Crash in gcoHAL_QueryChipCount when initializing OpenGLES on i.MX6D

On a MarSBoard with i.MX6 dual ( http://www.embest-tech.com/shop/star/marsboard.html ) I installed a yocto image build using recipes from silmerusse/meta-robomind

After installing I copiedIndex of /buildsources/g/gpu-viv-bin-mx6q/gpu-viv-bin-mx6q-1.1.0 over /usr.

A simple OpenGLES 2.0 app built with -DEGL_API_FB=1 crashes in gcoHAL_QueryChipCount.

A stacktrace:

#0 0x2ab19984 in gcoHAL_QueryChipCount () from /usr/lib/libGAL.so

#1 0x2aaf8ad0 in veglGetThreadData () from /usr/lib/libEGL.so

#2 0x2aaf1f30 in eglGetDisplay () from /usr/lib/libEGL.so

#4 0x00017d70 in main (argc=1, argv=0x7efffd04) at consoleapp.cpp:368

Site of crash:

bhi 0x2ab199ac <gcoHAL_QueryChipCount+84>

I tried to use gpu-viv-bin-mx6q-3.0.35-4.0.0 (using the softfp files) instead of gpu-viv-bin-mx6q-1.1.0 with similar results.

My questions are:

How does one determine the gpu-viv-bin-mx6q version to use?

How do I fix this crash?

The crash was caused by using the wrong version of libEGL/GAL. The version I needed was gpu-viv-bin-mx6q-3.0.35-4.1.0.

I just wanted to let you know that I was facing similar problems but with the hard-float binaries so I got the gpu-viv-bin-mx6q-3.0.35-4.0.0 and then it stopped crashing.
