Graphic Accelerator with OpenGL ES on DM3730

Other Parts Discussed in Thread: DM3730, OMAP3530

I am trying to run the Qt OpenGL ES example hellogl_es2.

I invoke the command and get the following error:

# ./hellogl_es2 -qws -display powervr
powervr: driver not found
Aborted

Now I noticed that I have an error on startup, that is most likely related but I am not sure how to fix it or what causes it:

pvrsrvkm: Unknown parameter '/lib/modules/2.6.32/kernel/drivers/char/pvrsrvkm.ko'
insmod: error inserting '/lib/modules/2.6.32/kernel/drivers/gpu/pvr/pvrsrvkm.ko': -1 Unknown symbol i
n module

The standalone OpenGL examples like OGLES2Coverflow etc. work fine.

Thanks in advance

    Always baseline your system using below:

    - For the hellogl_es2, there are a number of factors that can cause it, take a look at -

    You can use the TI ezSDK as reference to make this work: Refer below link.

    Thank you very much for your response. This gives me some ideas.

    The EZDSK seems to only support the platforms TI DM816x and DM814x. Can I still use it even though I have DM3730?

    I went through the points of the checklist "qt_powervr_dbg.txt" linked from
     http://processors.wiki.ti.com/index.php/SGXDbg#Integration_of_Qt_framework_with_SGX_PowerVR_drivers_do_not_work
    and noticed, that I do not have the library file libpvrQWSWSEGL.so but only:
         # ls /usr/lib/qtopia/plugins/gfxdrivers
         libqgfxpvregl.so       libqgfxtransformed.so  libqgfxvnc.so
    Does this mean, that something with my installation went wrong?

    Here is my gfx_check.sh output, just for completeness. Is there maybe already something fundamentally wrong here?

    Yes - ensure you are configuring, building Qt with support for opengl es2 (take the ezsdk makefiles as reference).

    I was hoping to be able to run Qt with OpenGL es2 support, by installing prebuild Qt packages from the Angstrom Linux repository. They seem to support OpenGL ES2 also. Is this not recommended?

    It might support it, you can use the beagleboard.org forums for support on Angstrom. In any case, issues pointed out earlier need to be fixed.
