Hellogl_es2 example: could not initialize EGL display

Nina Weber
Intellectual 445 points

Hello,

I have the AM335x EVM and currently installed Qt4. I did the Hands on with Qt Lab 1 und Lab 2 and everything works well. I skipped 3 and 4 as I won't be working with the Qt Designer, but another example I created including buttons and signals and everything runs well also.

Now I wanted to do Lab 5 and I find all the files, I changed the powervr.ini like instructed in step 7, but when I issue the command from step 8

" ./hellogl_es2 -qws -display powervr"


it says

"Could not initialize EGL display - are the drivers loaded?

Segmentation fault"

Can anybody please help me?

I really want to do some applications using openGL, and if this example application doesn't even work, my own applications most probably won't work, I guess?

Tell me if you need additional informations, as I am new to Qt and haven't used the AM335x for long I don't know, what you might need.

Thanks in advance!

    Hi,

    Please post which EVM board and Linux version you are using.

    I'm using ubuntu 14.04 on a virtual machine and the 06.00.00.00 SDK and the AM335x EVM with ARMv7 Processor

    Do you have the Graphics SDK installed?

    Intellectual 445 points

    That could be something. I haven't installed it knowingly, so probably not. How do I install that? Is this the tutorial:

    http://processors.wiki.ti.com/index.php/Graphics_SDK_Quick_installation_and_user_guide

    But I am a bit confused, since in the prerequisites for the hands on tutorial it says nothing about installing this SDK...

    Ok great, thanks. I am gonna try that. Do I only need to do the install steps or something else too?

    Just follow the wiki instructions.

    Ok, I covered the install steps, that seemed to have worked. I installed the Graphics_SDK_setuplinux_4_10_00_01.bin to /home/sitara. But now it says "

    1. Change the directory to ~/Graphics_SDK_#_##_##_##

    Can't do that since I don't find that folder. Is it supposed to be in /home/sitara? I only have folders labeled

    This is really embarassing...since I installed it to /home/sitara it didn't create the Folder Graphics-.... It just put all the stuff in the sitara folder directly...so the Rules.make is lying there...sometimes you can't see the wood for the trees....

    Ok, now I am a bit confused modifying the Rules.make file. I don't know to what I should set the CSTOOL_DIR field. Where can I find out what toolchain I am using? the suggested arm-2009q1 it won't find...

    When I did the tutorial hands on with qt I used the arm-linux-gnueabihf-gcc and arm-linux-gnueabihf-gdb files found in /home/sitara/ti-sdk-<machine>-<sdk version>/linux-devkit/sysroots/i686-arago-linux/usr/bin. Does that help maybe?

    For the KERNEL_INSTALL_DIR and the TARGETFS_INSTALL_DIR field I don't even know where to start looking for somehing.

    I only modified the bold text in the Rules.make file

    thanks a lot for your post, that helps!

    But I can't find anything, that resembles your gcc-linaro-arm-linux...path for the toolchain path. How did you find your path? Did you put it there manually or was it installed with your 06.00.00.00 SDK? The only thing I find that remotely reminds me of a toolchain folder is the one in the linux-devkit folder  /home/sitara/ti-sdk-<machine>-<sdk version>/linux-devkit/sysroots/i686-arago-linux/usr/bin.

    edit: and also I don't have  /home/sitara/filesystem/arago-base-tisdk-image-am335x-evm,
    I only have /home/sitara/filesystem/arago-base-tisdk-image-am335x-evm.ubi

    Hi Nina,

    O'K. Please download from http://software-dl.ti.com/sitara_linux/esd/AM335xSDK/latest/index_FDS.html the linaro toolchain and install it. For more clarity please see from Graphics_4.. directory README.txt file. They recommended:

    "Toolchain

     Arago Dynamic toolchain based on GCC 4.5.3 for all devices (supplied with AMSDK releases).
     Linaro 4.7.3 hardfp toolchain(arm-linux-gnueabihf-) was used for creating the hardfp package.
    What is supported  "

    Hi Ivan,

    I will download this one: software-dl.ti.com/sitara_linux/esd/AM335xSDK/latest/exports/am335x-evm-sdk-src-07.00.00.00.tar.gz and install it in the same directory where I got the 06.00.00.00 SDK? 

    I don't quite understand about toolchains and everything, but does it matter to have two?

