Hi,

We are trying to run OpenGL QT examples and GPU tests in unit_tests folder on i.MX6Q based custom board all following are the images rendered on screen.

QT OpenGL test output is shown below(Run examples/opengl/hellogl_es2/hellogl_es2)

 

 

 

and running gpu test(./unit_tests/gpu.sh) gives following output

 

 

Both these test run fine on SABRE AUTO board. The main change in custom board is DDR. Following are the DDR connection details

Total DDR Size : 1Giga Byte

No of chips :  4(256 MB each)

Following is DDR3 interfacing diagram,
