SK-AM62: get access to display application on am62

Hi James,

My recommendation would be to use Wayland if possible because we do not support X11.

Hi Krunal,

How to get access to visit the wayland in docker?

On PC, we can visit x11 through xhost to control the authority.

Is there any tool to control and visit the wayland?

Hi James,

When launching docker, you would need something like the following:

docker run -it --privileged \
-e XDG_RUNTIME_DIR=/tmp \
-e WAYLAND_DISPLAY=$WAYLAND_DISPLAY \
-v $XDG_RUNTIME_DIR/$WAYLAND_DISPLAY:/tmp/$WAYLAND_DISPLAY \
-v /dev/dri:/dev/dri -v /dev/pvr_sync:/dev/pvr_sync \
--device-cgroup-rule='c 199:* rmw' --device-cgroup-rule='c 226:* rmw' \
--user=$(id -u):$(id -g) -e QT_QPA_PLATFORM=wayland -e LD_LIBRARY_PATH=/usr/lib \

Hi Krunal,

I have tried the command above but it still have the following error message after I execute the python application

Does the application need other setting?

Hello James,

We have tested pyqt5 and pyqt5 w/ Docker. If you are running into touch issues, have you checked with the Qt community for guidance?

Hi Krunal,

I have checked the same issue on the Qt community but it cannot work.

The building environment I use is ubuntu 20.04 in Dockerfile.

Can you provide the Dockerfile or the environment you use?

Hi James,

I haven't tested this in Docker environment and I just shared with basic examples of what I found on Google.

Hi Krunal,

I see. There is an important thing that if the application need to display openGL but the terminal shows it cannot open tidss.

How to solve it?

Hi Krunal,

Yes. The error appears in the docker environment and following is the error message:

Using Wayland-EGL

libeGL warning: MESA-LOADER: failed to open tidss: /us/lib/dri/tidss_dri.so: ca not open shared object file: No such file or directory (search paths /us/lib/a arch64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri, suffix dri)

Hi James,

Based on the above error, it seems like your docker environment does not have the necessary GPU libraries. The error makes sense because your are running Ubunut Docker and our GPU libraries are not present as part of the default Ubuntu FS. One hack experiment would be to pass your libraries from host machine to your target docker machine or untar the following repo in your Docker FS.

Hi Krunal,

It means if I have the library package tidss_dri.so, the application can show the vision part.

In present, I just need to solve the building issue so that I can copy the library from the target to docker environment.
