August DVB-T210

Hi. Was wondering if this was compatible with tvheadend as there's not much information from users about this device. Does anyone have one? Is it working wel...

Curiosity:
In source:
http://git.linuxtv.org/cgit.cgi/media_tree.git/tree/drivers/media/dvb-frontends/si2168.c
write the firmware version, but for me nor in kern.log nor is dmesg does not appear.

Hello Olli!

I located the problem Antti Palosaari. Here
http://blog.palosaari.fi/2014/04/naked-hardware-15-pctv-triplestick-292e.html?showComment=1422969618077#c812668636235109288

He recommended to you. In the linked blog is fresh information.

What can I do about it? (debug, sniff etc.)

Thank you in advance for your help!

Olli Salonen

Hi Kornel,

I have the device and even if I did not add the support for it, I could have a look. I'm just a bit short in time now and I have only DVB-T/T2 broadcast available here (it works fine). I'll try to setup my modulator for DVB-C QAM256 and see if I can see the same.

If you've got the possibility, it'd be great if you could take a full mux dump and tell me the exact parameters of the channel that you use so I can replicate that in the modulator. Maybe this happens always, so it's not necessary, but the closer I'm to your setup the bigger the chance that I'll see the problem.

There's some discussion about full mux dump:

https://tvheadend.org/d/1179-what-exactly-does-the-full-mux-reception-do-when-enabled

Just to confirm, you do see the issue with different software as well? For example, if you you dvbv5-zap to tune to a single channel it's sometimes faulty?

Kornél Papp

Hi Olli!

I make dvb_channels.conf with dvbv5-scan tools.
With "dvbv5-zap M1 -c dvb_channel.conf -o M1_3.ts -t 10" command make a file but can not play with vlc.
I linked the verbose dvbv5-scan tools output (with error and with errorless.

And I can not make a full mux dump according to this:
https://tvheadend.org/d/1158-sample-muxdumps?r=10187#message-10187
in mux window on play push left button and "save link as" but only saving a m3u file.

Succeeded make a full mux dump with error. In m3u file the network link copy to vlc which save file.

Kornél Papp

This is error less dump!

Hello.

I've got 2 of these. Which appear to be the Augut DVBT-210v1 (a.k.a, Geniatech T220). With a recent version of tvheadend-unstable. On ubuntu-14.10.

They correctly identify on dmesg. And I can see them working both in linux on the cmd line (w_scan) and also tuning in Tvheadend. However neither method does it pick up any of the DVB-T2 HD channels in UK. So how do I get the HD working for this (the v1) device?

Many thanks.

Is this ^^ the correct patch for v1 Geniatech-T220 ? To enable HD T2 hide channels? w_scan gives CRC garbage data error on any T2 muxes. I am using ubuntu 14.10, kernel 3.16.0.31.

It works for Standard def. But not the Hi-def.

Ah right. Ubuntu 14.10 remains on the previous 3.16.* kernel. Which did not get the media tree changes for T2 hi-def support on the Geniatech T220 (august DVB-T210v1). That same situation may continue the end of April 2015. When 15.04 comes out to replace it.

But before then, I can install a newer kernel on my existing ubuntu 14.10. As a 2nd, 3rd boot menu entry in GRUB2.

[EDIT]

Upgraded my kernel from 3.16 ---> 3.19 on ubuntu from official ubuntu pre-release kernel sources. And now w_scan picks up the HD channels… it worked! No need to re-compile media tree or anything like that. Many thanks.

