Xbox One DVB-T/T2/C tuner

Hi all This looks like it could be very good value if Open Source drivers appear for it : http://www.xbox.com/en-GB/xbox-one/accessories/digital-tv-tuner#fb...

Hi,
I tend to agree with Benjamin, I think it is not the signal.

Using dvbv5-zap on monitor on a DVB-T2 mux with the main HD channels I get the following;

pi@raspberrypi:~ $ dvbv5-zap -c dvb_channel.conf "bbc two hd" -m > /dev/null

whereas a DVB-T mux tunes straight away

I'm waiting for the clearance/mux changes to occur on Sutton Coldfield. I can receive Waltham but that's pretty much useless as it's for the east & not west.

Benjamin Challinor

Ok, post retuning now the DVB-T2 mux at 602Mhz that has problems with this tuner has moved to a higher frequency and continues to have problems there (but as always it’s fine with the mygica T230). At 602mhz is a DVB-T mux now, and that tunes perfectly every time. Which shows that it’s not likely the tuner itself as it’s locking on to the signal in both cases. It seems the issue is more related to the demodulation. Another mux that was DVB-T and worked fine is now DVB-T2 and doesn’t work, back that up.

Interestingly, the only DVB-T2 mux that works fine is at a fractional frequency (.833). However changing the other muxes slightly doesn’t help

Hi, Since I upgraded the kernel as suggested I've not had any issues with reception, although as discussed it does take a while to lock.

I recently upgraded from a rpi2 to an rpi3 and i am getting a few crashes, maybe once every couple of days. Should I recompile? I need to reboot to fix it.

Oh no,
I upgraded the kernel (rpi-update), rebuilt, and it's doing this all the time now, as soon as I plug the tuner in.

Any suggestions?

Hi anthony

same problem here, can i go to an older kernel build?

Hi,
You can revert to the standard kernel with

sudo apt-get install --reinstall raspberrypi-bootloader raspberrypi-kernel

then rebooting.

according to https://github.com/Hexxeh/rpi-update you can revert to a specific kernel revision using a specific hash, for example;

sudo rpi-update b79886968bff850bbebd1f7d72ab5ac26803255e

should be reverting to 4.14.33 according to

https://github.com/Hexxeh/rpi-firmware/commits/master

My last build that crashed now and again was from 28/2 so that would be 4.14.22, assuming it was the kernel and not the dvb drivers.

How are you downloading the header files to compile? I seem to need to use rpi-source each time and it takes forever as it is downloading and unzipping lots of files. That said I was deleting them after I compiled, I've moved them to my external drive now I found the -d option!

Hi, Just in case this is helpful, I tried upgrading to stretch which has a 4.14 kernel by default. This gives the same behaviour.
I should say though that the stack trace when it crashes on boot is slightly different from what I posted above (I guess it isn't crashing sleeping)

I’m using kernel 4.14.32 without any crashes at all, on a pi 3b+. 2x tuners attached to a powered usb hub. Would recommend checking for power issues firstly - until I bought an official pi power supply I had random such issues even without an undervoltage warning.

Rpi-source is slow - however it’s actually quite reasonable if you buy an a1 rated sd card - they’re fast at small writes which are the key issue for use

Anthony Shephard

Okay,
I reverted to 4.14.32 and no change. Strange.
Maybe it's the supply, but I found a 2.5 amp charger which should be enough.
I suppose I could switch back to the Rpi2 as I never saw issues there.
Thanks for the help
Anthony

Benjamin Challinor

Pi 3 has a much higher power requirement, even without running the tuners off it as well, presuming that is what you are doing.

I found crashes with a pi 3 frequently of a 2amp charger - presume it just wasn’t quite stable enough to power it reliably continuallly.

Anthony Shephard

Just the one tuner but yes.
Anthony

Anthony Shephard

Well, Rpi2 crashed the same way, as soon as I plugged in the tuner.
I'm thinking maybe a new build on the Rpi2 might be the way forward.

Edit. Sorry I mean start a fresh with a new stretch image

Anthony

Anthony Shephard

Hi,
Well that crashes too. I've literally downloaded and installed a new stretch image onto a spare RPi2, built the drivers for the tuner, and used dvbtools to try to scan. Crashes as soon as the program accesses the tuner.

I don't know what else to try.

Anthony

Anthony Shephard

Here are my steps;


Downloaded stretch from https://www.raspberrypi.org/downloads/raspbian/
Rasbian stretch lite 350Mb
Unzip to get image
Then run win32diskimager and write to sd card

Per https://www.raspberrypi.org/forums/viewtopic.php?t=191252
Put a file called ssh onto the boot partition, so ssh is enabled. 
Ssh user pi, password raspberry

Then make and install dvb drivers
sudo apt-get install git git-man libdigest-sha-perl liberror-perl libncurses5-dev libproc-processtable-perl libtinfo-dev patchutils raspberrypi-kernel-headers

Download the xbox config file from
https://tvheadend.org/attachments/download/6361/PiXboxMBConfig.txt
And copy it to the pi via ssh
scp PiXboxMBConfig.txt pi@192.168.1.72:~/xConfig.txt
cp ~/xConfig.txt ~/media_build/v4l/

git clone --depth=1 git://linuxtv.org/media_build.git
cd media_build/linux
make download
make untar
cd ..
make distclean

Run "sudo make menuconfig", 
Wait for partial compilation to complete
<Load> xConfig.txt,
change remote support from M to * (select Y)
then <Save> as ".config" (note the leading period!) and then <Exit>.

make -j5
sudo make install
cd /lib/firmware
sudo wget http://palosaari.fi/linux/v4l-dvb/firmware/MN88472/02/latest/dvb-demod-mn88472-02.fw
sudo reboot

Reboot was okay, seems to be recognised

Hi,
It's definitely not hardware related. I went back to Jessie
http://downloads.raspberrypi.org/raspbian_lite/images/raspbian_lite-2017-07-05/2017-07-05-raspbian-jessie-lite.zip followed the same steps and it worked
(although I needed to download another firmware file too)

cd /lib/firmware sudo wget linuxtv.org/downloads/firmware/dvb-usb-dib0700-1.20.fw

I could not get stretch working, even reverting back to a kernel version 4.14.22 and an older version of media_build.

Anthony

Benjamin Challinor

Odd. I run stretch without any issues. It’s been upgraded from Jessie and wheezy before that and never had this issue.

Anthony Shephard

So I tried http://downloads.raspberrypi.org/raspbian_lite/images/raspbian_lite-2018-04-19

which is pretty recent. Maybe something changed??

I could try an older one, it just takes a little while :-(

Anthony

Anthony Shephard

Hi all,

I tried upgrading to kernel version 4.14.37 and that works fine!

Anthony
