We are trying to use both background framebuffer (/dev/fb0) and overlay framebuffer (/dev/fb1) and enable global alpha blending. We need to use openGL in both applications but fbGetDisplayByIndex(1) fails. I am yet to dive deeper to understand the error code better. Is there any limitation in using OpenGL with Vivante graphics driver with /dev/fb1 overlay buffer? in i.MX6 Linux platforms?
Has anyone got it working with i.MX6?
