FMCOMMS5/ZCU706 on remote GNURadio

Hi Diogo,

The IIO blocks (including the ones for the FMCOMMS5) are already provided by GnuRadio 3.10, so there shouldn't be anything to install aside (as I understand you manually installed gr-iio in /usr/local/lib/python3.10/dist-packages). You only have to install the "libgnuradio-iio3.xxx" package and you should be good to go.

Cheers,

Hi,

Thanks for the response. By checking the installed packages, the one you mentioned is already installed. Is there anything else I must do?

I also add t the python3 Path the directories where the packages would be found:

I am really confused on what to test next. I already tried installing from GNU Radio and IIO Devices: gr-iio [Analog Devices Wiki] but it does not work. Just to clarify again. I am trying to setup a remote connection to a ZCU706 with and FMCOMMS5 running Kuiper linux, from a WSL2 Ubuntu running on a windows PC. I want to design on gnuradio on WSL2 and then run directly on the WSL2 but getting the data from FMCOMMS5. 

I think you installed gr-iio and it conflicts with the libgnuradio-iio package that you installed with the package manager.

What I would try, is uninstall gnuradio and libgnuradio-iio, remove anything related to gr-iio in /usr/local, and install gnuradio again.

I will try that. Thanks for the reply! 

To ensure that everything was removed, I performed a new installation of the WSL2 Ubuntu. Then I used $ sudo apt install gnuradio to install gnuradio as it is said in the gnuradio page. Then tried to use the gnuradio with the FMCOMMS5 source block and the same error appears. When using the FMCOMMS2 source block it only says that the device was not found (as expected since I have only the ZCU706+FMCOMMS5). The following image shows the output of both scenarios:

I also checked if libgnuradio-iio was installed and it was.

Could you share your FMCOMMS2_test.grc?

Since the file cannot be uploaded here, you can use this link: https://we.tl/t-EziOiFO8SX

If you only want to see the blocks I am using, this image shows:

Sorry for the delay. Because the .grc file could not be uploaded here, I pasted a wetransfer link and got blocked from sending a reply in this post. This is a second account since the other is blocked.

Regarding what you asked for, if you really want the .grc file tell me other way to sent it to you. In the mean time, I'm only using an FMCOMMS2/3/4 source block connected to a QT GUI Time Sink or an FMCOMMS5 connected to a QT GUI Time Sink

Hi Diogo,

Sorry about that. Looks like your account was unlocked though.

We are debugging it, it looks like at some point the some of the code for the FMComms5 blocks was accidentally removed in the upstream GNURadio project.

Sadly, this means that once we fix it you will have to compile GNURadio from sources to have the fix, because the next release most likely won't happen soon.

Hi,

Thanks for the reply.

Do you know how much time it will take to get the fix available on github? When you say compile from source, it means to follow the tutorial present here https://wiki.analog.com/resources/tools-software/linux-software/gnuradio?

Is there an older version I can use in the mean time?

We'll try to have a fix today and send a pull request to GNU Radio.

By "compile from source" I mean compiling https://github.com/gnuradio/gnuradio (the tutorial you pointed to was for use before gr-iio was merged into the upstream GNURadio project).

Sadly the IIO blocks were added to GNURadio 3.10.0 and FMComms5 support is already broken in this version; so even if there was a point in history where they were present and working, there is no released version that supports it properly and you would have to compile from sources anyway.

Cheers,

Ok, thanks for the clarification. Is it possible to notify me when the fixed source code for gnuradio is available?

Thanks,

Diogo Baptista

Of course.

Hi,

I am running GNU Radio 3.11.0 installed from source, and I have the same issue with fmcomms5. Any update about the fix and the pull request?

Thanks,

Ennio

I am working on it:

GitHub - analogdevicesinc/gnuradio at fmcomms5

But I don't think it works yet - and it doesn't help that I don't have the hardware to test with.

Cheers,