    Hi Nina,

    For good instalation of Graphics_SDK_4.. you must have good instalation of SDK 6.0 and Linaro toolchain. You can reinstall SDK 6 on the clear place. In the /home/users/imatrakov/ti-sdk-am335x-evm-06.00.00.00/filesystem you manualy have to unzipped the arago-base-tisdk-image-am335x-evm.tar.gz file and don't forget changes in Rules.make
    If you want to use SDK 7 you have to know that you must install Graphica_SDK_5 and there only one toolchain is used - linaro 4.7.3

    I installed the SDK 6.0. previously and everything worked up until I wanted to use OpenGL.

    when I try to unzip the arago-...tar.gz file it unzips some folders, but exists with

    "tar: Exiting with failure status due to previous errors".

    Then I ran the make OMAPES=8.x all command and it took about 10 minutes installing stuff, but now it says:

    ******************************************************************************

    so I changed ARCH=arm in the Rules.make file

    when I run the make OMAPES=8.x all command now, it doesn't exit with Errors. Does that mean it worked?

    What do I have to do next? I don't understand the next part of the tutorial (http://processors.wiki.ti.com/index.php/Graphics_SDK_Quick_installation_and_user_guide)

    and what do you mean by

    "...
    copy OGLES2 demo dependant files.../home/users/imatrakov/Graphics_SDK_4_10_00_01/GFX_Linux_SDK/OGLES2/SDKPackage/Demos/DeferredShading/OGLES2/scene.pod
    copy OGLES2 demo dependant files.../home/users/imatrakov/Graphics_SDK_4_10_00_01/GFX_Linux_SDK/OGLES2/SDKPackage/Demos/ParticleSystem/OGLES2/sphere.pod
    copy OGLES2 demo dependant files.../home/users/imatrakov/Graphics_SDK_4_10_00_01/GFX_Linux_SDK/OGLES2/SDKPackage/Demos/PhantomMask/OGLES2/PhantomMask.pod"

    ?

    By the way, I still get the same error, when trying to run the hellogl example.

    Hi Nina,

    You have to use sudo if you don't unzipped the arago file systems. With the final lines  finish installation of Graphics_SDK_6. If you see them you installed well the Graphics_SDK.

    Hi,

    hope you had a nice weekend!

    so, I unzipped the arago filesystem again, using the sudo command, and then I did the "make OMAPES=8.x all" again. It took some time, but the last lines were

    "...

    copy OGLES2 demo dependant files.../home/sitara/Graphics_SDK_4_10_00_01/GFX_Linux_SDK/OGLES2/SDKPackage/Demos/Navigation3D/OGLES2/CM_US_IL_CHICAGO_013_016_L.DAE.pod
    copy OGLES2 demo dependant files.../home/sitara/Graphics_SDK_4_10_00_01/GFX_Linux_SDK/OGLES2/SDKPackage/Demos/DeferredShading/OGLES2/pointlight.pod
    copy OGLES2 demo dependant files.../home/sitara/Graphics_SDK_4_10_00_01/GFX_Linux_SDK/OGLES2/SDKPackage/Demos/DeferredShading/OGLES2/scene.pod
    copy OGLES2 demo dependant files.../home/sitara/Graphics_SDK_4_10_00_01/GFX_Linux_SDK/OGLES2/SDKPackage/Demos/ParticleSystem/OGLES2/sphere.pod
    copy OGLES2 demo dependant files.../home/sitara/Graphics_SDK_4_10_00_01/GFX_Linux_SDK/OGLES2/SDKPackage/Demos/PhantomMask/OGLES2/PhantomMask.pod"

    so I assume it went all right?

    But I still can't run the hellogl_es2 example. It still says

    "Could not initialize EGL display - are the drivers loaded?

    Segmentation fault. "

    Did I still miss something while installing the Graphics SDK? Or is there some other issue to be solved for the example to run?

    How do I proceed in the tutorial? The next step would be

    For AM335x-

    setenv bootargs 'console=ttyO0,115200n8 root=/dev/nfs nfsroot=<nfshostipaddress>:<rootpath>,nolock 
    rw mem=256M ip=dhcp earlyprintk=serial vram=50M' 

    But I don't know what to put in the <nfshostipadress>:<rootpath> field. 
    Is this the ip adress of my AM335x EVM?
    I tried this:
    xferwebn@xferwebn-VirtualBox:/mnt/hgfs/vbox_shared$ tcsh
    xferwebn-VirtualBox:/mnt/hgfs/vbox_shared> setenv bootargs 'console=ttyO0,115200n8 root=/dev/nfs 
    nfsroot=192.186.0.1:/home/root/,nolock rw mem=256M ip=dhcp earlyprintk=serial vram=50M'


    but it doesn't give any feedback. Now I looked for the 335x-demo, but I only found it in the folder targetfs in the
    ti-sdk folder. 
    Running it with ./ only results in this error:
