Linux/TMDXIDK5728: Linux SDK - Example Applications

Alec Phillips

Part Number: TMDXIDK5728

Tool/software: Linux

I am attempting to run the pre-built example applications from inside the Linux-RT filesystem. All of the example files are ELF 32-bit LSB executables, which cannot be run on a 64-bit Linux OS. What am I missing here?

I am using Linux RT v5.02. Ubuntu v16.04 LTS.

My course of action is as follows ->

open terminal in <ti-sdk>/example-applications/matrix-gui-browser-2.0/
execute file by entering "./matrix_browser"
"Cannot execute binary file: Exec format error"
enter command "file matrix_browser"
file type is ELF 32-bit LSB Executable, ARM, EABIS version 1.

Thank you,

Alec

Hello Alec,

You need to run these examples on your target board, not on your host machine. These examples are arm executable, not x86. Please, visit this page for more details.

Also, please close your previous this thread by clicking on "This resolved my issue" button. And do not forget to close this one too.

Note: If you insist to run this example on your host machine. Please, use these commands instead.

cd <Processor SDK>/
make matrix-gui-browser_clean
cd example-applications/matrix-gui-browser-2.0/
export QT_SELECT=qt5
sudo apt-get install qtwebengine5-dev
qmake
make -j 8
./matrix_browser http://www.ti.com/ --windowed

Best regards,
Kemal

Hi Kemal,
Thanks for clarifying this for me.

I will close my previous thread when I am finished with the inquiry. For now, I am not done with it so I am not marking anything resolved.

I will attempt to follow the steps you provided.

If I wanted to update a different application for my host machine, is there a place I can find these instructions?

Thanks again for your response,
Alec

Hi Kemal,

The instructions didn't work as expected:

Could not locate the qtwebengine5-dev package. Please advise.

Thank you,

Alec

Yes, the instructions are here. Please, also go through these materials in this and this post too.

Run this command first.

sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade && sudo apt-get autoremove && sudo apt-get autoclean &&sudo apt-get clean && sync

As instructed, I performed the command:

Kemal R. Shakir said:
sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade && sudo apt-get autoremove && sudo apt-get autoclean &&sudo apt-get clean && sync

It seemed to complete successfully.

But the qtwebengine5-dev is still unable to be located:

Please advise.

Thank you,

Alec

Manually download the packages and its dependencies from here and install them by using dpkg.

sudo dpkg -i [package_name_amd64].deb

Searching the xenial release (16.04 LTS), there is no listing for qtwebengine at all. The only package with the -dev on it was "libqtwebkit-dev". Please advise which is the correct package for installation.

I installed the "libqtwebdev-kit" successfully, but "qmake" is a qt5 command and was not recognized.

This example cannot run on Ubuntu 16.04, you need Ubuntu 18.04.

Kemal,

Which, if any, of the prebuilt examples can be run on Ubuntu 16.04? I want to test basic functionality in Linux. I do not have a touchscreen or camera with my IDK.

Thank you,
Alec

You can join your IDK and Ubuntu 16.04 to the same network and display the Matrix GUI by entering the IDK's IP to the Ubuntu 16.04's WEB browser. Please, read the "Remote Matrix" section in this page for more details.

The instructions provided on your linked page are very unclear to me as a new user. Can you please help me to understand how to accomplish this?

I have my IDK attached to our local area network with an IP address of 10.xx.xxx.xxx. (found using ifconfig)
My Linux laptop is connected via Wifi (does this matter?).
I've found my way to /usr/share/matrix-gui-2.0
Tried to execute the command "matrix_browser -qws http://my.idk.ip.address:80"
The error I get is "Running on a compositor with no screens is not supported".
The application is thinking I'm trying to send it to the touchscreen, even though to me, I'm telling it to go to the ip address as indicated.

Please help me figure this out. Thank you in advance.

This matters. You need to connect the IDK to the same Wifi router where the Laptop is already connected. They must be in the same network, with the same subnet mask and similar IP addresses, like 192.189.1.x.

You need to enter the IDK's IP address to the WEB browser's URL address bar in the Laptop, once you connected them both to the same network.

Kemal,
Thank you very much for your assistance. Now that my IDK and laptops are on the same networked switch, I can access the remote matrix.