I get error -22 with latest media_build for Ubuntu 14.04 x86

But applying the patch like here:

> wget --no-check-certificate https://patchwork.linuxtv.org/patch/27777/raw/ -O backports/t230.patch

> sed -i 's/add api_version.patch/add api_version.patch\nadd t230.patch/' backports/backports.txt

and then ./build gives me:

Applying patches for kernel 3.13.0-49-generic
patch -s -f -N -p1 -i ../backports/api_version.patch
patch -s -f -N -p1 -i ../backports/t230.patch

Not need any patch, Geniatech T220,230 support included in official V4L DVB media_tree (and kernel 3.19+)

Following up on Crazy Cat's post... Just installed the 3.19.3 kernel on a Ubuntu 14.04 server and the August DVB-T210 stick (recently purchased, so is "version 2" - equivalent to Geniatech T230) appears to be recognised and working OK in tvheadend 3.9 without needing to mess around with V4L etc. (V4L can be a pain to compile and install as I have found that the latest V4L code changes frequently and is not always in presented in a compilable state.)

The DVB-T210 stick comes up in the "TV Adapters" tab of tvheadend as "Silicon Labs Si2168" with DVB-T & DVB-C devices. If using just off-air TV the DVB-C device can be left disabled. DVB-T2 HD channels on UK Freeview service working fine. :)

i tested thus combinations so far:

stock kernel: device not detected at all
stock with media_build: detected but error -19 & -22
kernel 3.19.3 from ubuntu repo: not detected
kernel 3.19.3 and media_build: not detected

kernel 4.0rc7 from ubuntu repo: error -22

Hi Crazy Cat, any news on the inclusion of tda18273 driver into the media tree?

Oliver Thomas

I've finally got round to trying my Geniatech T220A USB tuner again but haven't managed to get very far.

I'm trying to set it up on an old O2 Jogger running Xubuntu 14.04 (3.2.58 kernel). I have previously used this device (without any issues) with 2x Hauppauge USB Nova-T DVB-T sticks through a USB hub and TVHeadend v3.4.28.

As far as I understand it I need to:

1, download the following firmwares and place in /lib/firmware:
https://github.com/OpenELEC/dvb-firmware/blob/master/firmware/dvb-demod-si2168-02.fw https://github.com/OpenELEC/dvb-firmware/blob/master/firmware/dvb-tuner-si2158-a20-01.fw

https://github.com/OpenELEC/dvb-firmware/blob/master/firmware/dvb-demod-si2168-b40-01.fw

2, download the following patch for the T220A:

https://tvheadend.org/attachments/download/2389/0002-dvb-usb-dw2102-Geniatech-T220A-support.patch

3, download and build media_build using the following commands (inserting relevant patches into the command prior to ./build):

git clone git://linuxtv.org/media_build.git
cd media_build
./build
sudo make install

sudo reboot

Do I need to add a command for the T220A patch whilst building media_build to apply the patches?

Am I missing anything here? Do I need to re-compile my kernel with 'CONFIG_I2C_MUX' and if so, how would I do this?

The O/S was specially made for the O2 joggler downloaded from here:

http://joggler.exotica.org.uk/ubuntu/

If anyone can help with this I would greatly appreciate it. The O2 joggler would be an ideal TVheadend server; it's very low power, has gigabit ethernet, seems rock-steady and is contained within a tidy little unit.

1. This firmwares for T230 and another Silabs-based devices.

2. + TDA18273 tuner support patch - https://tvheadend.org/attachments/download/2388/0001-tuners-tda18273-silicon-tuner-driver.patch

3. not need i2c mux support

Oliver Thomas

Crazy Cat, thanks for the reply.

1, Should I use those firmwares or not?

2, So I will use:

https://tvheadend.org/attachments/download/2389/0002-dvb-usb-dw2102-Geniatech-T220A-support.patch

and

https://tvheadend.org/attachments/download/2388/0001-tuners-tda18273-silicon-tuner-driver.patch

Is this the method to apply these patches?:
"to add a patch copy the .patch file to the backports directory, and add the patch file as a line to the {kernel-version}_series file in the packports dir."

Crazy Cat

1. T220,220A not need any firmware.

2. hmm, i must check it later :) usual i work with full git tree

Oliver Thomas

Crazy Cat:

2, How would you do this with full git tree?

Sorry for all the questions but thanks for the help! :)
