bit module parameters of interest are "bit_test" which may be
compiled into your kernel by default. Set it to one to have the bit
banging algorithm try and test for a stuck bus. Also "i2c_debug", which
can be set to a value of 0 to 3 for various levels of debugging
verbosity.

In the ivtv module, I would recommend turning on at least the i2c debug
flag and the high volume debug flag in the debug module option.
The ivtv module also has 2 i2c bus master implementations to choose
from:

newi2c=0 forces the i2c_algo_bit algorithm
newi2c=1 forces an ivtv internal algorithm

On newer versions of the ivtv module from the main v4l-dvb repository
there is also an i2c_clock_period module parameter you can twiddle to
slow down the I2C bus when using the i2c_algo_bit algorithm.

In the cx25840 module, the debug=1 option will provide some insight into
the detection process used by that module.

In reality, all of the above is going to help you collect alot of
information on when and where exactly the I2C bus transactions are
failing. That does not mean it will necessarily provide any insight as
to why the CX23416 and CX25843 fail to communicate with each other over
the I2C bus.

Andy
