How to draw two different 2D graphics using OpenGL ES on TI8168

Hi all:

    We use TI8168 platform, SDK is ezsdk_dm816x-evm_5_04_00_11_setuplinux。

    Now,we must use OpenGL ES to draw two different 2D graphics.I have build Graphics SDK.But I found I can only open fb0 using egl function.

    How can I draw two different 2D graphics using OpenGL ES?

    Thanks!
