Af9015

[arnebaier]

Hi, I am trying to get an AfaTech AF9015 chip (USB stick) up and running, but mythbuntu doesn't seem to recognize it as a DVB-T source. Who can help?

[mvirkkil]

The chip AF9015 is not supported yet.

As you might know the linux-dvb project develops support for different DVB-chips. One of the people working on it has created a driver to support the AF9015 chip, and you might be able to use it. The sourcecode for the driver can be found in his mercurial repository at http://linuxtv.org/hg/~anttip/af9015/ and the firmware is at http://otit.fi/~crope/v4l-dvb/af9015...irmware_files/

Please note that getting this to work means you probably need to get the development version of the linux kernel dvb subsystem, patch it and compile it.

Eventually the support will probably get in to linux-dvb and Linux in general but at the moment getting the AF9015 to work is a bit challenging.

So once I run "make install" on the downloaded files mentioned above, will the tuner automatically be recognized in mythbuntu or any other media center?

[mvirkkil]

What I did to get it working was (iirc):
- download and extract sources from http://linuxtv.org/hg/~anttip/af9015...d1798b.tar.bz2
- compile, you need at least the build-essentials and kernel-headers packages, you will find the compiled kernel modules (*.ko) in the v4l directory
- remove any dvb or v4l kernel modules you currently have loaded in your kernel (lsmod and "modprobe --remove")
- insert the newly compiled modules in to your kernel "sudo insmod ./v4l2-core.ko" etc.

I don't exactly remember which modules I loaded to get it to work. If you get any error like undefined symbol, check dmesg for more information. What I remember is that I needed to modprobe i2c-core, and to insmod at least dvb-usb. the af9013 -frontend and mt2060 and maybe qt1010. Oh and of course af9015. I also added a bunch more because of dependencies revealed by "undefined symbol" messages.

You also need to place the firmware file in /lib/firmware

@mvirkkil

So you got a tv tuner with af9015 to work??? great!
what is the usb id of your tuner (obtain e.g. with lsusb?)
cheers

[motumboe]

I'm trying to get it working on a Terratec USB T XE tuner but at the moment without success.
USB ID 0ccd 0069

[mvirkkil]

Install at least the following packages
build-essential
linux-headers-generic
dvb-utils

- Download the firmware to /lib/firmware/dvb-usb-af9015.fw
- remove any loaded v4l and dvb modules from your kernel
* first check what modules are loaded by issuing 'lsmod'
* remove modules by calling modprobe --remove modulename
ex: 'sudo modprobe --remove v4l2_common'
* if you get the error message "FATAL: Module v4lsomething is in use.", check which module is using it, and remove that one first.

- Download and unpack af9015-ca6a41d1798b.tar.bz2
- go to the af9015-ca6a41d1798b directory
- run `make`
- go to the subdirectory v4l (typing ls *.ko should show a whole bunch of kernel modules)
- 'sudo modprobe i2c-core'
- 'sudo insmod ./dvb-core.ko'
- 'sudo insmod ./dvb-usb.ko'
- 'sudo insmod ./mt2060.ko'
- 'sudo insmod ./qt1010.ko'
- 'sudo insmod ./af9013.ko'
- 'sudo insmod ./dvb-usb-af9015.ko'

Note: If you get something like "symbol not found (-1)" while insmod:ing the modules, check dmesg for the details and try to figure which module you are missing.

When you input the usb stick you should see the following messages:

Ok, so next you will need a channels.conf file. To generate it you should use the command (replace xx-CityName with something more suitable):
'scan /usr/share/doc/dvb-utils/examples/scan/dvb-t/xx-CityName > channels.conf'

I haven't tested it very heavily, just by using xine. I couldn't get the radio channels to work in xine so I simply removed them from the config file.

To test it with xine copy the channels.conf file to the .xine directory. Start xine and press the dvb button.

There is currently no support for the remote controller, so I have not inserted the modules that the remote would use (probably ir-common.ko and ir-kbd-i2c.ko).

'lsusb -v' shows the following info about the stick:

When trying to install af9015-ca6a41d1798b (or v4l) I'll get:

And that "Virhe" is Error...

[teetee]

And by the way, from where can I found firmware that is needed here?

http://otit.fi/~crope/v4l-dvb/af9015...irmware_files/
Won't open...

Edit: And should that firmware be located at /lib/firmware/dvb-usb-af9015.fw before starting to do anything else?

mvirkkil,
thank you very much for your really detailed explanation! This evening I'll try it!
Thank you again,
Marco
