[linux-dvb] Hauppauge WinTV-NOVA-T-500 New Firmware (dvb-usb-dib0700-1.20.fw) causes problems

[Thomas Goerke]

[-- Attachment #1.1: Type: text/plain, Size: 442 bytes --]

I have been using the dvb-usb-dib0700-1.10.fw firmware for the past month
with no issues.  After following the instructions on
http://linuxtv.org/wiki/index.php/Hauppauge_WinTV-NOVA-T-500 and updating
the firmware to dvb-usb-dib0700-1.20.fw the card was no longer useable.
When using Mythbuntu backend the card was not detected correctly and gave an
unknown error.  Rolling back to dvb-usb-dib0700-1.10.fw corrected the
problem.

Well I'm glad the 1.20 support didn't just get checked in then.
Thanks for doing this testing.

Do you happen to have the dmesg output from the failed attempt, which
might have information on the nature of the failure?  I would like to
get to the bottom of the issue.

Weird, once I cleaned up my fw files, things went very well with MythTV
using fw 1.20, no reconfig or anything else needed.

Just to be clear, Nicolas, are you using a WinTV NOVA-T 500?  This
could be an issue with Thomas's particular product if your experience
is based on a different product.

Devin,  I looked at the dmesg output and it showed no errors.  So I tested
it again using both symbolic link and hard copy.  This time it worked
correctly.  I am not sure what was causing the problem before but rolling
back to the .10 definitely fixed it.  Apologies for the multicast on this
but all seems ok now using the .20 firmware.

Hmmm...  You're the second person to see that behavior.  Weird.

Did you apply the patch I sent out for the driver as well, or did you
just replace the firmware file?

Devin,

I did a little more debugging and it seems that the I still have a problem
with the .20 version.  However, you only see it after a cold reset ie when
you need to load the firmware.  See below for the first dmesg which is with
the .20 firmware.  As you can see the card is found but only in a cold
state.  The second dmesg is with the .10 firmware and the card is found
firstly in a cold state and then in a warm state.  Each of these dmesg
outputs have been after a power off from the power supply for 10 seconds ie
no power to backplane.

I have not applied the patch as I followed instructions on
http://linuxtv.org/wiki/index.php/Hauppauge_WinTV-NOVA-T-500 which doesnt
mention this.  I am using the latest v4l-dvb source. 

I can apply the patch to test if required.  Can you please let me know where
this is and I will try it.

Wow, that's so early in the loading process for the device, it's hard
to see how that can have anything to do with my i2c changes.

Patrick, do you have any changelogs that describe the differences
between 1.10 and 1.20 other than the addition of the new i2c API?

Ok, so it looks like there are i2c errors accessing the dib3000 and
mt2060.  That's bad, but at least it's exercising the new code.

Let me look at the code and see what I can find out.

Let's try this to rule out whether it's the new i2c interface or some
other aspect of the 1.20 firmware:

Add the following line to the dib0700_devices.c at line 78:

st->fw_use_legacy_i2c_api = 1;

It should end up looking like:

=======
static int bristol_frontend_attach(struct dvb_usb_adapter *adap)
{
        struct dib0700_state *st = adap->dev->priv;

	st->fw_use_legacy_i2c_api = 1;

        if (adap->id == 0) {
....
=======

That will tell it to fall back to the legacy i2c interface (which was
working fine for you in the 1.10 firmware).

Make that change, reboot your system, and send me the dmesg output so
we can see if you still get i2c errors.

Thanks,

Devin

Well that's promising.  Could you please reboot the system a few times
and test both cold and warm starts so you are comfortable that
everything is working?

Once you're confident everything works, could you please try the following:

1.  Comment out the "st->fw_use_legacy_i2c_api = 1" line you added in
the previous email
2.  Add "| I2C_M_NOSTART" to line 46 of mt2060.c so it looks like the following:

{ .addr = priv->cfg->i2c_address, .flags = I2C_M_RD | I2C_M_NOSTART,
.buf = val,  .len = 1 },

make, make install, reboot

Then let me know if the dmesg output contains i2c errors (and send the
output if it does).

We're getting close here....

Thanks for doing this test.  I've done some additional reading which
suggests the mt2060 has an extended history of flaky i2c behavior.
Given that I don't have the hardware, I don't think I'm going to be
able to debug it further.  I'm going to submit to have that device
fall back to the legacy interface, so it shouldn't be any worse with
1.20, but at least it won't block other devices that use 1.20 from
being committed.

Thanks,

Devin

OK np.  For the time being I will roll back to the .10 firmware and use the
v4l-dvb tree.  I am not sure of then benefit of the .20 firmware as the .10
version has been very stable.

Let me know in the future if you want any additional testing.

Tom

Devin,

Is it worth updating
(http://linuxtv.org/wiki/index.php/Hauppauge_WinTV-NOVA-T-500#Firmware) to
include some information related to having to use the patched source code if
using the .20 firmware?

Tom

Average users probably shouldn't be using the 1.20 firmware until the
patch is checked in to the v4l-dvb, so we can control which devices
use 1.20 and the new i2c functionality (based on actual testing).

My original plan was to keep everybody at 1.10 in the initial patch,
and once maintainers of individual devices tested 1.20, they could
submit a patch to make that the default for said device.  Patrick felt
strongly that 1.20 should be a drop-in replacement for 1.20, but based
on this evening's experience I'm thinking we should go back to my
original plan.

Honestly spoken I never tried the 1.20 firmware on the NOVA-T 500. (This 
card was last used in DiBcom 3 years ago.)

It might be that using the new i2c-requests along with the I2C-master do 
not work with some boards.

In that case you can still use the new i2c-requests but you need to select 
the gpio-bus instead of the i2c-master-bus.

Patrick.

Do you think we would need to use the gpio-bus for all requests within
the device, or only for talking to the mt2060?  If it's device-wide, I
can just add another flag to dib0700_state, otherwise I'm not sure
what I'm going to have to do here.
