AM335x Starter kit: rowboat android using libGLESv1_CM_POWERVR_SGX530_125.so or libGLESv2_POWERVR_SGX530_125.so???I

Suchit Bhatt

Hi All,

I have a doubt for AM335x stater kit using OpenGL ES 2.0 or opengl ES 1.0 ..(we have android 4.1.2).In logcat we found

D/libEGL ( 215): loaded /system/lib/egl/libGLESv2_POWERVR_SGX530_125.so

Meaning of I/SurfaceFlinger( 80): version : OpenGL ES-CM 1.1 ? libGLESv2_POWERVR_SGX530_125.so not used.

My question is powersgx using ibGLESv2_POWERVR_SGX530_125.so this library?? Because some android application not running on starter kit with error supported only OpenGLESv2 or more...

Hi Suchit,
Only the latest JB 4.2.2 release is supported on AM335x platforms. Could you please reproduce the issue with JB 4.2.2? Otherwise, it would be challenging for us to support you effectively.

We are using Android Jelly bean 4.1.2 (TI AM335x) which is official provided by TI. Downloaded for here (software-dl.ti.com/.../index_FDS.html) .
My question is android using which OpenGl ES vserion ? Because in my logcat displayed version : OpenGL ES-CM 1.1.

Hi Suchit,

the latest release from TI is Jelly Bean 4.2.2, and we used this version in the following explanations, but this should also apply to your version.

We checked for a similar behavior in logcat and we can confirm that the surfaceflinger is using openGL ES CM 1.1and not open GL ES 2.0.
Checking Android.mk, we can see that binaries are linked manually against libGLESv1_CM.so. This is an android JB specific behavior, and was changed in KK.
example: libsurfaceflinger: frameworks/native/services/surfaceflinger/Android.mk

TI BSP relies on surfaceflinger for compositing surfaces, and therefore, has only openGL ES CM 1.1 capabilities.
In order to use openGL ES 2, you would need a hardwarecomposer, which is not provided within this BSP.

Some components might still be using openGLES2 in JB (libhwui for instance, used in 2d rendering path), but the final composition will rely on openGL ES CM 1.1
