imx6 opengl (es) reference code

imx6q

linux 3.14.28

Have you provided sample code about IMX6 OpenGL (ES) based on bare framebuffer? I need the code based on /dev/fb0 or /dev/fb1, no window backend(X11 and so on).

Hi Gary,

Samples codes can be found in the GPU SDK package: https://www.nxp.com/webapp/Download?colCode=IMX6_GPU_SDK&location=null&Parent_nodeId=133763715453569... 

Also please check the OpenGL tutorial:

Hi Bio,

Could you provide the related GLES EGL.. libs and gcc toolchain?

Using the imx6 L3.14.28 yocto lib(fb backend) to build, the app throw an error when run.

Hi Bio,

Using the sdk you mentioned, I find some function missing:

../common/src/fsl_egl.o: In function `fsl_getNativeDisplay':
fsl_egl.c:(.text+0x18): undefined reference to `fbGetDisplayByIndex'
../common/src/fsl_egl.o: In function `fsl_createwindow':
fsl_egl.c:(.text+0x100): undefined reference to `fbCreateWindow'
collect2: error: ld returned 1 exit status

Do I need some extra lib?

I've found the correct libEGL.so. Thanks.

Hello. I have same problem, trying build OpenGL-fbdev application and have undefined reference to `fbGetDisplayByIndex' and undefined reference to `fbCreateWindow' errors.

It looks like libEGL.so have no fbGetDisplayByIndex and fbCreateWindow functions.

Where did you get correct libEGL.so ?
