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...

Thanks Crazy Cat!

Compiling now (takes 3 hours on raspberry pi), will post once I test this out.

And finally fixed DVB-T2 scaning with current V4L drivers :)

The T220A driver loads ok and everything looks good, but w_scan does not find a single channel - not from VHF (3 muxed DVB-T2) or UHF frequency (2 muxes DVB-T2, 4 muxes DVB-T). Another adapter on the same antenna cable finds them all. When trying to zap a channel, the FE does not lock.

$ dvbv5-zap -c ~/dvb_channel.conf -a 0 -I DVBV5 -o ~/test.ts -r -t 5 Yle\ TV1 using demux '/dev/dvb/adapter0/demux0' reading channels from file '/home/olli/dvb_channel.conf' service has pid type 05: 6001 tuning to 562000000 Hz video pid 512 dvb_set_pesfilter 512 audio pid 650 dvb_set_pesfilter 650 (0x00) Signal= 100.00% C/N= 0.00% UCB= 0 postBER= 0

Just to be clear, I tried with the patch you posted 2 hours ago (as well as the earlier one).

What am i missing here?

You are missing the firmware file dvb-demod-si2168-b40-01.fw and dvb-tuner-si2158-a20-01.fw. Download all si2168 and si2158 firmwares from here and copy them into /lib/firmware and try again.

Hi Crazy Cat,

I can confirm that the latest patches work ! I tested on a raspberry pi. The video was somewhat choppy, but I guess this is an issue with the pi. Hope these are merged into media_tree soon :)

Crazy Cat

Good :)

Hi Mark,

Can you tell me what you did to get the T220A (the one with Sony demod and TDA tuner) working? I took a recent media tree, applied CrazyCat's patches on top of that and compiled media build. Unfortunately I can't get a lock on any channel... Maybe I missed something here.

Cheers,

Thanks for that Olli - all up and running and playing on vlc now.
The next step of compiling this for OpenELEC on the Pi looks a bit tougher though...

Hi crazy cat,

On the pi I get a lot of continuity errors with the T220A, could this be related to the driver? On x86 it works fine

That is exactly what I did! With the second version of the patches, the tuner works but I get lots of continuity errors on a raspberry pi

I compiled the T220A driver again and now it works at least a bit better.

Here's an example on a VHF DVB-T2 channel:

Lock (0x1f) Signal= 90.26% C/N= 0.36% UCB= 238 postBER= 0

I believe the C/N ratio is not reported correctly in the stats, it's probably not that bad?

But, w_scan for example will only find about half of the muxes here:

DVB-T muxes:

3 of the 4 UHF muxes

DVB-T2 muxes:
1 out of 3 VHF muxes

1 out of 2 UHF muxes

Whereas from the same antenna socket an Si2168+Si2158 based device will find all of them.

Can someone confirm T220A/T230 will work with DVB-C?
Thanks.

Dont' think this patches against media_tree/master anymore. I used this instead of 0003-cxusb-Geniatech-T230-support.patch and rebuilt.

Seems to get it recognising everything again but I keep getting "bulk message failed" messages now though.

Crazy Cat

Geniatech T230 support patches, second+ edition :) + TS clock inversion implemented for si2168 (se)

patches against media_tree/master

Olli Salonen

The latest edition looks good to me. Will you submit to linux-media?

Deri James

Thank you very much, the Mygica T230 DVB-T/T2/C (aka August T210 v2) is now working perfectly for DVB-T and DVB-T2 (DVB-C not tested), previously DVB-T2 was throwing errors while playing, now perfect.

Tested using VLC in the UK. I believe you need to use the xspf format for the channels file because the old tzap channels.conf does not support DVB-T2 streams properly (it worked with the old PCTV 290 because that driver would attempt to open the stream as DVB-T2 if the DVB-T open failed, the newer modules do not do this.

yes :)

Kevin Panton

This is the error message I get when I try to build using the latest media_build. There seems to be an issue with the 0003-cxusb-Geniatech-T230-support.patch file.

Can anyone help me to solve this?

Thanks..
