Open Source Driver with TBS 6285

[drphilth]

Hello,


I am having a problem with the TBS Open source driver on my TBS6285. The driver compiles and loads correctly, but I cannot tune any channels.

I'm running Ubuntu 16.04.3 with kernel version 4.4.0-96-generic.
I am in the UK and trying to view free-to-air DVB-T and DVB-T2.

An old version (I'm not sure how to find the revsion, but seems to be from Dec 2015) of the ljalves open source driver works well on my hardware, so I don't think it is a hardware problem.

w_scan tells me "Info: no data from PAT after 2 seconds" when I try to scan channels.

TVHeadend log shows this:

maybe you not set bandwidth 8MHz ?

[drphilth]

maybe you not set bandwidth 8MHz ?

w_scan checks both 7Mhz and 8Mhz. I get no results on 7Mhz (naturally). When searching 8 MHz it finds the muxes, but fails to tune them with the above error.

[smile]

Hi
using the new driver, you need specifies the mode (DVBT or DVBT2)of the current frequency.

Best Regards

[PeteM]

This appears similar to an issue with the TBS6285 that I reported on github: https://github.com/tbsdtv/linux_media/issues/79

When I was investigating I also used dvbv5-scan from dvb-tools as well as mythtv-setup to exercise the tuner. Both of these take configuration for the multiplex so you don't get config discovery issues.

As a short term fix I ended up patching the old TBS official drivers so that they build and install with kernels 4.13.x. The old drivers work for me.

Hi smile,


How do we do this - I can't find it in the docs for the driver? Is it an option the driver is expecting to receive from the application?



Thanks

[drphilth]

OK, I've done some more debugging.

With my old, working driver, I generated an initial scan file from w_scan. I noticed that the DVBT2 channels didn't have a valid bandwidth set, so I manually edited it to be 8MHZ.

I was able to successfully use this file with my old (ljalves) driver to generate a channels file with dvbv5-scan. Having generated this file, I was able to tune channels with the old driver using dvbv5-zap

I then compiled and installed the more up to date tbs open source driver. I cannot tune channels with dvbv5-zap. When I try to run a channel scan I get this output:

Any ideas on where to go from here? As far as I can see, I am correctly specifying the DVBT / DVBT2 type and I have set the bandwidth correctly.

Here's the working version of the drivers:

https://www.dropbox.com/s/o9ohj3ljeke9u ... g.zip?dl=0

Still compiling against kernel 4.4.0-97-generic on ubuntu server. I have no idea if it will compile against anything newer than that.

dvbv5-scan output from the working version of the drivers. I've removed the full list of services, for brevity:
