Getting up and running with LimeSDR XTRX

roopa · 14 March 2024 09:47

I have couple of queries in integrating LimeSDR XTRX.

If we want to connect LimeSDR XTRX v1.2 board with PC/Raspberry pi, Which miniPCIe to USB adapter would you recommend, Since default adapters which are available in the market support only USB bus interface, not PCI-E bus type. As per XTRX HW spec, It uses PCIe bus internally, Correct me if I’m wrong.
Can we install Lime Suite via a package/installer (as per Lime Suite - Myriad-RF Wiki) or Do we need to build Lime Suite from source code (litepcie-update branch), as you mentioned in previous thread.
Can we follow Lime Suite source code build instruction from Lime Suite - Myriad-RF Wiki or Is there any updated build instruction for Ubuntu/linux ?

You cannot use USB for interfacing and must use PCIe. Fairwaves did sell a USB<>mPCIe adapter, but this was based on a chip which is now obsolete and I’m not sure how well it ever worked. Trying to tunnel PCIe over USB is a bad idea. Please use a proper PCIe interface.

If you need an SDR with a USB interface, I would suggest using LimeSDR Mini v2.

At this point you need to build from source using the branch specified.

It should be mostly the same to build, with one major difference: you will also need to build and install the PCIe kernel driver:

Documentation that covers all of this is being worked on and should hopefully be ready in the next week or so.

Thank you Andrew!

We have our own form factor which has mini PCIe port, but porting driver into hardened OS what we are using, is quite a challenge. So we are looking for form factor which supports LimeSDR XTRX. Do you have any such thing ?. I was wondering how others are porting XTRX into their PC without using any adapter.

I would appreciate your help!

If one lane of PCIe will suffice there are various off the shelf options, usually small form factor and industrial PCs, that have an mPCIe slot.

If you need two lanes you will need a custom design. We will soon be offering a full size PCIe to mPCIe adapter board, that has two lanes and an integrated RF front-end. If you’re signed up to the LimeSDR XTRX campaign you should be notified once this becomes available.

roopa · 22 March 2024 02:05

Thanks you Andrew!

I signed up to the LimeSDR XTRX campaign. May I know the documentation for building LimeSuite and other XTRX related driver support is ready ?, Since you mentioned in the previous thread that, it will be ready by this week.

andrewback · 22 March 2024 12:26

It’s being published here, but still very much a work in progress:

https://limesuiteng.myriadrf.org/

This gets rebuilt whenever the development branch is merged into stable. If you want to get the very latest docs you would need to track the develop branch in:

And either build the docs yourself, or just read the reStructuredText files that the docs are built from.

roopa · 5 April 2024 02:42

Hi Andrew,

Can you share us the documentation to build pcie-linux-module and it’s stable branch ?

Thanks,
Roopa

roopa · 5 April 2024 03:46

Hi Andrew,

This is regarding LimeSuite GUI. Since we are trying to bring-up LimeSDR XTRX in a our form-factor which doesn’t have display, Can we skip LimeSuite GUI from building Limesuite Bundle ?

Thanks,
Roopa

ricardas · 5 April 2024 05:18

Hi roopa,
GUI is optional and will not be built if wxWidgets libraries are not installed, or -DENALBE_GUI=off option is passed to cmake.
The pcie linux kernel module is now integrated into LimeSuiteNG repository and will be built/installed along other components. It just needs to have linux-kernel-headers package installed.

I tried to install LimeSuiteNG with develop branch using below commands.

git clone https://github.com/myriadrf/LimeSuiteNG
cd LimeSuiteNG
git checkout develop
sudo ./install_dependencies.sh
cmake -B build && cd build
make -j24
sudo make install

But still not working with SoapySDR…

$ SoapySDRUtil --find

Also, The Soapy LimeSDR Source not working on GNU Radio.
Is it still in development?

ricardas · 15 April 2024 10:50

Did you install CubicSDR from packages, or compiled it from Source?
There seems to be problems with using SoapySDR, the packages might install old plugin version wich is linked to old LimeSuite. I’m looking into sorting it out.

Meanwhile, you can install gnuradio-dev package, and compile LimeSuiteNG with cmake ../ -DENABLE_GNURADIO=on , that will build a gnu radio plugin, and gnu radio companion will show “LimeSDR Source (RX)” and “LimeSDR Sink (Tx)” blocks.

markpaz · 16 April 2024 11:37

Thank you for your reply.
I remember that CubicSDR was installed from apt.
I will try to re-install some packages this weekend with your comment in mind.

Thank you!
Facing build error while building LimeSuiteNG, Here the details go on…
I tried to build LimeSuiteNG from develop branch using the below commands.

git clone GitHub - myriadrf/LimeSuiteNG
cd LimeSuiteNG
git checkout develop
sudo ./install_dependencies.sh
cmake -B build && cd build
make -j32

What Linux version are you using, the The C compiler identification is GNU 9.4.0 is quite old.

roopa · 24 April 2024 08:16

I’m using Linux version : 5.15.0-101-generic.

ricardas · 24 April 2024 08:43

That’s the Linux kernel version. What distribution is it, like Ubuntu, NetBSD, ArchLinux…
you can run command uname -a to get the info.

Please attach the full build log, because you are running the make -j32 it is compiling in multithreaded mode, so the error messages are scattered in the log.

Or you can try to compile just the failing module make litepcie-kernel

old linux distributions compiler defaulted to C89 standard. I’ve added flag to specify newer standard, so now should work for you.
