Linux/BEAGLEBK: Arago with Qt5 and OpenGL questions

Daniel Gorsulowski
Prodigy 250 points

Part Number: BEAGLEBK

Tool/software: Linux

Hello,

I'm trying to build an image for BeagleBone Black with Qt5 and opengl using arago.

Q1: Which is the prefered way doing this?

I'm following Setting Up Build Environment

Q2: The link to gcc-linaro-5.3-2016.02-x86_64_arm-linux-gnueabihf is deprecated. Should I use exactly this toolchain (already found it elsewhere), or should I use the latest gcc-linaro-5.4.1-2017.01-x86_64_arm-linux-gnueabihf toolchain?

Q3: Which is the preferred layersetup? configs/amsdk/amsdk-08.00.00.00-config.txt or configs/arago-krogoth-config.txt?

Q4: Which is an appropriate (minimalistic) bitbake target to build an image with a QT5 opengl example, i.e. cinematicexperience?

Q5: How do I start this example? Is "Qt5_CinematicExperience -platform eglfs" correct?

Q6: Currently I'm working with the following setup: configs/arago-krogoth-config.txt and arago-base-tisdk-image bitbake target. Additionally I added packagegroup-arago-tisdk-qte and cinematicexperience to IMAGE_INSTALL_append in beaglebone.conf file and called it beagleboneng.txt.

This Image boots, but something is missing:

Is the SGX package available for this kernel? As I remember, the latest supported kernel is 3.14, or am I wrong?

    Rebuilding the images is okay, the prebuild images from the Processor SDK would work too.

    You should use the exact toolchain version that the SDK has built and released, the usage of other older or newer toolchain is not recommended.

    The latest preferred layersetups are configs/processor-sdk/processor-sdk-<version>-config.txt. This forum supports only these configs.

    MACHINE=am335x-evm bitbake tisdk-rootfs-image

    Yes, it is correct.

    This Image boots, but something is missing:

    You are missing the ti-sgx-ddk-km and ti-sgx-ddk-um recipes. Please, build and install them too.

    Best regards,

    Hi,

    is the create-sdcard.sh mentioned here available via git repository or direct download, or do I have to download and install the whole Processor SDK to obtain this script?

    If you desire you can also clone it.
    git clone git://arago-project.org/git/projects/tisdk-setup-scripts.git

    Finally, build is done and somehow I got the image to sd-card - the target boots.

    I guess, I have to stop weston:

    eglinfo shows:

    Can you attach the gfx_check.log gathered with the gfx_check.sh script?

    Sure, here you are (this will expire after 90 days):

    https://paste.debian.net/plain/924877

    Btw. why do I get this if I try to reply to your question with the attached log?

    You have posted to a forum that requires a moderator to approve posts before they are publicly available.

    Ok, forget the last question. Obviously the post was to long and had to be validated to prevent abuse.

    Some further tests on my own:

    I tried to switch to switch the WindowSystem to libpvrQWSWSEGL.so via /etc/powervr.ini. But this lib is not available

    root@am335x-evm:~# find /usr/lib -name libpvr*.so
/usr/lib/libpvrGBMWSEGL.so
/usr/lib/libpvr2d.so
/usr/lib/libpvr_wlegl.so
/usr/lib/libpvrDRMWSEGL.so
/usr/lib/libpvrws_WAYLAND.so

    How do I get this lib into my rootfs?

    Another Test:

    I switched to WindowSystem=libpvrGBMWSEGL.so via /etc/powervr.ini

    If I run

    root@am335x-evm:~# /usr/share/qt5/examples/opengl/hellogl2/hellogl2 -platform eglfs
failed to load module: /usr/lib/gbm/gbm_dri.so: cannot open shared object file: No such file or directory
failed to load module: /usr/lib/gbm/gbm_gallium_drm.so: cannot open shared object file: No such file or directory
loaded module : gbm_pvr.so
found valid GBM backend : gbm_pvr.so
Could not set DRM CRTC mode! (Invalid argument)
procPageFlipReq(): failed to add crtc atomically (Invalid argument)

    Nothing happens on screen (DVI) and hellogl2 burns nearly 100% CPU.

    Do I have to switch somehow from LCD to DVI? (there is no LCD cape attached)

    Hello Daniel,

    Sorry for my late reply. I think you met the same issue as in this thread. Can you check?

    Best regards,

    I replaced the lib as you suggested in this thread. But its binary compatible.

    root@am335x-evm:~# cd /usr/lib
root@am335x-evm:~# mv libpvrDRMWSEGL.so.1.14.3699939 libpvrDRMWSEGL.so.1.14.3699939_ori
root@am335x-evm:~# wget e2e.ti.com/.../libpvrDRMWSEGL.so.1.14.3699939
root@am335x-evm:/usr/lib# cmp libpvrDRMWSEGL.so.1.14.3699939 libpvrDRMWSEGL.so.1.14.3699939_ori
root@am335x-evm:/usr/lib#

    I switched to this lib via /etc/powervr.ini. Now eglinfo shows:

    libpvrQWSWSEGL.so is a part of libpvrqwswsegl1 which gets created while building qt4-embedded-gles

    Hi!

    Does that mean, I don't need this lib if I have QT5 apps only?

    And what about the error messages above?

    Further questions:

    How do I get /opt/gfxsdkdemos to my rootfs? (which bitbake target is needed)

    Many pages point out that an omaplfb.ko is needed. But there is no omaplfb.ko in my rootfs. How about that?

    Can you type this command root@am335x-evm:~# echo DefaultPixelFormat=RGB565 >> /etc/powervr.ini then retry?

    How do I get /opt/gfxsdkdemos to my rootfs? (which bitbake target is needed)

    I answer myself: I added "img-pvr-sdk" to IMAGE_INSTALL_append in am335x-evm.conf to get these demos/examples.

    And one success report: These OGLES2 examples run smoothly!

    You should be able even run the Qt5_CinematicExperience example, if you export QT_QPA_EGLFS_INTEGRATION=none
