Farsync hardware

[Pascal Charest]

Hello,

We've received a few questions recently about Farsync hardware. Here is
some information that can be useful to you if you are using this piece
of hardware.

We have added a new section on the CRC-DABMUX web page about the Farsync
hardware installation. This new instructions were tested on Ubuntu 11.10
and 12.04. The test was successful on 11.10 (kernel 2.6.38), but not on
12.04 (kernel 3.2). Current version of Farsync drivers are not
compatible with 3.x kernel. Once a version of Farsync drivers that is
compatible with 3.x kernel appears, the same procedure can be followed
as long as the API is backward compatible. Depending of your Linux
distribution, kernel version, Farsync drivers version, some compilations
issues not listed on the web page might happen. We'll improve the list
as people find issue/solution.

Regards,

Pascal

Hello,

I'm reading instruction on CRC-DABMUX section
Extract and change to farsync driver source directory. Install the OEM version (default).
> sudo ./install oem
> sudo depmod
- Make sure that the line install farsync.ko went well and that there is message such as cannot stat farsync.ko.
- It is very important to reboot after successfully installing the driver.
Possible issues:
Missing kernel source or headers
sudo ln -s linux_headers-`uname -r` /usr/src/linux

I can't install driver.
I have symbol link inside /usr/src/
lrwxrwxrwx 1 root root    34 2013-02-12 17:31 linux -> linux_header-3.0.0-19-generic-pae
drwxr-xr-x  7 root root 4096 2012-05-02 15:34 linux_header-3.0.0-19-generic-pae

sudo ./install oem
I had message

    Farsync WAN/OEM driver for linux installation
    Cannot find /usr/src/linux
    PLease make a symbolic link callad /usr/src/linux to where your
    Kernel Source tree or Kernel Header files are located.
   
What is problem ?

[Brendan Kehoe]

Hi,

Francois, which version of the Farsite driver are you trying? If you're trying an older version such as 1.09 then its not compatible with Linux 3.xx kernels and you need 2.9.32 (newest supported). I've been unsuccessful in using the newer version 2 Farsite drivers with DabMux. 

I meant to post a few weeks ago about this but I noticed that Farsite have a newer driver (version 2.xx which supports the version 3.xx Linux kernels) and myself tried to get it set up but I was unable to incorporate the new farsite library into CRC-DabMux, with DabMux failing to compile. I'd integrated the new library from the 1.09 Farsite driver on many occasions before successfully. 

It'd be nice to be able to upgrade my Linux versions by being able to run the latest Farsite drivers so if anyone else has any thoughts or ideas they'd be appreciated.

Cheers, Brendan.

It's working with
  Ubuntu 11.10
  FarSync drivers version 2.0.3 for Linux
There is a error with explications
Read => http://mmbtools.crc.ca/content/view/39/65/
        At this line

            Missing kernel source or headers
            sudo ln -s linux_headers-`uname -r` /usr/src/linux

        The good instruction is
            sudo ln -s linux-headers-`uname -r` /usr/src/linux

Actually my test script is :

CRC-DabMux -L "Label MUX" \
-F output1.dab -k -b 48 -i 1 -p 3 -S -L "Radio 1" -C -i1 \
-F output2.dab -k -b 48 -i 2 -p 3 -S -L "Radio 2" -C -i2 \
-F output3.dab -k -b 48 -i 3 -p 3 -S -L "Radio 3" -C -i3 \
-F output4.dab -k -b 48 -i 4 -p 3 -S -L "Radio 4" -C -i4 \
-O file://out.eti -O simul://

So now I would to send output CRC-Dabmux towards output farsync.

I think it's something like this

CRC-DabMux -L "Label MUX" \
-F output1.dab -k -b 48 -i 1 -p 3 -S -L "Radio 1" -C -i1 \
-F output2.dab -k -b 48 -i 2 -p 3 -S -L "Radio 2" -C -i2 \
-F output3.dab -k -b 48 -i 3 -p 3 -S -L "Radio 3" -C -i3 \
-F output4.dab -k -b 48 -i 4 -p 3 -S -L "Radio 4" -C -i4 \
-O fifo:///dev/sync0

How do I know output name farsite ? (/dev/sync0/ ??)
How do I know which output connector card farsite use ?

Thank you

[Brendan Kehoe]

Hi Francois,

So you have more than 1 Farsite card? There is only one output connector (marked 'T') on the TE1 card.

Did you not so the API update by the way - that is the part that I couldn't get to work with the v2 Farsite drivers. This was essential in the past anyway.

