AM3358: matrix_browser not working properly

Mohamed Fayed
Prodigy 50 points
Part Number: AM3358


Hi TI Team,

I am trying to build an image that has the minimum requirement for web-browser for a kiosk application.

SOC:  beaglebone black with external HDMI (no special HW).

SDK: Processor SDK Linux for AM335X  Ver. 07_03_00_005

I followed the instruction found  in here:  https://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Overview_Building_the_SDK.html

to build the yocto build for the SDK.

I managed to build it successfully. 

When I try to start the matrix_browser I always get white screen with the mouse pointer visible, with some complains as follows:

root@am335x-evm:~# /usr/bin/matrix_browser www.google.com
qt.qpa.input: xkbcommon not available, not performing key mapping
Attribute Qt::AA_ShareOpenGLContexts must be set before QCoreApplication is created.

I tried some other examples some of them work without any problem and some of them did not work.

Here is some examples of the examples I tried and the results.

A- Working Examples:

    Hello Mohamed,

    Do you have weston enabled and if yes, do you see the weston screen?

    Regards,

    Thank you Krunal for your reply.

    After booting my HDMI screen is black and I know there is an issue that the matrix gui is not starting up automatically.

    On HDMI screen I can see the matrix_gui after executing the following commands

    root@am335x-evm:~# export QT_QPA_PLATFORM=eglfs

    root@am335x-evm:~# /etc/init.d/matrix-gui-2.0 start

    Acording to this page:

    https://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Foundational_Components/Graphics/Graphics_and_Display.html

    After I exit weston using  Ctrl-Alt-Backspace  then  Ctrl-Alt-F1. 

    none of the demo apps is working, here is the output:

    root@am335x-evm:~# /usr/bin/SGX/demos/DRM/OGLES2Coverflow

    Hi,

    Did you follow the instructions mentioned in the following page: https://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Foundational_Components/Graphics/AM3_Beagle_Bone_Black_Configuration.html?highlight=beagle . After adding the changes, try the command "/etc/init.d/weston restart"

    Also, before running any GPU application, try running kmstest to ensure display is functional. 

    Regards,

    Krunal

    Hi Mohamed,

    I am confused with your setup because in the post you mentioned about using 07_03_00_005. However, in the following message "Failed to load /lib/modules/5.4.20/extrapvrsrvkm.ko: No such file or directory", it says Kernel 5.4.20 but that's not the version our SDK supports. 

    Also, you mentioned "After restarting weston: The screen has white screen with mouse pointer and a title bare that has the current date and time" and that tells me Weston loaded and GPU is working. If GPU was not functional, the Weston screen will never come up. As an experiment, try running glmark-drm-wayland in that white screen.

    Regards,
    Krunal

    First I hit the resolve button by mistake. 

    I am using SDK 07_03_00_005 Here is the output of uname -a

    root@am335x-evm:~# root@am335x-evm:~# uname -a

    Linux am335x-evm 5.4.106-g023faefa70 #1 PREEMPT Fri Mar 11 23:21:14 UTC 2022 armv7l armv7l armv7l GNU/Linux

    I downloaded the SDK and built it without editing any file just to try it. So if the SDK does not support Kernel 5.4.20, Which version should I use.

    I used: MACHINE=am335x-evm bitbake  tisdk-default-image

    Also I tried to run  glmark-drm-wayland but it did not work

    I tried this: 

    root@am335x-evm:~# root@am335x-evm:~# glmark2-es2-wayland

    I can see 3d figure animation on  the screen started with a horse.

     

    No if I try to run the browser here is what I am getting a slightly different message:

    root@am335x-evm:~# /usr/bin/matrix_browser http://www.google.com
    qt.qpa.input: xkbcommon not available, not performing key mapping
    EGL Error : Could not create the egl surface: error = 0x300b

    Aborted (core dumped)
    root@am335x-evm:~#

    Appreciate taking the time to help,

    Hi Mohamed,

    Okay, let's take a step back and burn a SD card using the default images present in the SDK. Here are the instructions: https://software-dl.ti.com/processor-sdk-linux/esd/docs/07_03_00_005/linux/Overview/Processor_SDK_Linux_create_SD_card_script.html. 

    After, booting the board, make the changes mentioned in the following document: https://software-dl.ti.com/processor-sdk-linux/esd/docs/07_03_00_005/linux/Foundational_Components/Graphics/AM3_Beagle_Bone_Black_Configuration.html?highlight=beagle%20bone and reboot the board. At this point, you should see a white screen (Weston) with a cursor and you should be able to run glmark-es2-wayland.

    Hi Krunal,

    I  created an SD card from the TI-SD not from the yocto build.

    First, I got one complain about QT_WAYLAND_SHELL_INTEGRATION=wl-shell

    root@am335x-evm:~# matrix_browser www.google.com --windowed qt.qpa.wayland: "wl-shell" is a deprecated shell extension, prefer using "xdg-shell-v6" or "xdg-shell" if supported by the compositor by setting the environment variable QT_WAYLAND_SHELL_INTEGRATION

    So I switched to xdg-shell:  ~# export QT_WAYLAND_SHELL_INTEGRATION=xdg-shell     ==>> same result

    root@am335x-evm:~# echo $QT_WAYLAND_SHELL_INTEGRATION
    wl-shell

    root@am335x-evm:~# export QT_WAYLAND_SHELL_INTEGRATION=xdg-shell
    root@am335x-evm:~# echo $QT_WAYLAND_SHELL_INTEGRATION
    xdg-shell
    root@am335x-evm:~# matrix_browser www.google.com --windowed

     

    I tried also xdg-shell-v6: ~# export QT_WAYLAND_SHELL_INTEGRATION=xdg-shell-v6     ==>> same result

    root@am335x-evm:~# export QT_WAYLAND_SHELL_INTEGRATION=xdg-shell-v6
    root@am335x-evm:~# echo $QT_WAYLAND_SHELL_INTEGRATION
    xdg-shell-v6
    root@am335x-evm:~# matrix_browser www.google.com --windowed

    When I  click the right mouse button I got the box that says reload. Here is aa screen shot from the HDMI screen:

    glmark2-es2-wayland is working and I can see the 3d animations (It was also working with the SD card created from the yocto build).

    still getting the same error when I try glmark2-es2-drm

    Regards,

    HI Mohamed,

    Thank you for the confirmation! On my setup, I am able to run glmark2-es2-wayland but the drm test fails. I am not sure what your goals are but if you are just trying to run applications without weston you could try the following as an example: 

    1) root@am335x-evm:/usr/share/qt5/examples/opengl/hellogl2# ./hellogl2 --platform eglfs
    2) kmscube --format=RG16

    With regards to browser, the Yocto community removed all chromium based browsers because of Python2 dependency. I believe Python2 became EOL in 2020 and in Dunfell, any packages that depend on Python 2 were removed and not supported. The matrix browser is a non chromium based browser but I am not sure how much support is available from Qt community.  

    Regards,
    Krunal
