I'm having issues getting GLES2.0 samples to run on the Neo as demonstrated here: http://www.udoo.org/udoobuntu-2-for-udoo-neo-we-got-it/ I first downloaded (fsl-gpu-sdk-2.2.tgz) from http://www.freescale.com/products/a...-m4-cores:i.MX6SX?fpsp=1&tab=Design_Tools_Tab I ran the binary installer and followed the steps in 'Doc/Setup_guide_ubuntu14.04.txt' sudo apt-get install build-essential libxrandr-dev sudo apt-get install libgles2-mesa-dev sudo apt-get install libopenvg1-mesa-dev sudo apt-get install libdevil-dev source prepare.sh FSL_GRAPHICS_SDK=/home/udooer/Downloads/fsl-gpu-sdk-2.2 build.sh finishes without problems. Then, executing > DemoApps/GLES2/S01_SimpleTriangle/S01_SimpleTriangle (board connected to 1080p HDMI display) Output: WARNING: Window Size/Position values not set, setting them to Full Resolution of Primary CRT ERROR: demo setup failed with: eglCreateContext(m_hDisplay, m_hConfig, EGL_NO_CONTEXT, contextAttribList) failed with error code 12293 at source/FslDemoHostEGL/EGLDemoHost.cpp(578) EGL error code 12293 is 0x3005 and corresponds to EGL_BAD_CONFIG. The i.MX6 Graphics SDK (gpu_sdk_v1.00.tar.gz) has similar samples which are done in c instead of c++. I then edited Makefile.x11 so that the code compiled: change TARGET_PATH_LIB to /usr/lib/arm-linux-gnueabihf/vivante change TAGET_PATH_INCLUDE to /usr/include/arm-linux-gnueabihf change -mfloat-abi=softfp to hard running 01_SimpleTriangle in the v1.00 SDK fails in an assert with an identical error. I have tried changing some of the attrib list in the c implementation, but keep getting the same error. Also, chromium is not using WebGL, I have attached the text output of chome://gpu.

Thanks, Angus
We are providing those sample applications already built in a deb package. Just type sudo apt-get install imx-gpu-viv-9t6-test You will find the samples inside /opt/.
Nevermind, looks like having libgles2-mesa-dev installed causes the es20 examples to break. I made a fresh image, ran apt-get update, upgrade, only installed package you suggested and everything works fine. Any idea why this is the case? Also still having the EGL_BAD_CONFIG assert fail in the examples. I'll be able to test more after exams.