I used one Farsite card, I find output connector  (marked T)
I did this

    tar -zxvf farsync-2.0.3.tar.gz
    ./install oem
    sudo depmod
    sudo ln –s linux-headers-`uname –r` /usr/src/linux
    cp farsync-???/include/farsync.h crc-dabmux-???/lib/farsync/
    cd /home/…../crc-dabmux
    make clean
    make
    make install

Did you change the question marks with package version that you are using?

The scheme for ETI card is not fifo, but raw. See URL section in
CRC-DABMUX documentation for more information.

To get the name of the device, run command 'ifconfig -a'. This will list
every network interface on your computer, including regular ethernet and
the G.703 interface. Device name should be hdlc0 (for Cyclades) or sync0
(for Farsync). Then, the output option should look:
-O raw://sync0

Output connector is identified as T.

Hope it will help you,

Pascal

So, the device is really sync0.

These error messages are from CRC-DABPLUS. It will help to have only
CRC-DABMUX output. Here is a simple command that can do the job (no audio):

CRC-DabMux -T -S -C -O raw://sync0

But I suspect that the problem is that you don't have sufficient
permission. Usually, only root has access to raw network device
interface. Try to run the precedent command with administrative privilege:

sudo CRC-DabMux -T -S -C -O raw://sync0

Regards,

Pascal

[François Picard]

I'm running this command

Can you compile CRC-DabMux with debug symbols and run it under the
debugger? It will give the line where it crashes.

To compile with debug symbols, remove the --disable-debug option with
configure. Do a 'make clean' before the make.
To start under the debugger, run 'sudo gdb --args CRC-DabMux -T -S -C -O
raw://sync0 ' and press 'r' and <enter>.

Thank you,

Pascal

Thank you for taking the time. It seems that that the information is
still the same. Can you write bt <enter> in gdb once the application
crash? I hope to get more details with the backtrace, detail such as the
source code line where it crashes.

Thank you,

Hum... this one looks tricky. It is some kind of stack overflow.
Probably this happens with an ioctl get function with a driver different
than the one that that I've used. The API might have slightly changed.

Which OS are you using? (ex: Ubuntu 12.10)

Are you using an unmodified version of CRC-DADMUX 0.3.0.4?

Pascal

[François Picard]

Hello,
I used Ubuntu 11.10, kernel 3.0.0-19.
For use a old kernel, I have to install a new ubuntu version.
Have you got a best solution ?

As far as I can tell the install is now complete and you should be able to
start the farsync driver with the following command

   /etc/init.d/farsync start

You may need to load the required WAN modules first.
See the Post Install Instructions in the install document to
find out how to load and unload them with the farsync driver.

If this does not result in the driver being loaded then please
consult the Trouble Shooting Guide.

Finally you will need to configure the new synchronous network interfaces.
See the Install documentation for more details.

When we read those lines we don't know if the installation has done or not.
Can you help us about this point ?

I see compilation problems in the output.

My work office and lab were recently moved. I currently don't have any
system with the FarSync card, only for USRP.

Is there anybody on this mailing list able to help with FraSync card?

I've never tried the 2 driver serie, only 1.09 driver serie.

In the ifconfig output, do you have anything else than eth, waln or lo?

Hum, looking at the date of my previous message, it is definitely not
2.03. As mentionned in my previous message, I don't have a system with
the FarSync and can not validate my answer, but I'm pretty confident
that it was 1.09.05-02.

I've looked on the web page of 2.0.3 version and it is not mentioned
that the API have changed. So my guess is that it should work. As usual,
there might be some minor tweaks required in order to make it works. YMMV

Pascal

[Brendan Kehoe]

The 2.xx driver works perfectly with CRC-DabMux assuming one updates the farsync.h file as with the 1.09.05 version, albeit I've only been running it on Ubuntu 10.04 - haven't been around the machine to try upgrade it to a newer version since the new Farsite drivers supporting the 3.xx kernels have been released. 

Pascal

[Pascal Charest]

Thanks a lot Brendan for the information.

[Sylvain LATU]

Hello,
I am currently conducting a DABMUX DABPLUS and installation.
I use Ubuntu 11.04 with Kernel 2.6.38-8.
To complete my installation, I took a TE1 FARSITE.
Is this a good choice?
I installed the 2.0.3 driver as I previously saw DABMUX was compatible.
How can I send data through the TE1 with a script ?
And could I adapt the output stream?

Regards,

Sylvain LATU
