Hello
I have Matrix ARM mini PC + TBS7220 mini PCIe DVB-C Tuner card.
How could I prepare the driver for this card on Matrix ARM mini PC?
Thank you

Please fix the driver for recently released kernel 4.9 for debian linux.

this issues related to some new features in 4.9 kernel
https://github.com/LibreELEC/LibreELEC.tv/pull/1076

So wait fixes in main-line media_tree (dvb-usb related) or recompile your 4.9 kernel with disabled disable vmapped stack.
Or better use LTS kernel like 4.4

Hi everybody,

A few months ago, I spent many hours to try to fix lirc. I soon as I installed TBS driver, it broke lirc_serial. I need lirc_serial because I use an IR receiver on serial com 1.

I read this post but situation isn't enough clear, sorry ! Could you please summarize :
- is it possible to use lirc with TBS driver ?
- If so, under which kernel, and with which version of TBS driver ?

Thanks a lot !
Regards.

Look at my answer in this thread from Friday Jan 13. (you will find them at Page 8).

I use also a remote control with an ir-receiver at COM1 for many vears with "lirc_serial" at my HTPC.
With one of the last update of the "new open source" driver from TBS they have changed from "lirc_serial" to the new "serial_ir"!

You can use "serial_ir" instead of the old "lirc_serial", without any changes at your remote control, your lircd.conf etc.
You have only change/add 2 files to use the new "serial_ir" and that is very easy.

Paul

this general kernel changes, not related to dvb drivers

Sounds great !
I will try this driver, I hope my TBS6928 (with CI) will be supported.

Thanks !

supported, but need 4.4+ kernel for saa716x module

crazycat Wrote:supported, but need 4.4+ kernel for saa716x module

OK. Then I will try on Linux Mint 18.1 (kernel 4.4.0.x) instead of Debian 8.7 (kernel 3.16).
Thanks fort the tip.

1. In /etc/modprobe.d I added a new file called "serial_ir.conf" with this content:

#COM1 equivalent, /dev/ttyS0
options serial_ir irq=4 io=0x3f8

2. In /etc/lirc I changed the file "hardware.conf" and replace "lirc_serial" with "serial_ir" :

...
REMOTE_MODULES="lirc_dev serial_ir"
REMOTE_DEVICE="/dev/lirc0"
...

After a reboot I can now use my remote control and all things work perfect!
I used an needed the new open sorce driver with my new TBS-6205 to receive DVB-C and DVB-T2 with on driver at the samt time!

Very good work from your team!

Paul

Can you explain how you can get dvb-c and dvb-t, on tbs6205 at same time?
I did that, using osource drivers, and work, but the signal is very week, this card as only one input, so i had to combine both modulations on same input.
Is thare any chance to have this working 100% on this way? I can only have on card on this system.

In the past i used one 6205 in dvbc and 6281 in dvbt and every thing worked perfercly, but on this system can only have one card.
Is thare any way to modify the card to use rf out as rf in??
