Hi  
  
In Galaxy S, it was not able to get status because application crashed when glCheckFramebufferStatus was called.  
Output by “adb shell cat /proc/pvr/version” is as follows.  
  
&nbsp; Version 1.6.16.3947 (release) smdkc110\_android  
&nbsp; System Version String: SGX540 S5PC110  
  
  
This problem occurred in the source code such as the following.  
  
&nbsp; // create renderbuffer  
&nbsp; GLuint renderbuffer;  
&nbsp; glGenRenderbuffers( 1, &renderbuffer );  
&nbsp; glBindRenderbuffer( GL\_RENDERBUFFER, renderbuffer );  
&nbsp; glRenderbufferStorage( GL\_RENDERBUFFER, GL\_DEPTH\_COMPONENT16, 1, 1 );  
&nbsp; glBindRenderbuffer( GL\_RENDERBUFFER, 0 );  
  
&nbsp; // create framebuffer  
&nbsp; GLuint framebuffer;  
&nbsp; glGenFramebuffers( 1, &framebuffer );  
&nbsp; glBindFramebuffer( GL\_FRAMEBUFFER, framebuffer );  
&nbsp; glFramebufferRenderbuffer( GL\_FRAMEBUFFER, GL\_DEPTH\_ATTACHMENT, GL\_RENDERBUFFER, renderbuffer );  
&nbsp; glBindFramebuffer( GL\_FRAMEBUFFER, 0 );  
  
&nbsp; // check framebuffer status  
&nbsp; glBindFramebuffer( GL\_FRAMEBUFFER, framebuffer );  
&nbsp; if ( glGetError() != GL\_NO\_ERROR ) {  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; LOGE( “GL error” );  
&nbsp; }  
&nbsp; LOGD( “Start glCheckFramebufferStatus()” );  
&nbsp; if ( glCheckFramebufferStatus( GL\_FRAMEBUFFER ) != GL\_FRAMEBUFFER\_COMPLETE ) {  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; LOGE( “framebuffer is incomplete!” );  
&nbsp; }  
&nbsp; LOGD( “End glCheckFramebufferStatus()” );  
&nbsp; glBindFramebuffer( GL\_FRAMEBUFFER, 0 );  
  
  
The following log is output in glCheckFramebufferStatus call in the source code above, then the application was terminated abnormally.

Hi,  
  
Have you been able to resolve your problem yet?  
  
The crash is likely due to a driver bug. Unfortunately, I'm not sure if that device will get another official driver update.  
  
I've noticed that there seem to be some errors in your framebuffer setup. For example:  

1. You should only unbind the renderbuffer and framebuffer&nbsp; at the end of the frame buffer's setup, as they must be bound during the setup
2. You are creating a depth buffer that is 1x1. Is this correct? For a non-antialiased FBO, the resolutions of any colour, depth and stencil attachments should match

Thanks,

Joe
