USRP E312 (AD9361) - IIO Oscilloscope doesn't work

Hi Rémi,

Could you try to install libserialport via the package manager rather than building it  from source ? 

Try :  apt-get install libserialport-dev

After you have installed this package, you will need to rebuild libiio with the serial backend enabled. Then, you will also have to rebuild iio-oscilloscope.

Let us know if this works for you.

HI csuteu ,

Thank you for your reply.

I installed as you said libserialport-dev. But I get exactly the same error.

Here are the results of some commands if you need them:

Do you have any other possible solutions to this problem?

I also tried to install IIO oscilloscope with this link on a windows laptop but I get the following error:

Is there any other software to install or is the problem with the USRP E312?

Thank you very much,

Regards,

Rémi

Hi RemiL ,

You will have to set XPAR_XUARTPS_0_INTR in the following define:

https://github.com/analogdevicesinc/no-OS/blob/d4a97230dc27d5a3c6d243d18e424fef6da73c93/projects/ad9361/src/parameters.h#L107

then, you should be able to connect with osc to the system.

Regards,

George

Hi danmois ,

Thank you for your reply.

I tried to replace XPAR_XUARTPS_1_INTR by XPAR_XUARTPS_0_INTR in the define L107

of the file parameters.h but i get exactly the same errors as before on WSL and Windows.

Have I forgotten something? How can I solve this?

Thank you,

Regards,

Rémi

Hi, Rémi.

If you'd like to retry building libserialport from source on your Ubuntu 20.04 machine , these are the steps that you need to follow:

1. Install the packages required by autotools:

sudo apt-get install autotools-dev autoconf libtool

2. Clone the libserial port repo and build the library:

git clone https://github.com/sigrokproject/libserialport.git

cd libserialport

./autogen.sh

./configure --prefix=/usr

make

sudo make install

This should get rid of the initial "inappropriate ioctl for device" error that you have reported.

After you have built it, you can proceed to rebuilding libiio with the serial backend enabled and finally, rebuilding iio-oscilloscope.

We hope this fixes your issue and you'll be able to connect to your device.

-Cristina

Hi csuteu ,

Sure, I can do that.

However, I get stuck when I try to execute the command ./autogen.sh

I have the following error:

/path/to/libserialport$ ./autogen.sh
/bin/sh: 0: Illegal option -

Do you know how I can avoid this mistake?

Thank you,

Regards,

Rémi

Is this the entire error message ? If not, could you include the complete error ?

Are you running Ubuntu natively or through Windows WSL? 

What shell are you using ? What is printed when you type echo $SHELL ?

Yes, this is the complete error.

I'm on Windows WSL (Ubuntu 20.04, Kernel 5.10.102.1, Windows 10)

The result of echo $SHELL is /bin/bash.

Regards,

Rémi

Hi  csuteu ,

I've managed to solve the SHELL problem.

The problem of ./autogen.sh comes from the fact that I was on the m aste r branch of libserialport.

When I used the latest libserialport-0.1.1 tag, it worked perfectly.

As well as for libiio with the tag v0.24 and libad9361-iio with the tag v0.3

So I rebuilt liibio and iio-oscilloscope.

However, I get exactly the same errors.

Do you have any other options for solving this problem? Thank you for the time you took to solve my problem.

Rémi

Hi, Rémi.

When you say you get the exact same error, do you mean "the inappropriate ioctl for the device" or the ""Could not get iio context: Unknown error"?

Hi csuteu ,

On WSL, i get the error "the inappropriate ioctl for the device".

Regards,

Rémi

This is because the fix that resolved this issue is not included in version 0.1.1 of libserialport.

Could you try to build this specific commit instead of building the ma ster branch ?

git clone https://github.com/sigrokproject/libserialport.git

cd libserialport

git checkout 6f9b03e

./autogen.sh

./configure --prefix=/usr

make

sudo make install

Then you will have to rebuild libiio, and osc once again.

Let me know if this works for you.

Thanks.

-Cristina

Thank you for your reply.

I put myself on the 6f9b03e branch for libserialport as advised.

I rebuilt libiio and iio oscilloscope with the branches v0.24 and orign/ma ster.

But I still get the same error: inappropriate ioctl for the device

Could the error come from USRP E312? 

Could this thread help?  RE: serial connection with iio oscilloscope 

In particular, this post:

When I run ldd $(which iio_info), i get:  libserialport.so.0 => /lib/x86_64-linux-gnu/libserialport.so.0 (0x00007f8e51140000)

Should /usr be replaced by /lib/x86_64-linux-gnu/?

Thank you very much for all these answers.

Regards,

Rémi

The first thing that you want to do, is get a clean envinroment. It is possible that even though you have installed the correct version of libserialport at /usr/ location (the one that you compiled from the specific commit), the package that you installed via apt-get is still in the /lib/x86_64-linux-gnu , thus causing libiio to link to it and your subsequent error.

My recommendation is this : delete every instance of libserialport that is on your machine (in /usr/ ; in /lib/x86_64-linux-gnu ; etc). After this, rebuild the specific commit of libserialport as indicated. Install the rest of libiio's dependencies but make sure that you SKIP installing libserialport via apt-get.

Then you can proceed to build libiio and IIO-Oscilloscope. If you're still using Ubuntu 20, then please pay attention to not install libgtkdatabox via apt-get.

Instead you will have to do the following:

wget https://downloads.sourceforge.net/project/gtkdatabox/gtkdatabox-1/gtkdatabox-1.0.0.tar.gz

tar xvf gtkdatabox-1.0.0.tar.gz

cd gtkdatabox-1.0.0

./configure

(sudo) make install

If you have managed to build the app, please mark one of the replies as an answer to this thread. Alternatively, if you figured out another solution on your own, please reply with it and mark that as an answer.

Thank you.

Hi csuteu ,

Thank you very much for your help. Now IIO Oscilloscope works well like on my Windows computer.
