Hi Li.
The NXP BSP for i.MX6 already includes OpenGL support. For additional details, please refer to Table 8 “Supported features” of the “i.MX Linux Release Notes” document (attached), and also, take a look to the second attached document (i.MX 6 EGL & OGL Extension Support).
Hope this will be useful for you.
Best regards!
/Carlos
