Hello,
Below are the steps needed to get hardware OpenGL ES
acceleration on BeagleBone Black running Debian. I wasn’t able to
find such instructions anywhere. Maybe someone could put this up
on the wiki?
I wanted to test 3D acceleration because I have been researching
the possibility to run Qt Quick 2 applications directly on the
BBB. First I tried running them under X in 24bpp (software
rendering) and it was impossibly slow. Then I tried running them
under X in 16bpp (software rendering) and they didn’t start
(please shout if you know the reason for this error and how to
fix it):
Cant find EGLConfig, returning null config
Unable to find an X11 visual which matches EGL config 0
Could not initialize OpenGL
Then I tried running them using the EGLFS platform and it worked,
but for this I had to install the drivers. Hence the instructions.

They are on the wiki..

3 steps to get hardware OpenGL ES acceleration on BeagleBone
Black running Debian (tested 2015-10 on wheezy, jessie and sid).
Note that after following the steps you will be able to run a
single fullscreen OpenGL ES application (e.g. Qt Quick 2 in EGLFS
mode) and nothing else, meaning:
* 3D acceleration in X server doesn't work on BBB and apparently
won't work anytime in the future
* Wayland can run with accelerating compositing (window drawing
handled by the GPU chip), but starting OpenGL applications
won't work. For this to work the graphics driver must have
built-in Wayland support, exposing the EGL_EXT_platform_wayland
EGL extension. Robert Nelson mentioned on IRC that TI is
working on this and progress can be followed here:
http://git.ti.com/gitweb/?p=graphics/omap5-sgx-ddk-um-linux.git;a=summary
1. First pick a kernel version from this list of kernel modules
for the GPU (the packages are from the
Index of /debian repo):
$ apt-cache search ti-sgx-es8-modules
Then install the kernel together with the modules. For
example, if you picked ti-sgx-es8-modules-3.14.54-ti-r77, run:
$ apt-get install -y
{ti-sgx-es8-modules,linux-image,linux-firmware-image}-3.14.54-ti-r77
2. On an x86 Linux computer run this (an x86 host is needed
because an x86 binary installer from TI will be unpacked):
$ git clone GitHub - RobertCNelson/ti-linux-kernel-dev: vendor bsp...
$ cd ti-linux-kernel-dev
$ ./sgx_create_package.sh
$ scp deploy/GFX_*_es8.x.tar.gz <address_to_your_bbb>:/tmp/
3. Now install the utilities on your BBB and reboot:
$ cd /
$ sudo tar zxf /tmp/GFX_*_es8.x.tar.gz
$ sudo /opt/gfxinstall/sgx-install.sh
Qt Quick 2 fullscreen programs can be launched from the terminal
or within Wayland by exporting these variables:
$ export QT_QPA_PLATFORM=eglfs
$ export QT_QPA_EVDEV_KEYBOARD_PARAMETERS="grab=1"
$ export QT_QPA_EVDEV_MOUSE_PARAMETERS="grab=1"
Wayland with accelerated compositing (but without the possibility
to launch windowed OpenGL programs) can be run like this:
$ weston-launch -- --backend=fbdev-backend.so --use-gl
