eglMakeCurrent causes GL_INVALID_OPERATION

mastermind_ — Fri, 22 Aug 2014 13:36:10 GMT

Hi!

I have custom board with i.MX6S processor, version of SDK is 3.5.7-1.0.0 (from Buildroot).

The code eglMakeCurrent(egl_display, EGL_NO_SURFACE, EGL_NO_SURFACE, EGL_NO_CONTEXT) sets OpenGL error to GL_INVALID_OPERATION, while the eglMakeCurrent call returns EGL_TRUE. Is that bug in driver or what?

Code is well tested and runs on other platform (android) without any errors.

Thanks

Also I've reproduced it in sample 01_SimpleTriangle from SDK

Hello Denis,

Make sure that you have include GPU support on your BSP envioment, Also, instead if 3.5.7 please take a look at the i.MX6 Graphics SDK that Includes sample, demo code, and documentation for working with the i.MX6X family graphics cores. Includes OpenVG, OpenGL ES, and GAL2D reference files..

Hope this helps

Hello, I'm using the buildroot environment, which has 3.5.7 version and I'm not going to change it. It works great, just sets OpenGL error.
